●PVC Double pipe (trunking pipe) extrusion line Combined with the western advanced technology development, the machine can producing two or four PVC pipe at the sametime. Using SJSZ-51/105 Conical twin screw extruder, double or pipe mould, double Vacuum Cooling calibration tankm, double haul-off Machine, double cutting Machine and double stacker.

●Special screw design. The materials in the barrel short residence time, Mixing, plasticizing effect.

●adopt the high quality reduction gear box, Beautiful appearance, smooth running, low noise, Adopt the vacuum exhaust system, The volatile gas and the water in the material discharge, improve quality of the product.

●A double or four tube, the production efficiency is more than doubled, alone control, practical, convenient operation.

The main motor adopts thyristor DC speed or frequency converter controling. The motor runing stability, the machine using PVC prowder material producing directly. Labor saving, high production efficiency, PVC trunking pipe on the outer diamemter of the pipe annotation, 16, 20, 32, 40 is the nominal standard diameter pipe. According to the pipe thickness, the internal diameter.

●First class pipe die was designed with many years experience.

●Perfect twin pipe vacuum sizing system.

●Controlled independently unitary structure twin pipe hauling mechanism and synchronous cutting device.

●Optional length set and accurate adaption stacker.
