Background

An injection molding machine is also known as an injection molding machine or an injection machine. It is a main forming equipment for making various shaped plastic products from thermoplastic plastics or thermosetting plastics by using plastic forming mould. The device is divided into a vertical type, a horizontal type and a full-electric type. The injection molding machine can heat the plastic, apply high pressure to the molten plastic, make it inject out and fill the die cavity, the function of the injection system: the injection system is one of the most important components of an injection molding machine, and generally has 3 main forms of plunger type, screw type and screw pre-molding plunger injection type. The most widely used 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.
