The single screw extruder consists of an Archimedean screw rotated in a heated barrel. Because of its simple structure, easy manufacturing, high processing efficiency, cheap price and widely used, it is the most mature technology and the most used extruder type.
Single screw extruder has developed from the initial basic spiral structure, such as damping screw, exhaust screw, slotted screw, pin barrel, building block structure and other different structural types, at the same time, due to the small space occupied by the single screw extruder, it has become the main equipment used in the field of composite processing and plastic blow molding film.
