Plastic Injection Molding Case Study—Connector project

Plastic Injection Molding Case Study—Connector project

Challenge of product:

• 1. Very tiny tolerance: most of tolerance on the drawing are between
  +/0.03mm~+/-0.05mm.
• 2. The thickness of all ribs are 0.3~0.34mm, and the depth are 15.4mm
• 3. No burr on the all shut off areas.

Mold solution:

• 1. We must control the mold tolerance to ensure the product tolerance: +/-0.001mm by grinding, most of the inserts finished by grinding, +/-0.005mm by EDM, only EDM the areas which unable to process by grinding.
• 2. We used high grand steel, all insert are made by Viking.
• 3. Parts need to be molded on high speed injection Machine. You can only fill full 0.3mm*depth15mm areas on the part by using high-speed injection molding machine like Fanuc
