The screw barrel is one of the necessary components of plastic processing machinery. It is the ultimate requirement of plastic processing machinery, and the production process cannot be completed without the use of a screw barrel. This tool ensures that the product is smooth and the output reaches the expected speed.
The material of the screw and barrel is strong in structure, high in strength, and low in maintenance. But it is very durable and is generally used in other industries, such as food processing machinery, cable machinery and other small-scale industries. By definition, its main purpose is to smooth the production process and obtain the required output. The screw is an important part, and its function is to transport, melt, compact, stir and press the plastic. All of these are accomplished by the rotation of the screw in the barrel, which shows that the role of the screw is decisive.
The barrel has been working under high pressure, high temperature, high mechanical torque and high friction environment for a long time, and the loss caused by friction is inevitable. Generally, the screw has undergone surface nitriding treatment to increase the surface hardness, that is, to improve the wear resistance. However, if the cause of wear is ignored and the wear is not minimized, the service life of the screw will inevitably be greatly reduced.
