Acetate eyeglasses fine carving CNC workshop


   Cellulose acetate sheets undergo precision CNC milling to create eyewear frames, beginning with digital template programming.   The CNC machines execute high-accuracy cutting for frame shapes and intricate engravings, followed by automated bevelling and groove-cutting for hinge mechanisms.
TR90eyewearmold pressing workshop

   Thermoplastic TR-90 pellets are injection-molded using precision temperature-controlled presses.Custom stainless molds with cavity cooling channels shape frames via hydroforming, achieving <0.1mm dimensional accuracy.  Robotic arms transfer semi-molten material into multi-stage compression molds for temple core reinforcement. Infrared pre-heating ensures uniform material flow before injection-overmolding for metal alloy integrations.Post-curing involves 12-hourcontrolled cooling to stabilize molecular structure.           Automated demolding with anti-stick coatings minimizes surface defects.
Metal Eyewear Welding Process



   Metal frames (stainless steel or titanium) are joined using precision welding techniques. Components undergo surface cleaning and alignment before spot welding or laser welding secures hinges and joints. Apply controlled heat (800-1,200°C) to fuse materials without distortion.

Metal Eyewear Polishing Process


   Post-weld grinding and polishing ensure smooth transitions, followed by anti-corrosion treatments. Quality checks include joint strength testing and visual inspections for seamless finishes.
