Shanghai Jinwei Chemical Fiber Extruder Screw

Description :

　　The JWM series screw extruder is mainly used for melt spinning of PET, PA6, PA66, PP and other chips. This product combines over a decade of experience and technology, with huge annual sales in the industry. Currently, thousands of extruders are operating normally in over 700 chemical fiber and non-woven fabric factories. The screw design of the extruder adopts LTM low-temperature mixing elements, which have good plasticizing performance. Due to the use of processing technology, the manufacturing accuracy and linearity of screws and barrels are high. And a high-precision helical gear reducer is selected, with hard tooth surface grinding gears. Work smoothly, with low noise. Equipped with super strong thrust bearings to ensure the ability to withstand enormous axial forces. Imported bearings and seals can be selected according to user needs, with good durability and easy maintenance.
