In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts. The processing of the appearance of an article is realized mainly through the change of the physical state of a formed material. The product is called 'industrial mother' and injection molding is a method for producing and molding industrial products. The products are generally produced by rubber injection molding and plastic injection molding. The injection molding can be classified into injection molding and die casting. An injection molding machine (an injection machine or an injection molding machine for short) is a main molding device for making thermoplastic plastics or thermosetting plastics into plastic products with various shapes by using a plastic molding die, and the injection molding is realized by the injection molding machine and the die.
