                                      PVC twin screw extruder

Features:

    SJSZ series twin conical screws extruder is a kind of special equipment for extruding of PVC powder. With different sorts of molds and auxiliary machines, it can produce all sorts of PVC plastic pipe material, profiled material, plate material, sliced material, bar material and granulation. It can also extrude PP.PE pipe at high speed by changing special barrel.

   Computer control or conventional control is optional. According to customer's requirements, most reasonable screw can be made so as to achieve best plasticity state and material quality. The screw is made by high precision special digital screw miller, extruding property can be highly harmonized. It has firstly introduced advanced technique of producing screws with variable pitch and depth, so that the material can be more softly sheared and cut. The distribution box is specially designed, the drive life span can be prolonged. It can bear larger extruding pressure.
