Question 1

Frame shipping costs depend on transport mode, chargeable weight, and Incoterms. Compare express, air, and sea options, and see how to get an accurate quote.

Accepted Answer

Frame order shipping costs depend on three things: the transport mode you pick, the chargeable weight of the shipment, and the Incoterm in your contract. Samples typically move by express courier, small bulk orders by air, and full collections by sea freight, which is usually the cheapest per unit for anything above a few cartons. There is no single fixed price, so the practical answer is knowing how each mode is billed and what to prepare for an accurate quote.Shipping Modes ComparedModeTypical transitBilling logicBest forExpress (DHL/FedEx/UPS)3-7 days door to doorPer kg with volumetric weight rulesSamples, urgent small lotsAir freight5-10 days airport to airportChargeable weight, plus local feesSmall bulk orders, launchesSea LCL20-35 daysPer cubic meterMedium orders sharing a containerSea FCL20-35 daysFixed per containerFull container programsWhat Drives the Final NumberChargeable weight: forwarders bill whichever is greater, actual weight or volumetric weight, so bulky light cartons cost more than their scale weight suggests.Incoterm: EXW leaves all freight on you, FOB puts sea legs on the buyer, and DDP delivers duty-paid at a higher invoice price; agree this in writing before booking.Packing: inner boxes, cases, and display units add volume; compact packing lowers sea freight noticeably on big orders.Destination fees: customs clearance, duties, and delivery from port vary by country and are quoted separately.Rates fluctuate with fuel, season, and lane demand. Treat any online estimate as a reference only, and confirm with a forwarder using real carton dimensions and weight before budgeting.READSUN ships worldwide from Ningbo and Shanghai ports and can quote freight alongside production.

Question 2

Importing optical frames from China runs eight steps: supplier check, audit, sampling, order, QC, freight, customs, and delivery. Here is the full process map.

Accepted Answer

Importing optical frames from China follows eight practical steps: shortlist a manufacturer, audit the factory, approve samples, place the order, run quality inspection, book freight, clear customs, and distribute. Most problems come from skipping one of these stages, so this guide walks through each step, the documents involved, and the mistakes that cost importers the most money.The 8-Step Import ProcessShortlist suppliers: compare manufacturers by material focus, certifications, and export experience rather than price alone.Audit the factory: verify it is a direct factory, review ISO and social compliance documents, or visit in person.Approve samples: confirm fit, finish, and packaging on countersamples, then freeze the spec sheet as the production standard.Place the order: sign a contract fixing prices, lead time, quality standards, and payment terms.Inspect quality: run in-line checks plus a pre-shipment inspection against the agreed standard before paying the balance.Book freight: choose express, air, or sea based on volume and urgency, and agree the Incoterm such as FOB or EXW.Clear customs: submit the commercial invoice, packing list, and the correct HS code classification for frames at destination.Distribute: receive into your warehouse or 3PL and check cartons against the packing list.Documents and Compliance ChecklistDocumentWhere it comes fromWhy it mattersCommercial invoice & packing listSupplierBasis for customs valuation and clearanceTest reports (CE, ANSI, FDA as applicable)Supplier or labProves product compliance at destinationBill of lading / airway billFreight forwarderTitle and transport documentImport declarationCustoms brokerLegal entry with correct HS code and dutyCommon Mistakes to AvoidThe costliest errors are choosing a trading company disguised as a factory, skipping the pre-shipment inspection, leaving compliance paperwork until after production, and shipping without written Incoterms.

Question 3

Electroplating bonds a thin metal layer onto frames for color, corrosion resistance, and skin safety. Learn the layer stack, thickness, and nickel-free options.

Accepted Answer

Electroplating in eyeglass frame manufacturing is the process of depositing a thin metal layer onto a frame by electric current, giving metal frames their color, corrosion resistance, and skin-safe surface. A typical plating stack runs copper, then nickel or a nickel-free barrier, then a precious or protective top coat such as gold, palladium, or gunmetal. The plating controls both how the frame looks on day one and how it wears after months of skin contact, so buyers should treat coating specs as seriously as the base metal.The Plating Stack, Layer by LayerLayerPurposeWhat buyers should checkCopper baseLevels the surface and improves adhesionEven base prevents peeling laterNickel or barrier layerCorrosion barrier between base and top coatNickel-free barrier for sensitive-skin marketsPalladium / gold / color topFinal color, luster, and tarnish resistanceCoating thickness in microns, agreed in writingProtective lacquer (optional)Extra scratch and sweat resistanceAsk whether it affects the finish toneWhy Coating Specs Matter for Your ProgramSkin safety: coating thickness and the barrier layer decide nickel release, which EU and US markets regulate; request EN 1811 test reports for metal parts.Durability: sweat, perfume, and salt air attack thin coatings, so higher-wear programs justify thicker precious-metal layers.Consistency: color must match across temples, rims, and hinges, which depends on bath control and jig discipline.Warranty link: peeling or flaking plating is a top return reason, so agree the coating standard and claim policy before mass production.READSUN plates metal frames in-house with controlled bath lines, including nickel-free routes for sensitive-skin collections. Review the equipment behind the plating shop on our manufacturing capabilities page, see plated styles in custom optical frames, and read about the team on about READSUN Optical or the READSUN Optical homepage.Plating thickness, color tone, and nickel-free requirements vary by market.

Question 4

Titanium frames are welded by laser or argon arc welding under shielding gas. See how the process works, why it demands skill, and what it means for price.

Accepted Answer

Titanium frames are welded with laser welding or argon arc (TIG) welding, and the choice depends on the joint design and order volume. Titanium reacts with oxygen at welding temperature, so the joint must be shielded by argon gas while the metal is fused. Done correctly, the weld is as strong as the base wire and nearly invisible after polishing; done poorly, it becomes brittle, discolored, and prone to cracking, which is why titanium frames cost more to make than nickel silver or monel ones.How the Welding Process WorksJoint preparation: the wire ends are cleaned and fitted so the gap is tight; contamination or gaps cause weak welds.Argon shielding: gas flows over the joint to block oxygen, because hot titanium absorbs nitrogen and oxygen and embrittles instantly.Fusing: a laser beam or TIG arc melts the wire ends together; laser welding offers pinpoint control for bridges and pad arms, while TIG suits thicker joints.Cooling and inspection: the joint cools under continued shielding, then welds are checked for porosity, cracks, and alignment.Finishing: the weld bead is ground and polished until the joint disappears into the frame line.Laser vs Argon Arc Welding at a GlanceAspectLaser WeldingArgon Arc (TIG) WeldingPrecisionVery high, ideal near rims and hingesModerate, larger heat zoneSpeedFast for small repeat jointsSlower, more operator skillHeat impactMinimal distortionMore discoloration to reworkBest forBridge, pad arm, hinge repairEndpiece and butt jointsWhy Titanium Welding Affects PriceTitanium welds demand dedicated equipment, gas shielding, and welders trained specifically on the material, and rejected joints cannot simply be reworked like steel. This process barrier is a key reason beta titanium and pure titanium lines sit above nickel silver on quotations. You can see the welding and finishing equipment behind these programs on our manufacturing capabilities page, and compare titanium against other materials in our custom optical frames range.Weld strength and finish quality vary by factory. When sourcing titanium frames, ask for joint close-up photos and a bend or drop test report from actual production, not showroom samples.Planning a titanium line?

Question 5

Use factory final QC, a third-party agency such as SGS or QIMA, or both together. Learn how to book the inspection, what to prepare, and when to schedule it.

Accepted Answer

You have three practical routes to inspect frames before shipping: rely on the factory's final QC report, appoint a third-party inspection agency such as SGS, Bureau Veritas, or QIMA to audit the lot on your behalf, or combine both for high-value orders. Whichever route you choose, the inspection is booked once goods are fully produced and mostly packed, and the report you receive becomes your evidence for accepting or rejecting the shipment.Choosing Between the Three OptionsRouteBest forWhat you getFactory final QC reportRepeat programs with a trusted supplierInternal report with photos, defect counts, and packing detailsThird-party inspectionNew suppliers, large lots, regulated marketsIndependent AQL report issued in your name, typically within 24 hoursBoth combinedFirst orders or premium collectionsFactory screening plus an unbiased final verdictHow to Arrange the Inspection, Step by StepPick the agency and standard: choose the inspector and the AQL plan or checklist your contract references.Send the reference pack: approved samples, spec sheets, packaging artwork, and defect examples so the inspector checks the right things.Book the date: most agencies need 2 to 3 working days' notice once goods are 100% produced and at least 80% packed.Attend or go remote: you can visit, or rely on the written report with photos and sampled carton numbers.Decide on the result: accept, ask for rework and a re-inspection, or hold the shipment until issues are fixed.Timing matters: inspect too early and the lot is incomplete, too late and the container is sealed. Agree the inspection window in the purchase contract so cartons stay accessible.READSUN keeps goods accessible for buyer-appointed inspections and supplies its own final QC reports in parallel.

Question 6

AQL inspection is the statistical sampling method for eyewear shipments: draw a random sample, grade defects as critical, major, or minor, and judge against agreed limits.

Accepted Answer

AQL inspection for eyewear is the statistical sampling method used to decide whether a finished shipment passes or fails. Instead of checking every frame, the inspector draws a random sample sized by the lot quantity, grades every defect found as critical, major, or minor, and compares the counts against acceptance limits agreed in your contract. The result is an objective accept, reject, or rework decision that both sides can trust.How an AQL Inspection Runs Step by StepDefine the lot: the shipment quantity is confirmed, and an inspection level from the ANSI/ISO 2859-1 tables sets how many frames get sampled.Draw the sample: frames are selected at random from finished, packed or nearly packed goods, not from a curated carton.Grade every defect: critical defects make the frame unsafe or unsellable, major defects would trigger a customer return, minor defects are small cosmetic issues.Compare and decide: if defects exceed the agreed acceptance numbers for each class, the lot is rejected or reworked; otherwise it ships.Record the evidence: the report logs photos, defect counts, and the sampled cartons so both sides see the same data.Defect Classes in Plain LanguageClassTypical eyewear examplesImpactCriticalSharp edges, broken hinge, lens shatter riskLot fails immediatelyMajorVisible scratch, misaligned temple, coating defectsCounts toward rejection limitMinorSmall marks hidden in wear, slight color shiftCounts at a looser limitThe exact acceptance numbers, usually written as AQL values in the purchase contract, decide how strict each class is. Tightening them improves outgoing quality but raises rework cost, so set them with your supplier before mass production, not after.AQL sampling is statistical: it reduces risk but cannot guarantee a defect-free lot. Combine it with in-line process checks during production for the best control.READSUN runs in-line and final inspections to the AQL plan agreed with each buyer.

Question 7

Look for ISO 9001, ISO 14001, social compliance audits like Sedex or BSCI, and current CE and ANSI test reports. Here is the checklist and how to verify each one.

Accepted Answer

A trustworthy eyewear manufacturer should hold ISO 9001 for quality management, ISO 14001 for environmental management, a social compliance audit such as Sedex/SMETA or BSCI, and current product test reports covering CE, EN ISO 12312-1, ANSI Z80.3, and material safety.

Question 8

Optical frames alone rarely need CE, while sunglasses do under PPE rules and EN ISO 12312-1. See which standards apply and which documents to request before shipping.

Accepted Answer

Most prescription eyeglass frames do not legally require CE certification in the EU, because they are treated as general consumer products rather than regulated devices. Sunglasses and tinted fashion eyewear, however, do need CE marking under the PPE Regulation and EN ISO 12312-1, and safety eyewear has its own stricter requirements. As the importer, you carry the compliance duty, so it pays to know exactly which standard applies to your order.Which Eyewear Categories Need CE MarkingProduct typeCE required?Governing ruleClear prescription frames (no lenses)Generally no directive appliesGeneral product safety rulesSunglasses, fashion tinted eyewearYesPPE Regulation (EU) 2016/425 + EN ISO 12312-1Safety / protective eyewearYes, stricterPPE Regulation, EN 166 familyFrames with special medical claimsCase by caseEU MDR, if medical claims are madeWhat CE Testing Actually CoversFor sunglasses, EN ISO 12312-1 checks lens transmittance categories, UV cutoff at 400 nm, and resistance qualities. For metal frames, nickel release is tested against EN 1811 to protect sensitive skin, and REACH restricts substances such as lead and cadmium. Do not assume a supplier's generic "CE" logo proves any of this happened; the marking is only valid with a test report behind it.Documents to Request Before ShippingTest report: EN ISO 12312-1 results for the exact lens category you order.Declaration of Conformity: signed by the importer or manufacturer, listing the standards applied.Material reports: nickel release for metal parts and REACH screening where relevant.Marking check: CE logo, category mark, and traceability code applied to the product or packaging.CE marking rules change over time, and medical claims can move a frame into the EU MDR. Confirm the current requirements with your notified body or compliance advisor before large orders.READSUN supplies CE and material test reports per program, so the documents match the frames you actually ordered.

Question 9

Injection molding in eyewear melts plastic and injects it into a steel mold to form frames fast and consistently. It suits TR90, kids, sport, and budget lines. READSUN runs injection lines in-house.

Accepted Answer

Injection molding in eyewear is a manufacturing method that melts plastic pellets and injects them into a steel mold to form a frame in seconds. It delivers low cost, high consistency, and fast output, which makes it the standard choice for TR90, kids', sport, and budget frame programs. READSUN runs injection lines alongside its acetate and metal lines, so buyers can mix materials in one order.How Injection Molding Works for FramesMold making: a steel mold is CNC-machined to the exact frame shape.Melting: plastic pellets such as TR90 or PC are heated to a flowable state.Injection: the melted plastic is forced into the mold under high pressure.Cooling: the frame cools and hardens inside the mold, then is ejected.Finishing: gates are trimmed, hinges fitted, and color or coating applied.Pros and Cons at a GlanceAspectInjection MoldingAcetate SheetUnit costLow, ideal for volumeHigher per pieceConsistencyVery high, mold-drivenSmall piece-to-piece variationFeel and depthLighter, simpler finishRich color through the materialRepairabilityHard to rework once moldedCan be re-polished and adjustedBest fitTR90, kids', sport, budget linesPremium and fashion collectionsWhere Injection Molding Fits Your LineInjection frames suit high-volume programs where price and repeatability matter most: children's collections, lightweight TR90 optical frames, and sport styles.

Question 11

Glasses are made in two streams-frames are shaped from acetate, plastic, or metal, and lenses are surfaced, coated, and cut-then assembled. READSUN runs both workflows in one plant.

Accepted Answer

Glasses are made in two parallel streams—frames and lenses—that are later assembled into a finished pair. Frames are shaped from acetate, injected plastic, or metal, while lenses are surfaced, coated, and cut to fit. READSUN runs both workflows in one 20,000 m² plant with 6 production lines and FDA and CE approved processes. Glasses Made Step by Step: The Full Production Process Frame shaping: fronts and temples are made from acetate, injected plastic, or metal. Lens surfacing: lens blanks are ground, polished, and given optical power. Lens coating: anti-reflective, hard, and tint layers are added. Lens cutting: lenses are edged to the exact frame shape. Assembly: lenses are mounted with hinges, screws, and nose pads. Adjustment: temples and fit are aligned for comfort. Final inspection: the pair is checked and packed. Why an Integrated Plant Matters When frames and lenses are made under one roof, lead times and quality stay easier to control. READSUN's integrated plant covers about 20,000 m² with 6 production lines, a monthly output near 500,000 pairs, more than 10 years of OEM and ODM experience, and FDA and CE approvals.

Question 12

Plastic eyeglass frames are made by injection molding: heated plastic is injected into a steel mold, cooled, trimmed, and finished with color. READSUN runs injection lines alongside acetate and metal.

Accepted Answer

Plastic eyeglass frames are made by injection molding: heated plastic is injected into a steel mold, cooled, de-burred, and finished with color or coating. This is different from acetate frames, which are cut from sheet stock rather than molded. READSUN runs injection lines next to its acetate and metal lines, so buyers can mix materials in one order. Plastic Eyeglass Frames: The Full Production Process Mold design: engineers build a CNC-milled steel mold for the frame shape. Injection molding: heated plastic is forced into the mold under pressure. Cooling and ejection: the part cools, then is released from the mold. Deburring: gates and flash are trimmed off the raw frame. Surface finishing: frames are sprayed, plated, or printed for color and feel. Hinge assembly: metal hinges are set and secured to front and temples. Quality check: fit, finish, and screws are inspected before packing. Plastic Injection vs Acetate Sheet Injection plastic and acetate are both "plastic" in everyday language, but they are made differently. Injection frames come from melted plastic in a mold, which is fast and cheap for volume. Acetate frames are cut and polished from colored sheet, which feels richer but costs more per piece. See the equipment behind both on our manufacturing capabilities page. How READSUN Runs Plastic Eyeglass Frames Buyers can start from an existing model or a fresh mold. Explore custom optical frames, review OEM and ODM eyewear services, or read manufacturing capabilities before requesting a quote.

Question 14

Acetate frames are cut from sheet acetate, CNC-milled, hand-polished, hinged, and adjusted, with color through the whole frame. READSUN makes them on dedicated lines.

Accepted Answer

Acetate frames are made from plant-based sheet acetate that is cut, milled by CNC, hand-polished, fitted with hinges, and finally adjusted and inspected. The color runs through the whole sheet, so edges show rich patterns instead of surface paint. READSUN produces acetate frames on dedicated lines using this full process, which keeps both finish and consistency under control.The Acetate Frame Production ProcessSheet selection: pick the acetate color and thickness for the design.Cutting: the sheet is cut into rough frame blanks.CNC milling: machines shape the fronts and temples to spec.Hand polishing: edges are polished to a deep, glossy finish.Hinge fitting: metal hinges are set and secured.Assembly and adjustment: parts are joined and aligned for fit.Inspection: each frame is checked before packaging.Why Acetate Beats Painted PlasticBecause the color is part of the material, acetate frames resist chipping and show unique depth at every angle. The same plant that mills them also runs injection and metal lines, so buyers can mix materials in one order.

Question 19

Pick a real manufacturer, not a trading company: verify the production site, in-house materials, certifications, sample speed and communication. READSUN's factory figures make vetting straightforward.

Accepted Answer

Choose an eyewear factory in China by verifying four things before you commit: that the supplier is a real manufacturer rather than a trading company, that core materials are produced in-house, that quality certifications are current, and that communication stays fast through sampling and production. A factory that welcomes video or on-site audits is usually confident in what happens on its own floor.Eyewear Factory China: A 5-Point Vetting ChecklistAudit the real site: request a live video tour or on-site visit and match it to business license details.In-house materials: factories running their own acetate, metal, or injection lines control quality and schedule better.Certifications: ask for current FDA and CE documents, not just claims on a product page.Sample quality and speed: a paid pre-production sample reveals both workmanship and responsiveness.Communication: fast, precise English replies during sampling predict how production issues get handled.Why Buyers Shortlist READSUNFactory Figures You Can CheckREADSUN runs a 20,000-square-meter factory with 6 production lines and a monthly capacity of 500,000 pairs, holds FDA and CE approvals, and has more than 10 years of OEM/ODM experience.

There is no single fixed MOQ for custom acetate frames — the minimum order scales with how deep your customization goes. Adding your logo to an existing acetate model needs the smallest run, changing colors or materials needs a mid-size order, and fully bespoke shapes require the highest volume because new tooling must be amortized. Confirm your exact design with the factory to get a precise figure.Custom Acetate Frames MOQ: Minimum Order by Customization LevelLogo on an existing acetate model: the lowest entry point, since the frame and tooling already exist.Color or material changes: a mid-range run, because new acetate sheets and color matching add setup work.Fully bespoke shapes: the highest volume, as new molds and tooling must be amortized across the order.How READSUN Structures Custom Acetate OrdersWhat Affects Your MOQSheet consumption, color matching, and multi-color lamination all raise the practical minimum, while standard shapes keep it lower.

Question 24

Standard optical frames usually do not need FDA 510(k) clearance, but prescription lenses, some sunglasses and medical claims may trigger FDA rules. Check the classification and request test reports.

Accepted Answer

Do optical frames require FDA 510(k) clearance? Short answer: In most cases, no. Standard optical frames are generally not classified as medical devices by the FDA, so they usually do not require 510(k) clearance. However, prescription lenses, certain sunglasses, and products with medical claims may fall under FDA rules. Always check the FDA product classification database for your exact product. FDA 510k Optical Frames: What It Means for Eyewear Importers FDA 510(k) is a premarket notification process for medical devices. Optical frames are often treated as general consumer products, not medical devices. That is why many importers do not need 510(k) clearance for frames alone. But the answer can change when you sell a complete pair of glasses or make health-related claims. Prescription lenses, some sunglasses, and safety eyewear may follow different FDA rules. If you are unsure, review the product classification first. Optical frames only: Usually not a medical device and usually no 510(k). Prescription lenses: May be regulated as medical devices. Sunglasses: May need impact resistance and labeling compliance. Medical claims: Can trigger FDA device rules even for frame products. For production and quality context, see Manufacturing Excellence. Required Standards and Test Methods: FDA 510(k)Import paperwork for optical frames Even when 510(k) is not required, other FDA-related checks may still apply. The table below helps B2B buyers separate common product types. Product Type FDA 510(k) Usually Needed? Other FDA Points to Check Optical frames only No General product safety and labeling Prescription eyeglasses May apply Lens classification and prescription rules Sunglasses Usually exempt but regulated Impact resistance, UV claims, labeling Safety glasses Different rules ANSI Z87.1 or EN 166 may apply FDA 510k Optical Frames: Documents and Certificates to Request When you import eyewear into the U.S., ask your supplier for the documents that match your product. This helps you answer customs, retail, and platform questions faster. Material declaration for frame and lens Lens impact resistance test report, if applicable UV protection test report for sunglasses Labeling and instruction documents Nickel release report for metal frames Supplier quality records and inspection reports Regulatory documents for frame imports Buyers can also review about READSUN Optical for quality system and certification support. FDA 510(k) Explained Step by Step Confirm what you are selling: frames only, complete glasses, or sunglasses. Check the FDA product classification database for your product code. See whether the product is exempt from 510(k) or requires premarket notification. Prepare test reports and labeling documents for the U.S. market. Consult a FDA regulatory specialist if your product makes medical claims. FDA 510k Optical Frames: Test Reports and Declaration of Conformity For U.S. importers, test reports often matter more than a generic certificate. Request reports that clearly show the product name, model number, test standard, test date, and lab information. If you sell custom sunglasses, check impact resistance and UV claims carefully. How READSUN Supports FDA 510k Optical Frames for Global Clients READSUN supports eyewear brands and importers with material selection, sample development, quality inspection, and export documentation. We can help you prepare the right questions for your FDA compliance review.

Question 25

Frame durability testing checks hinge fatigue, frame strength, corrosion, sweat, and finish wear. It helps B2B buyers confirm quality and reduce returns before bulk orders.

Accepted Answer

What does frame durability testing involve? Short answer: Frame durability testing involves mechanical, chemical, and visual checks that simulate real-world use. It usually covers hinge fatigue, frame strength, lens rim stability, corrosion resistance, sweat exposure, coating adhesion, and finish wear. The aim is to confirm that eyeglass frames can survive daily handling, shipping, and long-term wear before bulk production. Frame Durability Test: What It Covers for B2B Buyers A frame durability test is not one single test. It is a group of checks designed to show how a frame performs after repeated opening, bending, cleaning, sweating, and transport. For importers and eyewear brands, the results help reduce return risk and support supplier comparison. Hinge fatigue test: Opens and closes the temples thousands of times to check screw, barrel, and spring hinge performance. Eyeglass frame strength test: Applies controlled pressure to temples, bridge, rims, and solder joints. Corrosion and sweat resistance: Tests metal parts for tarnish, peeling, and nickel release risk. Coating and finish adhesion: Checks plating, paint, and polish for flaking or fading. Dimensional stability: Confirms the frame keeps its shape and fit after heat, stress, and handling. These checks are often reviewed alongside factory quality records. Buyers can also review Manufacturing Excellence to understand how production controls affect final frame reliability. Frame Durability Testing: Key Tests and Standards Durability testing should match the frame material, target market, and use case. A metal optical frame, an acetate frame, and a sporty TR90 frame may need different test priorities. Common reference points include ISO 12870, EN ISO 12870, nickel release requirements, and AQL inspection plans.Frame flex and impact testing Test Area What It Checks Why B2B Buyers Care Hinge fatigue test Temple open/close cycles Fewer loose or broken hinges Frame strength test Temple, bridge, rim pressure Lower shipping and use damage Corrosion test Sweat, salt, humidity exposure Better metal frame lifespan Finish adhesion test Plating, paint, polish durability Fewer visual defects and claims Eyeglass Frame Strength Test and Hinge Fatigue Test Explained The eyeglass frame strength test focuses on the frame structure. It checks whether the front, bridge, endpieces, and temples can resist pressure without bending, cracking, or breaking. The hinge fatigue test focuses on movement. It simulates repeated wearing and storage, especially for barrel hinges and spring hinges. For custom projects, buyers should confirm the hinge type before testing. A standard barrel hinge, spring hinge, and hidden hinge may need different pass criteria. If you are developing custom optical frames, ask the factory to document the hinge specification and test method in the sample approval sheet.Hinge fatigue testing in the lab Frame Durability Test: Specifications B2B Buyers Should Confirm Before ordering, confirm these details in writing: Frame material and surface finish Hinge type and expected open/close cycles Coating or plating thickness, if applicable Nickel release requirement for the target market Accepted AQL level and defect definitions Test report format and sample size Frame Durability Testing for Wholesale and Custom Programs For wholesale orders, durability testing helps protect inventory quality and brand reputation. For custom programs, it helps align design intent with factory execution. A frame may look correct in a photo but still fail after repeated hinge movement or sweat exposure. READSUN supports both stock-style and custom development paths. Buyers can combine durability requirements with logo, color, packaging, and material choices through OEM & ODM eyewear services. How READSUN Handles Frame Durability Testing At about READSUN Optical, durability is reviewed through material selection, in-line checks, final inspection, and pre-shipment review.

These may include test reports, material declarations, coating information, nickel release reports, inspection records, and warranty terms. Clear documents help reduce disputes after shipment and make it easier to explain quality to retail partners. Frame Durability Test: MOQ, Lead Time, and Pricing MOQ, lead time, and pricing for durability testing depend on the frame material, test scope, order volume, and whether the frame is stock or custom. Simple hinge and strength checks can often be added to normal inspection. Full third-party testing may require extra samples and time. To get an accurate plan, share your frame type, target market, expected order quantity, and required test standard. Next step: Review custom optical frames or contact READSUN to discuss your durability testing requirements before bulk production.

Question 26

Eyeglass frame samples cost USD 20–150 per piece: stock USD 20–50, ODM USD 50–120, full OEM USD 100–300. Sample fees are usually deducted from bulk orders.

Accepted Answer

How much do eyeglass frame samples cost? Eyeglass frame samples typically cost between USD 20 and USD 150 per piece, depending on material, customization level, and whether a new mold is required. Stock frames are cheapest, ODM modifications cost more, and full OEM samples with new tooling are the most expensive. Most factories deduct the sample fee from the bulk order once the quantity reaches an agreed level. READSUN Optical offers transparent eyeglass frame sample price terms for B2B buyers. Eyeglass frame sample produced by READSUN Optical. Eyeglass Frame Sample Price: Price Ranges by Material and Order Volume The cost of frame samples varies widely. A simple stock acetate frame costs far less than a fully custom titanium frame with a new mold. The table below shows typical ranges by sample type. Sample Type Typical Price Range What It Includes Stock frame sample USD 20–50 Existing model, standard color, no logo ODM modified sample USD 50–120 Existing model + custom color, logo, or material change Full OEM sample USD 100–300+ New design, new mold, hand sample, engineering sample Logo sample USD 50–100 Stock frame + laser engraving or metal logo plate Custom color sample USD 80–150 Custom acetate sheet or metal plating color Material also affects sample fee eyeglasses. Acetate and TR90 samples are usually cheaper than titanium or beta titanium. Metal samples require welding and plating setup, which raises the price. Full OEM samples with a new steel mold are the most expensive because tooling cost is included. What Affects the Total Cost of Eyeglass Frame Sample Price Several factors drive sample price up or down. Understanding each one helps buyers plan the budget and negotiate better terms. Key factors that affect sample price Material: acetate and TR90 are cheaper; titanium and beta titanium are more expensive. Structure: full rim is standard; rimless and semi-rimless require extra drilling and mounting steps. Customization: custom color, custom size, and logo application add cost. Tooling: new mold or CNC template raises the sample price significantly. Sample stage: hand sample, engineering sample, confirmation sample, and pre-production sample each add cost. Quantity: ordering multiple samples of the same model reduces the per-piece cost. Shipping: express courier for samples is fast but adds USD 30–80 per shipment. Compliance testing: nickel release and durability testing add cost if required at sample stage. Buyers should always ask for a written sample quotation that separates tooling cost, sample unit cost, and shipping. This makes comparison between suppliers easier and avoids hidden fees. Side view of a frame sample showing temple and hinge quality. Eyeglass Frame Sample Price: Unit Cost Breakdown The sample price is not a single cost. It combines material, labor, tooling, and shipping. The table below breaks down what buyers are actually paying for. Cost Element What It Covers Typical Share Material Acetate sheet, TR90 resin, titanium wire, metal parts 20–30% Labor Cutting, polishing, assembly, hand finishing 30–40% Tooling / setup Mold, CNC template, plating setup 20–30% (higher for OEM) Logo / branding Laser engraving, stamping, silk printing 5–10% Shipping Express courier for sample delivery 10–20% Compliance testing Nickel release, durability test if required 0–10% For stock samples, tooling cost is zero. For full OEM samples, tooling can account for half the total price. Buyers should confirm whether the tooling cost is separate from the sample fee or included in it. Tooling, Mold, and Sample Costs for Eyeglass Frame Sample Price Tooling and sampling are the largest upfront costs in custom development. Understanding these costs helps buyers plan the budget. Hand sample: made by hand or 3D printed. Fastest and cheapest sample stage. Usually USD 30–80. Engineering sample: made from the actual mold or tooling. Confirms structure and fit. USD 80–200. Confirmation sample: final sample before production. Must match the approved specification. USD 50–150. Pre-production sample: sample from the production line. Confirms consistency before full run. Usually free or low cost. Injection mold: required for TR90 and plastic frames. Cost depends on mold complexity and cavity number. CNC template: required for acetate frames. Lower cost than injection molds. Metal tooling: required for metal frames. Cost depends on structure and hinge design. Sample fees are usually deducted from the bulk order once the quantity reaches an agreed level. Buyers should confirm this policy in writing before paying. Eyeglass Frame Sample Price: Bulk Discounts and Payment Terms Bulk discounts and payment terms affect the total cost of the sample process. Buyers should understand both before committing. Sample fee refund: most factories deduct the sample fee from the bulk order once quantity reaches an agreed threshold. Multiple sample discount: ordering 3–5 samples of the same model usually reduces the per-piece price. Payment terms: samples are usually paid upfront. Bulk orders follow 30% deposit and 70% balance terms. Shipping cost: sample shipping is usually paid by the buyer, but some factories absorb it for large future orders. Tooling ownership: confirm who owns the mold after production. Buyers should clarify this in the contract. Clear sample fee terms reduce risk for both sides. Buyers should always ask for a written quotation that lists sample unit cost, tooling cost, and shipping separately.

Question 27

Custom frame production takes 45–75 days after sample approval for OEM, 30–45 days for ODM, and 7–15 days for stock.

Accepted Answer

What is the production lead time for custom frames? Custom frame production lead time typically ranges from 45 to 75 days after sample approval, depending on the material, structure, and order volume. The full timeline includes order confirmation, sampling, sample approval, bulk production, quality inspection, and shipment preparation. Stock customization is faster at 7–15 days, while ODM modification takes 30–45 days. READSUN Optical provides a written custom frames production time schedule for every order. Custom frame produced within the agreed production timeline. Custom Frames Production Time: A Plain-English Explanation for B2B Buyers Custom frames production time is the total number of days from order confirmation to shipment readiness. It is not a single number. It is the sum of several stages, each with its own duration and decision point. For B2B buyers, production time has three commercial effects: Launch planning: the timeline determines when your collection reaches retail shelves. Inventory cost: longer lead time means more safety stock and higher carrying cost. Peak season risk: production slows during Chinese New Year and peak season, so timing matters. Buyers should treat the timeline as a planning document, not a promise. Each stage should be confirmed in writing with the factory before the deposit is paid. Required Standards and Test Methods: Custom Frames Production Time Production time is tied to the quality process. Faster production should never skip testing or inspection. Buyers should confirm that the following stages remain in the timeline at every speed tier. Production Stage Typical Duration What It Confirms Order confirmation 1–3 days Specification and deposit confirmed Sample development 7–15 days Design and material feasibility Sample approval 3–7 days Buyer sign-off on sample Mold or tooling 15–30 days Steel mold, CNC template, or metal tooling Bulk production 30–45 days Full run with in-process inspection AQL inspection 2–5 days Defect rate confirmed before shipment Packaging and shipment 3–7 days Cartons packed and shipping documents ready Stages overlap in practice. For example, mold making and sample approval often run in parallel. Buyers should confirm which stages can be compressed and which cannot. Custom Frames Production Time: Documents and Certificates to Request A production schedule is only useful if it is documented. Buyers should request the following documents before placing a bulk order. Written production schedule: each stage with start date and end date. Sample approval record: confirms the sample matches the specification. AQL inspection report: confirms the defect rate before shipment. Test reports: hinge fatigue, salt spray, nickel release as relevant. Material declaration: confirms material grade and source. Shipping documents: packing list, commercial invoice, and bill of lading. Delay clause: confirms compensation or penalty if production runs late. Buyers should verify that the production schedule matches the actual order quantity. Some factories quote a fast lead time but apply it only to stock orders, not custom production. Side view of frame produced within the agreed timeline. Custom Frames Production Time Explained Step by Step Buyers can plan a custom frame project using a five-step timeline framework. This keeps the schedule clear and comparable across suppliers. Confirm the order. Specification, price, deposit, and target shipment date agreed in writing. Approve the sample. Buyer signs off on the confirmation sample before mold or bulk production starts. Start tooling and bulk production. Mold making and production run in sequence with in-process inspection. Pass AQL inspection. Defect rate confirmed against AQL 2.5/4.0 standard before shipment. Ship and confirm arrival. Shipping documents prepared and shipment arranged with the buyer's forwarder or our own. This framework prevents surprises. Buyers should always ask for the written schedule in the purchase agreement, not just a verbal estimate. Custom Frames Production Time: OEM Production Timeline The table below shows a typical OEM production timeline for different order types. Actual timing depends on material, structure, and factory load. Order Type Sample Time Production Time Total Lead Time Stock customization 3–7 days 7–15 days 10–22 days ODM modification 7–15 days 30–45 days 37–60 days Full OEM development 15–30 days 45–75 days 60–105 days These ranges are a guide, not a fixed rule. Chinese New Year, summer peak season, and material shortages can add 10–20 days. Buyers should always plan a buffer of at least two weeks for critical launches. Custom Frames Production Time: Cost and Timeline Impact Production time affects cost in several ways. Buyers should understand the trade-offs before choosing a fast or slow production path. Expedited production: some factories offer fast-track production at 10–20% surcharge, subject to line availability. Air freight: faster shipping but higher cost; suitable for small urgent orders. Sea freight: lower cost but longer transit; best for large orders planned well in advance. Peak season: production and shipping costs rise during Q3 and Q4, and lead times extend. Buffer stock: buyers planning around lead time may need to hold extra inventory, which adds carrying cost. Buyers should balance speed against cost. A slightly longer lead time with sea freight is often better than air freight on a large order, unless the launch date is fixed.

Bulk order frames produced by READSUN Optical with tiered pricing. Bulk Order Discount Eyewear: What B2B Buyers Need to Know A bulk order discount is a price reduction based on order quantity. For eyewear factories, higher volume means fixed costs such as mold setup, color mixing, and packaging design are spread across more pieces. That cost saving is passed back to the buyer as a lower unit price. For B2B buyers, tiered pricing has three commercial benefits: Lower unit cost: the larger the order, the lower the price per frame. Better margin: lower cost means higher profit at the same retail price, or a more competitive wholesale price. Priority production: large orders often get scheduled first, especially during peak season. Discounts are not automatic. Buyers should confirm the tier structure in writing before placing an order. A factory that gives vague answers about volume pricing is likely to surprise the buyer later with hidden costs. Required Standards and Test Methods: Bulk Order Discount Eyewear Volume pricing is tied to quality standards. A lower unit price should never mean lower material grade or weaker quality control. Buyers should confirm that the following tests still apply at every volume tier. Quality Check Applies at All Volume Tiers Why It Matters AQL inspection Yes — same standard at 300 pcs or 3,000 pcs Prevents defect rate from rising with volume Hinge fatigue test Yes Confirms hinge quality does not drop at scale Salt spray test Yes — for metal frames Confirms plating quality at every volume Nickel release test Yes — for regulated markets Required for EU and other markets regardless of volume Material declaration Yes Confirms material grade at every tier Batch traceability Yes Confirms the shipment matches the agreed specification Some factories offer a lower price by cutting material grade, plating thickness, or inspection level. Buyers should always ask what changes at each price tier and confirm the answer in writing. Bulk Order Discount Eyewear: Documents and Certificates to Request A clear discount structure should come with clear documentation. Buyers should request the following documents before signing a bulk order agreement. Written price list: unit price at each volume tier, with clear definitions. MOQ per model and per color: confirms the minimum for each SKU. Mixed-model rules: confirms whether models and colors can be combined for the tier. AQL inspection report: confirms defect rate for the actual production batch. Test reports: hinge fatigue, salt spray, nickel release as relevant. Material declaration: confirms material grade and source. Payment terms: deposit percentage, balance terms, and any credit options. Shipping terms: FOB, CIF, or EXW, and who pays for freight. Buyers should verify that the discount tier matches the actual quantity ordered. Some factories apply the higher tier only to the quantity above the threshold, not to the entire order. This should be clarified in the quotation. Side view of frame produced under bulk pricing with full quality checks. Bulk Order Discount Eyewear Explained Step by Step Buyers can negotiate bulk discounts using a five-step framework. This keeps the discussion clear and comparable across suppliers. Confirm the tier structure. Ask for the price at 300, 500, 1,000, and 3,000 pieces. Some factories add a 5,000-piece tier for very large orders. Check whether tiers apply to the full order or only the excess. Some factories apply the lower price to the entire order once the threshold is reached. Others apply it only to the quantity above the threshold. Confirm mixed-model rules. Many factories allow mixed models and colors to reach the tier, as long as each model meets its own MOQ. Ask about negotiable items. Freight, packaging, and payment terms are often negotiable in addition to the unit price. Confirm quality standards. A discount should not reduce AQL level, material grade, or test requirements. This framework prevents misunderstandings. Buyers should always ask for the quotation in writing with each tier clearly listed. Bulk Order Discount Eyewear: Volume Discount Eyeglass Frames The table below shows a typical tier structure for volume discount eyeglass frames. Actual pricing varies by material, structure, and logo customization. Order Quantity Typical Discount Range Notes 300–499 pcs Base price Entry-level tier; suitable for new brands and test orders 500–999 pcs 3–5% off base price Common tier for growing brands 1,000–2,999 pcs 5–10% off base price Best tier for established brands and distributors 3,000+ pcs 10–15% off base price Large order tier; may include priority production These ranges are a guide, not a fixed rule. Actual discount depends on material, structure, customization, and the factory's current production load. Buyers should always negotiate with specific quantity targets and get the price list in writing. Bulk Order Discount Eyewear: Cost and Timeline Impact Bulk discounts affect both unit cost and production timeline. Buyers should plan for both when placing large orders. Unit cost: drops as quantity increases because fixed costs are spread across more pieces. Production lead time: larger orders take longer to produce, but often get priority scheduling. Payment terms: large orders may qualify for more flexible terms, such as extended balance periods or partial credit. Shipping cost: larger orders reduce per-unit freight cost, especially for sea shipments. Inventory risk: larger orders require more storage and carry more risk if the design does not sell. Buyers should balance the discount benefit against the inventory risk. A slightly higher price at a smaller quantity may be better than a deep discount on a large order that does not sell.

Question 29

Standard frame defect rate is AQL 2.5 for major defects and AQL 4.0 for minor defects. Premium orders may use AQL 1.5. Batches above the limit are rejected or reworked.

Accepted Answer

What is an acceptable defect rate for frames? An acceptable defect rate for eyeglass frames depends on the AQL level agreed between buyer and factory. For most wholesale orders, AQL 2.5 for major defects and AQL 4.0 for minor defects is the industry standard. This means a batch is acceptable if the sample shows defects below those limits. Anything above is rejected or subject to negotiation. READSUN Optical applies AQL 2.5/4.0 inspection to every order and provides full inspection reports for each shipment. Frame inspection under READSUN's AQL 2.5/4.0 defect control system. Eyeglass Frame Defect Rate: What It Means for Eyewear Importers The eyeglass frame defect rate is the percentage of frames in a batch that fail to meet the agreed quality standard. It is not a fixed number. It is defined by the AQL level agreed in the purchase order and measured through sampling inspection. For B2B buyers, the defect rate affects three commercial outcomes: After-sales cost: higher defect rates mean more returns, replacements, and warranty claims. Retail relationships: optical chains and distributors expect consistent quality. Brand reputation: repeated quality issues damage trust with end customers. Defect rates are measured in two categories: major defects and minor defects. Major defects affect function or safety, such as a broken hinge or sharp edge. Minor defects affect appearance only, such as a small surface scratch. Each category has its own AQL limit. Required Standards and Test Methods: Eyeglass Frame Defect Rate Defect rate measurement follows the AQL sampling standard. The table below shows the common AQL levels used in eyewear production and what each level means for the shipment. AQL Level Typical Application Buyer Expectation AQL 1.5 Premium frames, high-end retail Very low defect tolerance; strict inspection AQL 2.5 Standard wholesale frames, major defects Accepted industry standard for most orders AQL 4.0 Standard wholesale frames, minor defects Moderate tolerance for cosmetic issues AQL 6.5 Promotional frames, low-cost lines Higher tolerance; lower price point For most B2B eyewear orders, the standard is AQL 2.5 for major defects and AQL 4.0 for minor defects. This balance allows factories to produce at reasonable cost while keeping serious quality problems under control. Eyeglass Frame Defect Rate: Documents and Certificates to Request Buyers should request inspection documents before shipment. These documents confirm the actual defect rate of the batch and support customs clearance and after-sales claims. AQL inspection report: shows the sample size, defect count, and pass/fail result. Defect classification sheet: lists major and minor defect categories used in the inspection. Batch production records: confirms the production date and batch number. Test reports: hinge fatigue, salt spray, and nickel release as relevant. Material declaration: confirms material grade and source. Declaration of conformity: confirms the product meets the destination market rules. Replacement / credit policy: defines the remedy if the batch fails inspection. Buyers should verify that the AQL inspection report references the exact shipment batch. A report from an earlier batch is not valid evidence of current quality. Side view inspection of hinge and temple quality under AQL sampling. Eyeglass Frame Defect Rate Explained Step by Step Buyers can understand defect rate control in five simple steps. This helps when reviewing AQL inspection reports and negotiating with the factory. Agree on the AQL level. Standard is AQL 2.5 for major defects and AQL 4.0 for minor defects. Premium orders may use AQL 1.5. Define major and minor defects. Major defects affect function or safety. Minor defects affect appearance only. Choose the sample size. AQL tables define how many pieces to inspect based on the batch size. Run the inspection. The inspector counts defects in the sample and compares them with the acceptance number. Decide pass or fail. If defects are below the limit, the batch is accepted. If above, the batch is rejected or subject to rework. This process makes quality measurable. It also gives both sides a clear basis for resolving disputes. A factory that resists AQL inspection or gives vague answers about defect rates is a red flag. Eyeglass Frame Defect Rate: Test Reports and Declaration of Conformity Test reports support defect rate control by confirming the durability and compliance of the batch. Buyers should request reports for the exact batch being shipped. Common test reports include: Hinge fatigue test report: confirms hinge durability over thousands of cycles. Salt spray test report: confirms plating resistance to corrosion. Nickel release test report: confirms EU REACH compliance. Drop test report: confirms frame durability under normal handling. AQL inspection report: confirms the actual defect rate of the batch. Material declaration: confirms the material grade and source. Buyers should match the report date and batch number with the actual shipment. This prevents factories from using old test reports for new production. A reliable eyeglass frame manufacturer will provide these documents for every order.

Question 30

Wholesale eyeglass frames typically carry a 12-month warranty covering hinge failure, weld breakage, plating peeling, and structural cracks. Excludes accidental damage and normal wear.

Accepted Answer

What is the warranty on wholesale eyeglass frames? Most wholesale eyeglass frames carry a 12-month warranty from the date of shipment, covering manufacturing defects such as broken hinges, loose welds, plating failure, and structural cracks. The warranty does not cover accidental damage, normal wear, or improper use. Claim terms, coverage scope, and replacement policy should always be written into the purchase agreement. READSUN Optical offers a standard 12-month eyeglass frame warranty with a clear claim process for B2B buyers. Wholesale eyeglass frame covered by READSUN's 12-month warranty. Eyeglass Frame Warranty: What It Means for Eyewear Importers An eyeglass frame warranty is a written commitment from the factory to replace or compensate for frames that fail due to manufacturing defects within a defined period. For B2B buyers, the warranty is not only a quality promise. It is a cost-protection tool that reduces after-sales risk and protects brand reputation. A proper warranty has three commercial effects: Predictable after-sales cost: buyers can plan for warranty claims instead of facing unexpected losses. Clear dispute process: a written policy avoids arguments about who is responsible for defects. Stronger retail relationships: optical chains and distributors prefer suppliers who stand behind their products. Warranty terms vary widely between factories. Some offer no written policy. Others offer 6, 12, or 24 months. Buyers should always confirm coverage in writing before placing a bulk order. Required Standards and Test Methods: Eyeglass Frame Warranty A warranty is only meaningful if the product is tested against clear standards. Buyers should confirm that the factory runs the following tests before shipment. These tests support the warranty promise and reduce the risk of claims. Test What it confirms Warranty relevance Hinge fatigue test Hinge survives thousands of open-close cycles Supports hinge warranty claims Weld strength test Welds hold under pulling force Supports frame breakage claims Salt spray test Plating resists corrosion from sweat and humidity Supports plating failure claims Nickel release test Nickel release stays below EU REACH limits Supports allergy-related claims Drop test Frame survives normal handling Supports structural durability claims Dimensional stability test Frame keeps its shape under heat Supports warping claims Without these tests, a warranty becomes difficult to enforce. Buyers should request test reports for the exact batch being shipped, not just a sample report from an earlier production run. Eyeglass Frame Warranty: Documents and Certificates to Request A written warranty package protects both the buyer and the factory. Buyers should request the following documents before signing a purchase agreement. Written warranty policy: coverage period, covered defects, and exclusions. Claim process document: how to submit a claim, required evidence, and response time. Test reports: hinge fatigue, weld strength, salt spray, nickel release, and drop test. AQL inspection report: confirms the defect rate before shipment. Material declaration: confirms the material grade and source. Declaration of conformity: confirms compliance with the destination market rules. Replacement policy: confirms whether the factory replaces, refunds, or provides credit. Buyers should verify that the warranty policy references the exact product and batch. A generic warranty without a batch reference is harder to enforce in a dispute. Side view showing hinge and temple covered by the frame warranty. Eyeglass Frame Warranty Explained Step by Step Buyers can evaluate any warranty offer using a five-step framework. This keeps the comparison consistent across suppliers. Check the coverage period. Standard is 12 months from shipment date. Some factories offer 6 months; premium suppliers offer 24 months. Confirm covered defects. Hinges, welds, plating, structure, and dimensional stability should be covered. Normal wear is not. Read the exclusions. Accidental damage, misuse, improper lens fitting, and unauthorized repair are usually excluded. Review the claim process. Buyers should know how to submit a claim, what evidence is required, and how fast the factory responds. Confirm the remedy. The factory may replace, refund, or issue a credit note. Buyers should know which applies to which defect type. This framework avoids confusion later. A warranty that looks generous on paper may have strict exclusions. A shorter warranty with clear terms is often better than a long warranty with vague language. Eyeglass Frame Warranty: Test Reports and Declaration of Conformity Test reports support the warranty by proving that the product was inspected against agreed standards. Buyers should request reports for the exact batch being shipped. Common test reports include: Hinge fatigue test report: confirms the hinge can survive thousands of cycles. Weld strength test report: confirms weld durability for metal frames. Salt spray test report: confirms plating resistance to corrosion. Nickel release test report: confirms EU REACH compliance. Drop test report: confirms frame durability under normal handling. Dimensional stability test report: confirms the frame resists warping. Buyers should match the report date and batch number with the actual shipment. This prevents factories from using old test reports for new production.
