SJ Series Single Screw Extruder

As one of the most widely used machines in the plastics processing industry, the single screw extruder plays a critical role in manufacturing plastic pipes, sheets, profiles, pellets, and other extrusion products. Known for its simple structure, reliable operation, and cost-effective performance, the single screw extruder remains the preferred choice for many plastic manufacturers worldwide.

What Is a Single Screw Extruder?

A Single Screw Extruder is an extrusion machine that uses a rotating screw inside a heated barrel to melt, mix, and convey plastic materials continuously. The molten material is then forced through a die to create the desired shape or product.

Its simple design and efficient processing capabilities make it an essential piece of equipment in modern plastic manufacturing.
