SJ Series Single Screw Extruder

Single-screw extruder consist of an screw rotating in a heated barrel. Because of its simple structure, easy making, high processing efficiency and low price, it is widely used. It is the type of extruder with the most mature technology and the most consumption.


The single screw extruder is mainly composed of three parts: extrusion system, transmission system and heating and cooling system.


Pipe extrusion: suitable for PP-R pipes, PE gas pipes, PEX cross-linked pipes, aluminum-plastic composite pipes, ABS pipes, HDPE silicon core pipes and other co-extruded composite pipes.


Sheet/board extrusion: suitable for extrusion of PVC, PET, PS, PP, PC and other profiles and sheets.


Extrusion of profiles: adjusting the speed of the extruder and changing the structure of the extrusion screw can be applied to the production of various plastic profiles such as PVC and polyolefins.
