Roll forming is a solid working method in which the ultra-high molecular weight polyethylene (UHMW-PE) below the melting point exert high pressure, ultra high molecular weight polyethylene sales by particle deformation, ultra-high molecular weight polyethylene, effectively particle and particle fusion. The main device is a rotating wheel and a bow slider with a spiral groove with a tongue and groove of the tongue and groove with vertical grooves. History of the development of ultra high molecular weight polyethylene: the emergence of plasticized gel spinning method and spinning method of making UHMWPE major breakthrough in technology; the 1970s, the University of Leeds first developed a molecular weight of 100,000 high molecular weight polyethylene fibers.
