Extrusion molding is plastic forming the important method of forming process, and extrusion molding in extrusion machine is the extruder, so is the plastic molding processing machinery major equipment. Extruder production with the products widely used in people life and agriculture, construction, petroleum chemical industry, machinery manufacturing, defense industries as well. Extruder is not higher than the polymerization with raw materials and add the owner needed assistance raw material mixing, mixing rubber plasticizing melting, eventually processed into has all kinds of cross-section shape and geometry size of plastic extrusion products. Its main characteristic is: production continuous; High production efficiency; Application range; Small investment, fast convergence. Extrusion machine mainly by extrusion system, charging system and transmission system and heating, cooling systems. This design is a few parts around this design. Extrusion system mainly by the screw and barrel composition, is a key part of the extruder. Processing of plastic is the high polymer. Comprehensive all aspects of the factors, screw structure of the selected for isometric darker type screw. Machine tube
