Take advantage of twin-screw extruder and single screw extruder. Twin-screw extruder realizes transportation, high effective plasticizing and compounding, dispersion. Two stage machine can also increase the variable operation and realize the process. Higher effective and production capacity. Good at process heat-sensitive material and devolatilization operation.  JIEYA can provide two stage (twin screw+single screw) extruders for rigid/soft PVC cable compounding with over 20 years experience.
