Vertical injection molding machine is an important plastic processing equipment. With the large demand for plastic products in recent years, many plastic products companies pay more attention to the processing quality of injection molding machines. Therefore, when using the injection molding machine, you should know more about the function, nature, processing method, and injection molding machine of the vertical injection molding machine. You should understand the operation of each system of the vertical injection molding machine, and it should be well maintained. The screw is an important part of the vertical injection molding machine and plays a key role in the injection molding process.

Vertical injection molding machine screws work under long-term high temperature, high pressure, high mechanical torque and high friction environment, so they must have strong performance to meet the needs. Many vertical injection molding machine screws are specially treated, such as nitriding, which enhances the hardness of the screw surface or improves wear resistance. In the injection molding process, the injection molding machine is required to reduce the wear of the screw by the injection molding machine. Otherwise it will be easier to reduce the working life of the vertical injection molding machine screw.
