Production technology of high-grade frames and high-grade sunglasses

(1) PC group process: invoicing → documentary → invoicing.

(2) Design group process: design and development → drawing → multicolor.

(3) Handboard assembly process: CNC machining → carving → manufacturing the handboard according to the drawing requirements.

(4) Winding process: eye core (blue film) → winding → delivery.

(5) Hydraulic assembly process of accessories: heat-treat hydraulic die (stainless steel, which is not easy to soften when heated by oil) → grinding die → grinder → mold opening → material test → wire drawing → bending → oil pressure → trimming → barrel rolling.

(6) Small punching process of fittings: filing → fitting processing 【 milling machine, drilling machine and manual die cutting machine (twisting) 】→ welding → framing → barrel rolling → polishing →QC (equivalent to the inspection department).

(7) Welding group process:

A) Burn the jaws (full frame) → Gong jaws → Burn the bridge of the nose → Burn the beams → Burn the pipes → Burn the hinges → Burn the slingshot shell → Add silver (beneficial to welding) → Burn the frame.

B) The process of burning the bridge of the nose: Cheyan nucleus → Gong bridge of the nose (60%)→ burning the bridge of the nose → grinding (rubbing the spleen when twisting) → burning the tube.

(8) The assembly process of rubber parts: (including making foot sleeves, rubber proportioning and rubber decorative materials) Documentary → Cutting (155mi)→ Making proportioning → Clamping → Copper wire → Gong proportioning → Car proportioning fancy → Manual → Tail bending proportioning → Glue application (when hinged) → Cutting proportioning → Foot sleeves → Piercing → Drum rolling.
