The mold is a tool used to form objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article by changing the physical state of the formed material. According to the different materials formed, the mold can be divided into metal molds and non-metal molds. Metal molds are divided into: casting molds (nonferrous metal die casting, steel casting), and forging molds; non-metal molds are also divided into: plastic molds and inorganic non-metal molds. According to the different materials of the mold itself, the mold can be divided into: sand mold, metal mold, vacuum mold, paraffin mold and so on. Among them, with the rapid development of polymer plastics, plastic molds are closely related to people's lives. Plastic molds can be generally divided into: injection molding molds, extrusion molding molds, gas-assisted molding molds, etc.
