Counter-Rotating Parallel Twin Screw Extruder



SJP Series Counter-rotating Parallel Twin Screw Extruder
  • Applicable Products: Pipe, Profile, Pellets, Sheet, Plate and Board, etc.
  • Applicable Material: PVC powder
  • Alias: Twin screw extruder, parallel twin screw extruder, double screw extruder,counter-rotating twin screw extruder,compounding extruder, compounding extrusion machine, anisotropy parallel twin-screw extruder

The SJP series counter-rotating parallel twin-screw extruders are specially designed  for PVC powder extrusion, especially suitable for high-speed profile extrusion, and extrusion of large diameter pipe. Adopts with different mould and auxiliary devices, it could be used for producing PVC pipe, profile, sheet, plate, board and pellet, etc. The screw was designed with oil cooling system. To get best plasticization and material quality, Audop will equip the corresponding structure screw based on customer's formula.

To ensure that each similar extrusion equipment with the same high degree performance, the screw of counter-rotating parallel twin-screw extruders are all produced by the special high-precision CNC screw milling machine. Take the lead in the introduction of the most advanced screw design techniques of variable pitch and variable depth. Materials in the screw shear, compression more gentle, closer to the actual needs. Special design of dispenser box, with bigger thrust bearing, imported bearings, long life transmission, work under more extrusion pressure. Most of the electric components adopt import parts, with failure alarming function.

Counter-rotating Parallel Twin Screw Extruders are used for:

  1. PVC pipe extrusion
    Counter-rotating twin screw extruders are suitable for extrusions of PVC pipe, especially suitable for extrusion of large diameter pipe..
  2. PVC profile extrusion
    Counter-rotating twin screw extruders are widely used for making kinds of profile, especially suitable for extrusion of high-speed profile extrusion.

Audop supplies all the counter-rotating parallel twin screw extruders and corresponding auxiliary machines or systems to meet your business demands. You get the freedom to build your extrusion line around the system components that meet your exact requirements. All subsystem and support equipment such as feeding device, dies, control panels, etc may be included to provide a total system concept. The end result is superior quality, highly reliable machines that turn products into bigger profits for you.

While the above may sound similar to other suppliers, we can assure you that the specific execution that we utilize is dramatically better. Upon request we can provide further specifics of our unique and proprietary approaches, on-going continuous improvements.
