Comparison of wear-resistant and corrosion-resistant ability High Wear Resistant Screw The Japan Steel Works, Ltd. Plastics Machinery Business Division Fig. 1 and Fig. 2 show comparison of wear resistance and corrosion resistance among the new developed LSP-M and the existing screws of JSW. For example, in a production extruder for ceramic In recent years, increasingly high wear and corrosive resistance has been required for plastics processing extruders along with the development of high-perfor- compounding, metal particles from screw wear in products have been dramatically reduced to 1/20 with LSP-M screws. That was highly appreciated by the customer. mance plastics filled with high concentration of glass fiber, ceramics, ferrite, or the like. To meet demanding requests of users, JSW has developed “LSP-M” screw. It achieved high wear resistance approx. 20 times above the conventional JSW screw material LSP-2 in a certain production machine. Here, we introduce some advantages of “LSP-M”. Your Benefits "LSP-M" has excellent wear resistance while keeping high corrosion resistance comparable to LSP-2. This material is also available for strand dies. Sharp edge can be kept for longer time because of high wear resistance and it Fig.1 Abrasive Resistance Test helps reduce polymer sticking around die outlet. Now, we can supply "LSP-M" screws up to TEX105 size to meet customers’ demand. Japan Steel Works, Ltd.
