The single-screw exhaust extruder consists of an Archimedean screw rotating in a heated barrel. Because of its simple structure, easy manufacturing, high processing efficiency, low price and is widely used, is the most mature technology, the largest amount of extruder type. Single screw extruder has been developed from the initial basic spiral structure, such as damping screw block, exhaust screw, slotted screw barrel, pin barrel, building block structure and other different structure types, at the same time, because of the small space occupied by single screw extruder, has become the main equipment used in the field of composite processing and plastic blow molding film. Extrusion system mainly includes feeding device, screw and barrel parts, it is the most critical part of the extruder, wherein the screw is the heart of the extruder, the material through the rotation of the screw can move in the barrel, and get pressurization and part of the heat.
Our company specializes in the production of single screw exhaust screw barrel using high quality alloy steel 38CrMoAIA, nitriding treatment, surface alloy treatment, higher hardness. New screw structure, melting and mixing evenly, to ensure low melting temperature, high yield. With advanced design, high quality, good plasticizing, low energy consumption, stable operation, large bearing capacity, long life and so on.
Scope of application:
Mainly used for extruding soft, hard polyvinyl chloride, polyethylene and other thermoplastic plastics, can process a variety of plastic products, such as blowing film, extrusion pipe, pressure plate, wire drawing belt, can also be used for melting granulation.
