An injection molding machine, also known as an injection molding machine or an injection machine, is a main molding device for making thermoplastic plastics or thermosetting plastics into plastic products of various shapes by using a plastic molding mold, and is divided into a vertical type, a horizontal type and a full-electric type. The most widely used at present is the screw type. The function of the injection molding machine is that after a certain amount of plastic is heated and plasticized in a specified time in one cycle of the injection molding machine, the molten plastic is injected into a mold cavity through a screw at a certain pressure and speed. After injection, the melt injected into the mold cavity remains set.
