Causes of alloy screw wear of Zhoushan injection molding machine and methods of reducing wear
1. Each plastic has an ideal plasticizing processing temperature range, and the barrel processing temperature should be controlled to bring it closer to this temperature range. When granular plastic enters the barrel from the hopper, it will first reach the feeding section. Dry friction will inevitably occur in the feeding section. When these plastics are insufficiently heated and unevenly melted, it is easy to cause increased wear on the inner wall of the barrel and the surface of the screw. Similarly, in the compression section and the homogenization section, if the molten state of the plastic is disordered and uneven, the wear will also increase.
2. Speed should be adjusted properly. Because some plastics are added with reinforcing agents, such as fiberglass, minerals or other fillers. The friction of these materials on metallic materials is often much greater than that of molten plastic. In the injection molding of these plastics, if it is made with a high speed, it will not only increase the shear force on the plastic, but also cause the reinforcement to generate more shredded fibers. The shredded fibers contain sharp ends, which will cause abrasion. The force is greatly increased. When inorganic minerals glide on the metal surface at high speed, its scraping effect is not small. Therefore, the speed should not be adjusted too high.
