Injection system

The role of injection system: Injection system is one of the most important part of injection molding machine, there are three kinds of plunger type, screw type and screw type. Currently the most widely used is the screw type. Its role is that in a cycle of plastic injection molding machine, a certain amount of plastic can be heated and plasticized in a specified time, and the molten plastic is injected into the mold cavity through a screw under a certain pressure and speed. After injection, the melt injected into the cavity remains stylized.

The composition of the injection system: The injection system consists of a plasticizing device and a power transmission device.

Screw plastic injection molding machine mainly by feeding device, barrel, screw, plastic components, nozzle part of the composition. The power transmission device includes an injection cylinder, an injection cylinder moving cylinder, and a screw drive (a melt motor).
