The HDPE plastic pipe extruder is a high-efficiency and energy-saving machine designed for producing HDPE protective jacket pipes used in polyurethane (PU) foam pre-insulated pipelines.

It features a compact structure, easy operation, automatic control system, stable performance, and long service life.

Production line composition:
-1 set Vacuum loader 
-1 set Hopper dryer
-1 set High-efficiency single screw extruder
-1 set Vacuum calibration table 
-1 set Water spraying tank 
-1 set   Hauling machine
-1 set Cutting machine
-1 set   Stacker

---Pipe Usage: the outer casing of thermal insulating pipe, which is widely used in central heating, oil, natural gas and other industrial areas.
---Pipe/jacket diameter range: 110-1680mm
 

---High-efficiency extruder gives larger output, and stable performance.
---Pipe wall is average and smooth, to reduce waste of raw material, and pipe thickness is adjustable.
---No need to trim edge, once forming.
---High degree of automation, can be operated by one person, saving labor costs.

1. High-efficiency single screw extruder

---Single screw is with barrier & mixing head; new model barrel with slotting (channel), Both make the security of good jellification, large output and stable performance.

2. Die-Head
Die-head is mainly composed of mandril, neck mold, spiral body, cover, die-head body, bolts, and heating rings.
The inside surface touching with plastic materials is polished and chrome plated to ensure plastic materials flow smoothly and to ensure no rusting. The uniformity of pipe wall thickness can be adjusted by bolts. The copper calibrating sleeve fixed in die-head is mainly used to cool down the fresh pipe and to calibrate the pipe outer diameter.
3. Vacuum Calibration Tank
The vacuum calibration tank is mainly composed of frame, stainless steel tank, vacuum system, spray cooling system, position adjustment device. The vacuum pump exhausts the air from the sealed tank to pressurize the fresh pipe cling to calibrate the copper sleeve and to calibrate the outer diameter.  Spray nozzles spray cooling water from all directions on the pipe surface to cool down the pipe promptly.4. Haul-off Machine
Haul-off machine is mainly composed of driving device, tracks, clamping structure, adjusting system, side plate and foundation bed. Haul-off caterpillars are driven by AC motor with frequency conversion control to adapt to different extrusion speeds.
An automatic length measuring device realizes cutting at a set length.5.  No-Dust Cutter
It adopts the blade punching principle to realize no-dust cutting. It is mainly composed of a cutting device, clamping device, structure synchronous movement device and frame.6.Control system
The complete line could be controlled by PLC, with good human-machine interface, all technical parameters could be set and indicated by touching screen. Controlling system can be designed according to customers' requirements.
