POLESTAR Machinery is a specialized manufacturer of advanced extrusion machinery for PE/PP pipe production. We are a trusted provider of integrated Plastic Pipe Extrusion Machine solutions, designed for efficiency and reliability.
Our flagship product line includes the robust SJ Series single screw extruders. These are complete, high-performance systems engineered for continuous operation. For instance, our SJ35 model is capable of producing pipes with diameters ranging from 16mm to 50mm. It features a maximum haul-off speed of 15m/min, a main motor power of 18.5-30Kw, and achieves a maximum extrusion output of 90Kg/hour. This model can also function as a standalone Plastic Pipe Extrusion Machine, backed by our comprehensive technical support.
Our expertise extends across both single and twin-screw extruder technologies. The single-screw extruder operates by continuously conveying, melting, compressing, and extruding solid polymer within a heated barrel. Its compact footprint and operational efficiency have made it a cornerstone machine in various fields, including composite material processing and plastic profile manufacturing.
Beyond core extruders, our integrated workshop also manufactures critical auxiliary equipment, such as PE/PP granulators, plastic pipe haul-off units, and precision cutting machines. This allows us to provide a true one-stop service, helping you configure the optimal combination of machines to maximize your production line's efficiency. All equipment is supported by our unified, professional after-sales service.
