[0002] Extrusion molding, also known as extrusion molding in plastics processing, is a process in which the material is forced through the die itself using hydraulic pressure in non-rubber extruders. This process involves the material passing through the extruder barrel and screw, plasticized by heat while being pushed forward by the screw, and continuously passing through the die head to form finished or semi-finished products of various cross-sections. Pipe production is one such process. Currently, large-diameter plastic pipes are primarily extruded through the extrusion cavity between the die core and the die sleeve.
