[0002] Injection molding machine (abbreviated as injection machine or injection molding machine) is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting materials. Injection molding is achieved through injection molding machines and molds; plastic injection molding is a method of plastic products, in which molten plastic is injected into plastic product molds under pressure, and then cooled and molded to obtain the desired plastic parts; there are mechanical injection molding machines specifically used for injection molding; the most commonly used plastic at present is polystyrene;
