Introduction 

Twice The Throughput With Double-Strand Extrusion

Double strand extrusion doubles the extruder’s throughput of small-diameter pipe.
Adjusting the haul-off speed and the cutter function separately for each strand cuts material consumption to an all-time low,

because differences in material flow can be allowed for and wall-thickness kept within tight tolerances.shapes.

SJZ80/156 twin screw extruder 

Conical twin screw extruder or 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.

Double Extrusion die head apply bracket structure, each material flow channel is placed evenly. 

Each channel 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. 

Vacuum calibration tank is used to shape and cool pipe, so as to reach standard pipe size.

We use double-chamberstructure.First chamber 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 coolingof pipe.

2 Caterpillar 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 matchpipe extrusion speed and forming speed, also avoid deformation of pipe during traction.

Dust free Cutter controlled by Siemens PLC, working together with haul off unit to have precise cutting. Customer

can set the length of pipe they want to cut.Multi-feed-in actions for the accomplishment of one cutting process

(protect blades and saws, prevent from blade and saws stuck for thick pipe and cut face of pipe is smooth).

PVC on-line 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 min size 16mm to max size 800mm, can with multi heating oven and belling station.
