PLASTIC INJECTION MOLDING PROCESS

1. Raw material preparation: Select appropriate plastic raw materials for drying, color matching and other pretreatment.

2. Mold design: Design mold according to product requirements to ensure product size, shape and accuracy.

3. Injection molding: the molten plastic raw materials are injected into the mold, and the required products are obtained through cooling and curing.

4. Post-treatment: trimming, polishing, painting and other post-treatment of injection products.
