Plastic extrusion die

Used to shape the production of continuous shapes of plastic products, a class of molds, also known as extrusion molding head, widely used in pipe, bar, monofilament, sheet, film, wire and cable cladding, profiles and other processing. The corresponding production equipment is a plastic extruder, the principle is that the solid-state plastic in the heating and extruder screw rotation pressure melting, plasticizing, through the specific shape of the mouth mold and made of the same cross-sectional and die shape of the same continuous plastic products. Its manufacturing materials are mainly carbon structural steel, alloy tools, and some extrusion die in need of wear-resistant parts will be inlaid with diamond and other wear-resistant materials. The extrusion process is usually only applicable to the production of thermoplastic products, which is structurally different from the injection mold and plastic mold.
