Brief introduction of injection molding

Mold injection molding is a processing method used for mass production of certain complex shaped parts. The specific principle means that the heated and melted plastic raw material is injected into the cavity of the plastic mold by the injection molding machine screw at high pressure, and after cooling and curing, the plastic formed product is obtained.

The plastic mold consists of two parts: the moving mold and the fixed mold, the moving mold is mounted on the moving template of the injection molding machine, and the fixed mold is mounted on the fixed template of the injection molding machine. During injection molding, the moving mold and the fixed mold are closed to form the pouring system and cavity, and when the mold is opened, the moving mold and the fixed mold are separated in order to take out the plastic products.

Although the structure of the mold may vary depending on the variety and properties of plastics, the shape and structure of plastic products and the type of injection machine, the basic structure is the same. The mold is mainly composed of pouring system, temperature control system, molding parts and structural parts.
