The mold for injection molding of plastic parts is generally called an injection mold. Injection molds are mainly used for the molding of thermoplastic products, but in recent years they are increasingly used for the molding of thermosetting plastic products. This is a large class of plastic molds with a wide range of applications, large proportions, mature technical conditions and outstanding status. Due to the material or plastic structure or molding process, there are thermoplastic injection molds, thermosetting plastic injection molds, structural foam injection molds, reaction molding injection molds, and no-flow injection molds.
The mold used for continuous extrusion molding of plastic is commonly called extrusion die, commonly known as the head, referred to as the die. This is another type of plastic mold that has a wide range of uses and a wide variety. Extrusion molds are mainly used for molding of plastic pipes, films, materials, monofilaments, flat yarns, packing belts, extruded nets, sheets (sheets), profiles, granulation, cable coatings; For the forming of parisons, such molds are called parison extrusion molds.
The tubular parison which is still plasticized in the extrusion or injection molding is placed in the cavity of the mold and immediately puts compressed air into the tubular parison, so that the parison expands and adheres to the mold cavity. After cooling and hardening, a hollow product can be obtained. The mold used in the molding method of such plastic products
