equipment of plastic forming and blending modification. In the actual blending modification production process, the screws of the extruder are exposed to harsh high pressure and high temperature environment, and are subjected to huge friction and shear forces. Due to the special working environment, the extruder screw is not a common metal-to-metal friction, but a metal-polymer, so the wear of the screw surface is often serious. The wear of the screw increases the spacing between it and the barrel, which affects the compression and shearing of the material by the screw, which will lead to a decrease in product quality.
