Mold composition


Although the structure of the mold may vary due to the variety and performance of the plastic, the shape and structure of the plastic product, and the type of the injection machine, the basic structure is the same. The mold is mainly composed of a pouring system, a temperature control system, a molded part and a structural part. The gating system and the molded parts are in direct contact with the plastic and change with the plastics and products. They are the most complex and most varied parts in the mold and require the highest finish and accuracy of the part.


The injection mold consists of two parts: the moving mold and the fixed mold. The moving mold is installed on the moving mold of the injection molding machine, and the fixed mold is installed on the fixed mold of the injection molding machine. During the injection molding, the movable mold and the fixed mold are closed to form a casting system and a cavity. When the mold is opened, the movable mold and the fixed mold are separated to remove the plastic product. In order to reduce the heavy mold design and manufacturing workload, most of the injection molds use standard mold bases.
