Extrusion Molding, mainly refers to the extrusion of a screw or plunger to force the polymer material melted by heat to pass through the die of the die under pressure. Forming into a continuous profile with a constant cross-section. The extrusion molding process mainly includes the processes of feeding, melting and plasticizing, extrusion molding, shaping and cooling.
The extrusion molding method can produce continuous products of various forms such as pipes, bars, sheets, profiles, wire and cable sheaths, monofilaments, etc. It can also be used for mixing, plasticizing, granulating, coloring and polymer Blending modification of materials, etc.
