Why wear occurs, Watanabe Manufacturing will explain in detail.
Watanabe Manufacturing, a leading company that provides comprehensive support from the design and manufacturing of injection molding machines, extruders, screws, cylinders, and molds to subsequent maintenance, explains the "causes of wear." There are many reasons why screws and cylinders wear out. They can be broadly classified into three categories: "abrasive wear," "corrosive wear," and "adhesive wear." 【Features】 ■ Abrasive Wear - A phenomenon where hard particles come into contact with the outer circumference of the screw and the inner surface of the cylinder, causing material to be scraped off. ■ Corrosive Wear - Occurs due to corrosive chemical components generated during the heating and melting process of the resin, which chemically attack the outer circumference of the screw and the inner surface of the cylinder. ■ Adhesive Wear - Occurs due to metal contact between the surfaces of the screw and cylinder caused by resin retention. *For more details, please refer to the PDF document or feel free to contact us.
