Plastic Injection Molding / Plastic Tooling

Plastic injection molding is mainly a processing method in which high-temperature molten plastic materials are injected into the mold cavity of the product with high pressure, and after cooling and solidification, the finished product is obtained. It can be used to produce large quantities of plastic parts with complex sizes and shapes.

Plastic Injection Molding Process

The plastic injection molding process is to add the plastic raw materials into the feeding barrel of the injection machine to heat and dissolve, and use high pressure to inject the plasticized raw materials into a lower temperature closed mold cavity, after a certain period of cooling and shaping, the finished product is taken out.
