UHMWPE forming: General. Extrusion. China in the end of 1994 developed the ultra-high molecular weight polyethylene Φ45 single screw extruder, and made Φ65 single-screw extrusion production line pipe industrialization success in 1997. Injection molding. Of 1983 on the domestic XS-ZY-125A-type injection molding machine was modified Buying ultra high molecular polyethylene filter plate, successfully injected a beer canning line with ultra-high molecular weight polyethylene (UHMW-PE) roller, water pump shaft Plates sets of ultra high molecular weight polyethylene prices in 1985 and successfully injected a medical artificial joints. UHMWPE forming: heat treatment. With heat-treated ultra high molecular weight polyethylene (UHMW-PE) powder pressing the articles and not heat-treated UHMPWE products compared to the former have better physical properties and transparency, smoothness and low temperature mechanical properties of the product surface greatly improved.
