Main machines of PVC pipe extrusion line


Both conical twin screw extruder and parallel twin screw extruder can be applied to produce PVC pipe. With latest technology, to lower power and ensure capacity. According to different formula, we provide different screw design to ensure good plasticizing effect and high capacity.

Extrusion Die Head

Extrusion die head apply bracket structure, each material flow channel is placed evenly. Each channel is after heat treatment, mirror polishing and chroming to ensure material flow smoothly.
Die head is modular design, easy for changing pipe sizes, assembling, dismantle and maintenance. Can produce single layer or multi-layer pipe.

Vacuum Tank

Vacuum tank is used to shape and cool pipe, so as to reach standard pipe size. We use double-chamber structure. First chamber is in short length, to ensure very strong cooling and vacuum function. As calibrator is placed in the front of first chamber and pipe shape is formed mainly by calibrator, this design can ensure quick and better forming and cooling of pipe.

Haul Off Unit

Haul off unit provides sufficient traction force to pull pipe stably. According to different pipe sizes and thickness, our company will customize traction speed, number of claws, effective traction length. To ensure match pipe extrusion speed and forming speed, also avoid deformation of pipe during traction. 、


Cutter controlled by Siemens PLC with chamfering function, working together with haul off unit to have precise cutting. Customer can set the length of pipe they want to cut.

Belling Machine

To make socket at pipe end which is easy for pipe connection. There are three types of belling type: U type, R type and Square type. We provide belling machine which can finish belling of pipe on line fully automatic. From minimum size 16mm to maximum size 1000mm, can with multi heating oven and belling station.
