High output factory supply PVC four pipes making machine manufacture

Φ16-32mm PVC pipe extrusion line

This line can be used in the area of cable pavement pipes production. Whole line consists of conical twin screw extruder, four cavity mould, vacuum calibration cooling tank, haul-off, cutter, tripping table /belling machine,etc. And the line can be equipped with PLC control, ink-jet/laser printer, crusher, shredder, Pulverizer ,water chiller, air compressor etc.  Advanced design for screws and barrel supplies powerful safeguard for the PVC plasticization.
