Introduction to Plastic Extrusion Dies

A type of mold used to shape and produce plastic products with continuous shapes, also known as extrusion molding heads, is widely used for the processing of pipes, bars, monofilaments, plates, thin films, wire and cable coatings, and profiles. The corresponding production equipment is a plastic extruder, which is based on the principle of melting and plasticizing solid plastic under heating and rotating pressure conditions of the extruder screw. Through a specific shape of the die, it is made into a continuous plastic product with the same cross-section and die shape. Its manufacturing materials mainly include carbon structural steel, alloy tools, etc. Some extrusion molds also embed wear-resistant materials such as diamonds on the parts that require wear resistance. The extrusion process is usually only applicable to the production of thermoplastic products, and it has significant differences in structure from injection molds and compression molds.
