How To Reduce Wear Of The Screws And Barrels? (二) Jul 23, 2018

The speed should be adjusted properly. Because some plastics have added reinforcing agents such as fiberglass, minerals or other fillers. These materials are typically much more abrasive on metallic materials than molten plastics. When these plastics are injected, if the rotational speed is high, the shear force on the plastic will increase, and the reinforcement will correspondingly produce more broken fibers. The shredded fibers contain sharp ends which greatly increase the wear force. When the inorganic mineral slides on the metal surface at a high speed, the scraping effect is not small. Therefore, the speed cannot be adjusted too high.

Any problems of plastic extrusion screw, can contact us.
