[0002] The extrusion molding unit for co-mixing and plastic product processing is a key piece of equipment used in plastics processing. It is primarily used to mix and extrude plastic raw materials of varying composition into the desired product. After the material enters the barrel through the feed port, it is gradually compacted and conveyed forward by the screw. The rotating screw generates shear forces that break, orient, and reorganize the material's molecular chains, while also promoting mixing and dispersion. The barrel's heating system heats the material according to process requirements, molten plastic, and provides the necessary activation energy for chemical reactions. Finally, the material is extruded through the die head to form the desired plastic product or semi-finished product.
