Barrel working principle

- Jul 03, 2018 -

In the plasticization process of plastics, the power of advancement and mixing is derived from the relative rotation of the screw and the barrel. According to the different forms of plastic in the screw groove, the screw is generally divided into three sections: a solid conveying section (also called a feeding section), a melting section (also called a compression section), and a homogenization section (also called a metering section).


Renovation barrel process

The inner surface of the barrel is harder than the screw and it is damaged later than the screw. The scrapping of the cartridge is such that the diameter of the inner diameter increases due to time wear. Its repair method is as follows:


1. The barrel with increased diameter due to wear. If there is a certain layer of nitrided, the inner hole of the barrel can be directly bored, ground to a new diameter, and then the new screw is prepared according to the diameter.
