In the process of plastic processing, molds are needed. Molds are a tool for producing plastic products and also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain parts with complex shapes. Specifically, it refers to injecting the heated and melted material into the mold cavity under high pressure, and obtaining a molded product after cooling and solidification.
