QQ 194535455 Abstract Plastic extrusion machine called extruder (extruder), it is one of the main equipment in the manufacturing process of plastic, the extruder is molding production line of the host, its role is shearing plasticizing material and transportation, and provide the required pressure molding products. Extruder can be used for molding pipes, bars, plates, sheets, film, wire and cable, hollow products, profile, the replica of the. In addition, screw extrusion is also used extensively for the polymer granulation, dehydration, blending, enhancement, reactive extrusion, alloying, feeding and color masterbatch. Based on extrusion and blow molding process plete the molding process. The use of screw extrusion polymer dating back more than 100 years of history. This processing method plays a very important
