Injection molding machine is the main molding equipment that uses plastic molding molds to make thermoplastic or thermosetting materials into plastic products of various shapes.
Function of injection system: injection system is one of the most important components of injection molding machine. Generally, there are three main forms: plunger type, screw type and screw pre plastic plunger injection type. The most widely used is screw type. Its function is to heat and plasticize a certain amount of plastic within a specified time in a cycle of the injection molding machine, and then inject the molten plastic into the mold cavity through the screw under a certain pressure and speed. After the injection, the molten material injected into the mold cavity shall be kept in shape.
