CAD ????θ QQ 194535455 Abstract Extruder, the host is crowded molding machine, it posed of extrusion system, transmission system and heating cooling system. Extruder is a kind mon plastic machinery and equipment, in recent years, China's conventional extrusion machine and production line, with excellent cost-effective popular international market gradually. At the same time, China in the field of advanced extrusion technology innovation, develop a variety of new e out. Extrusion technology to meet the need of high precision processing Precision extrusion can be removed from the follow-up processing method, better meet the needs of product application, at the same time to reduce the cost of materials, the purpose of improving the quality of the products. Today, meet the needs of plastic precision direct extrusion, a variety of mature technology has been to the market, the polymer melt gear pump is one of the important means. This technology has been widely used in chemical fiber, film, profile, pipes, plates, wire, composite extrusion, such as granulation production lines. Single screw plastic extruder using a single reducer, normal profile is used for a single screw barrel, screw, high quality carbon steel. Special request is made of high strength and corrosion resistance of с?????
