Custom Women Round Frame Polarized UV400 Acetate Sunglasses with Metal Pin





A round acetate sunglass frame with a polarized UV400 lens lenses, hand-polished and built for a women fashion collection.
Overview
SA290040 is a round sunglass frame cut from acetate sheet sheet and finished by hand. Acetate is not injected: the front is milled from a block, tumbled for hours, then polished on a wheel, which is why the colour has depth rather than sitting on the surface. The metal pin is set into the front after polishing rather than moulded in, so the joint stays flush and the pin does not sit in a halo of stressed material. The result is a frame with a heavier, more deliberate feel than a moulded plastic equivalent, and a lustre that survives daily wear.
integrated acetate nose pads and a reinforced hinge The lens is a polarized UV400 lens, cut to the rim profile and mounted without a gap. Nose pads are integrated into the front on this model, so there is no separate pad arm to bend out of shape, and the fit stays consistent across a production run.
The frame is supplied for wholesale and OEM programmes with MOQ: Confirmed at quotation stage. The round front is milled from a 6 mm sheet, which gives the rim enough depth to hold a polarized lens without a visible edge at the bevel. Colours can be matched to a reference chip, and the metal detail, lens tint and temple core can all be specified per market. Cut as a custom women round frame, the round frame front is milled from acetate sheet and fitted with polarized uv400 lenses, while a metal pin at the temple adds the detail that separates an acetate sunglasses line from a plain one; the metal pin is inserted after polishing so the line stays clean.
Key Features
Hand-Polished Acetate
Acetate sheet is milled, not moulded, so the frame can carry layered and translucent colourways that injection plastic cannot reproduce. After milling, the frame is tumbled in wood chips and polished on a cotton wheel, which closes the surface and gives the deep gloss associated with premium eyewear. The process is slower, and the difference is visible in the hand.
Metal Detail and Hinge
Construction detail: integrated acetate nose pads and a reinforced hinge. The hinge is a metal barrel seated into a milled pocket, reinforced with a rivet where the temple meets the front, so the fold stays tight after repeated use. Decorative metal pins are inserted after polishing and locked in place, giving a clean line without visible adhesive.
Lens and UV Performance
The lens is a polarized UV400 lens, cut and edged to the rim and checked for centration before mounting. UV400 protection is verified on a transmission meter as part of final inspection, and the lens is seated with even compression so it does not craze at the edge. Tints, gradients and mirror coatings are available on request.
Fit and Finish Options
Front width, bridge and temple length are set for the women fit, with a slight pantoscopic tilt so the frame sits correctly on the cheek. Temple tips can be laser-marked, and the inside of the temple carries the model and size. Custom colourways are matched from a chip or a physical sample.
Product Showcase
The photographs below show SA290040 from the front, in three-quarter view and at the temple, where the hinge, the metal detail and the polished edge are visible. Colour depth in acetate only reads under raking light, so the side views are the ones to study. The metal pin is inserted after polishing, so the joint stays flush rather than sitting in a halo of stressed material.

Acetate is a sheet material, so colour and thickness are fixed per colourway and quoted with the order. Lens specification, metal detail and temple length that are not listed above are confirmed at quotation stage.
OEM & ODM Customization
Customisation on an acetate frame goes further than colour. The front can be milled to a new profile from a drawing, the temple core can carry a pattern, the metal pins can change position, and the lens can be specified by tint, gradient or mirror. Send the reference and the artwork, and we return a specification sheet plus a colour chip before the sheet is cut. Our OEM and ODM optical frames page describes the process.
- Colour matched to Pantone, RAL or a physical chip, with a moulded or plated dip approved before bulk.
- Logo by pad print, laser engraving or a fixed metal plate, positioned on the temple or the lens corner.
- Lens pairing in clear demo, blue-light filter, polarized, photochromic or tinted versions, cut to the frame groove.
- Size grading across two or three age bands, or width options for adult fits, from one mould family.
- Retail packaging: polybag, microfibre pouch, hard case, printed sleeve, barcode and price labelling.
- Artwork and dieline review before mass production, so the frame and the pack are approved in one round.
Sampling and tooling questions are normally settled in one round when the drawing and the colour reference arrive together; the rapid prototyping page explains how a drawing becomes a wearable sample.
Manufacturing & Quality Control
Acetate hides nothing: a flaw inside the sheet appears after polishing, and a hinge seated a fraction off shows as a gap at the brow. The four checks below are sequenced so those faults are caught while the frame can still be corrected.
1. Sheet and Component Inspection
Acetate sheet is checked for colour consistency, internal bubbles and thickness before cutting, since a void inside the block only appears after polishing. Hinges, rivets, metal pins and lenses are inspected for dimension and coating quality, and sheet lots are tagged so a colour complaint can be traced to a batch.
2. Milling, Tumbling and Assembly
Fronts are milled on CNC centres from the approved drawing, then tumbled to remove tool marks before polishing. Hinges are seated and riveted, temples are fitted, and the frame is closed to check the fold angle and the gap at the brow. Dimensional checks cover lens width, bridge and temple length.
3. Polishing and Lens Mounting
Polishing is done in stages, with the frame cleaned between wheels to avoid carrying grit into the surface. Lenses are mounted after polishing, checked for centration and edge gap, then measured on a UV transmission meter. Frames are inspected under daylight-balanced light for scratches, haze and colour drift between front and temples.
4. Packing and Batch Audit
Each frame is sleeved, cased and counted against the order breakdown, with the lens specification confirmed on the label. Sampling covers hinge cycles, lens seating, logo position and carton marking. A retained frame from each colour is archived so repeat orders can be matched against the original.
Applications
- Fashion sunglass brands building a seasonal acetate story.
- Optical boutiques that sell sun as an accessory alongside prescription.
- Duty-free and travel retail buyers wanting a high perceived-value frame.
- Online retailers with a design-led, mid-to-premium assortment.
- Distributors supplying concept stores and department counters.
- Private label programmes needing a distinctive silhouette.
Acetate rewards buyers who plan colour ahead: sheet is ordered per colourway, so the palette is usually locked with the purchase order rather than after it. The round front is milled from a 6 mm sheet, which gives the rim enough depth to hold a polarized lens without a visible edge at the bevel.
The rest of the acetate and metal sun range is in the women's sunglasses collection. Buyers planning a seasonal story usually lock the palette with the purchase order, because sheet is ordered per colour rather than per unit.
FAQ
What is the MOQ and can colours be mixed?
MOQ is Confirmed at quotation stage. Colours can be mixed within the order, but sheet is purchased per colour, so each colourway needs to meet its own minimum. The palette is normally confirmed with the purchase order so the material can be booked against the production slot.
Can we specify the lens tint and coating?
Yes. Solid tints, gradients, mirror coatings and polarized options are available, and UV400 performance is verified on a transmission meter before packing. The lens specification is confirmed at quotation because it drives both cost and the labelling required in the destination market.
How is the frame branded?
Temple marking by laser or hot stamp, metal logo plates, and engraved core wires are all possible. Because acetate is polished after milling, branding is applied at a defined stage in the process, and the artwork is approved before that stage begins.
