The role of the injection system

Injection system is one of the most important components of injection molding machine. Generally, there are three main forms of plunger type, screw type and screw pre-plastic plunger injection type. The most widely used is the screw type. The function is that, in a cycle of the injection molding machine, a certain amount of plastic can be plasticized and plasticized in a predetermined time, and the molten plastic is injected into the mold cavity through the screw at a certain pressure and speed. After the injection is completed, the melt injected into the cavity is kept set.
