Twin Screw Extruder


Co-rotating Parallel Twin Screw Extruder consists of motor drive, torque distribution gearbox, processing section, temperature controlling units, direction and down-stream pelletizing system, etc.
Twin Screw Extruder adopts modular design principle, component standardization manufacturing, which can present stable and reliable performance.
Thanks to the modular principle, extruder scan provide highly customizable solutions according to customers’ process and special requirements. Based on different output torque grade, extruders have basic type and efficiency type.
Multiple cutting system can be combined with  Twin Screw Extruder, such as strands pelletizing, hot-face cutting and under-water pelletizing, etc.
Both Relay control and PLC control are available to apply in the electrical controlling system. All the key electrical parts adopt European brands to guarantee the controlling system with significant and stable performance.

Typical Applications:
Engineering plastics、Masterbatch、Filling、TPE/TPR/TRV、Direct extrusion
