UHMWPE molding: special. The production of ultra high molecular weight polyethylene (UHMW-PE) sheet, polyethylene chopping board production plant by a metering pump into the cavity delivery SH200 silicone oil as a lubricant, the resulting appearance of the product quality has significantly improved, especially since the extrusion small deformation polyethylene cutting board price increase of tensile strength. Roll forming is a solid working method in which the ultra-high molecular weight polyethylene (UHMW-PE) below the melting point of its high voltage is applied, polyethylene chopping board, by particle deformation, effectively particles 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.
