Manufacturing Process

  • Eyeglass Acetate Processing

    The sheet material is resistant to deformation, has stable color, and is comfortable to wear for extended periods. Optimized hot-pressing process reduces warping and cracking, achieving a premium feel.

    Differentiated Advantages

    • Natural texture

    • Hot-bending to fit facial curves

    • Capable of multi-layered composite colors or gradient textures

    Quality standards

    • CNC cutting

      Millimeter-level precision cutting of sheet metal lays the foundation for subsequent processing.

    • Baking

      Slow baking removes moisture, increases hardness, and reduces deformation.

    • CNC machining

      Precision machining of the front contour and edges ensures consistent dimensions.

    • Rim Bending

      The sheet material is heated and bent to form the outline of the picture frame.

    • Nose & Temple Shaping

      Adjust the angle and curve to ensure an ergonomic fit.

    • Tumbling

      Millimeter-level precision cutting of sheet metal lays the foundation for subsequent processing.

    • Hinges

      Precise drilling and automatic nailing ensure a stable structure.

    • Micro-carving

      Intricate pattern engraving enhances brand recognition and aesthetic appeal.

    • Polishing

      Hand-polished multiple times, resulting in a mirror-like finish and a delicate touch.

    • Cleaning

      Ultrasonic cleaning removes minute residues and ensures a clean surface.

    • Lens Groove

      Automatic grooving ensures precise lens fit.

    • QC & Packaging

      Multiple inspections ensure that each frame meets precision and manufacturing standards.
