5. Human-computer interface is easy to operate, convenient and reliable.
6. Spiral and lattice basket type die dead for choice.
7. Changing some parts of the line can also realize two-layer and multi-layer co-extrusion.
8. Changing some parts of the line can also produce PP, PB pipes.

Technical Data

Single Screw Extruder

Simens Touch Screen and PLC
Apply program developed by our company, have English or other languages to be input into the system.

Spiral Structure of Barrel
Feeding part of barrel use spiral structure, to ensure material feed in stable and also increase feeding capacity.

Special Design of Screw
Screw is designed with special structure, to ensure good plasticization and mixing. Unmelted material can not pass this part of screw.

Air Cooled Ceramic Heater
Ceramic heater ensure long working life. This design is to increase the area which heater contact with air. To have better air cooling effect.

High Quality Gearbox
Gear accuracy to be ensured 5-6 grade and lower noise below 75dB. Compact structure but with high torque.

Extrusion Die Head

Extrusion die head apply spiral structure, each material flow channel is placed evenly. Each channel is after heat treatment and mirror polishing to ensure material flow smoothly. Die head structure is compact and also provide stable pressure, always from 19 to 20Mpa. Under this pressure, pipe quality is good and very little effect on the output capacity. Can produce single layer or multi-layer pipe.

Moving Device of Die Head
For big size die head, moving device can move die head forward and back, also adjust the height of die head. Operation is fast and easy.

Die Head Rotary Device
For big size die head with rotary device, die head can rotate by 90 degree. When changing bush, mandrel, die head will turn 90 degree. Can use crane to lift and change bush and mandrel. This way is very convenient.

Heat Exhausting Device
This device is added on die head to produce big and thick pipe. To exhaust heat inside the pipe and cooling pipe inside wall. The heated exhausted can be used to dry the raw material.

Cooling Device for Core
When produce pipe with big diameter and wall thickness, we will use cooling water or oil together with cooling fan to cool the core of die head to avoid over heating and ensure good material quality.

Vacuum Tank

Strong Cooling for Calibrator
With special cooling system for calibrator, which can have better cooling effect for pipe and ensure high speed. Also with good quality spray nozzle to have better cooling effect and not easy blocked by impurities.

Better Support for Pipe
For big size pipe, each size have its own semicircular support plate. This structure can keep pipe roundness very well.

Silencer
We place silencer on the vacuum adjust valve to minimize noise when air come into the vacuum tank.

Pressure Relief Valve
To protect the vacuum tank. When vacuum degree reach maximum limitation, the valve will open automatically to decrease vacuum degree to avoid broken of tank. Vacuum degree limitation can be adjusted.

Double Loop Pipeline
Each loop with water filtering system, to provide clean cooling water inside tank. Double loop also ensure continuous providing of cooling water inside tank.

Water, Gas Separator
To separate the gas water water. Gas exhausted from upside. Water flow into the downside.

Full Automatic Water Control
With mechanical temperature control to have accurate and stable control of water temperature.
Whole water inlet and outlet system is controlled full automatic, stable and reliable.

Centralized Drainage Device
All water drainage from vacuum tank are integrated and connected into one stainless pipeline. Only connect the integrated pipeline to outside drainage, to make operation easier and faster.

Cooling Tank

Pipe Clamping Device
This device can adjust pipe roundness when pipe comes out from the vacuum tank.

Water Tank Filter
With filter in the water tank, to avoid any big impurities when outside water comes in.

Quality Spray Nozzle
Quality spray nozzles have better cooling effect and not easy blocked by impurities.

Pipe Support Adjusting Device
Support with adjustment function to support pipe with different diameters.

Pipe Support Device
Especially used when producing pipe with big diameter and wall thickness. This device will provide additional support to heavy pipes.

Haul Off Unit

Separate Traction Motor
Each claw has its own traction motor, in case when one traction motor stop working, other motors can still working. Can choose servo motor to have bigger traction force, more stable traction speed and wider range of traction speed.

Claw Adjustment Device
All claws are connected to each other, when adjusting position of claws to pull pipe in different sizes, all claws will move together. This will make operation faster and easier.

User Friendly Design
With Siemens hard ware and user friendly software designed by our company. Have synchronized function with extruder, make operation easier and faster. Also customer can choose only some of claws to work to pull much smaller pipes.

Separate Air Pressure Control
Each claw with it own air pressure control, more accurate, operation is easier.

Cutter

Universal Clamping Device
Apply universal clamping device for different pipe sizes, no need to change clamping device when pipe size changes.

Saw and Blade Interchangeable
Some cutters are equipped with both saw and blade. Saw and blade cutting are interchangeable for different pipe sizes. Also, saw and blade can work together for special requirement.

Central Height Adjustment
With electrical adjusting device for clamping device. Operation faster and easier. With limit switch to ensure safety.

Stacker

Pipe surface protection
With roller, to protect pipe surface when moving pipe.

Central Height Adjustment
With simple adjustment device to adjust the central height for different pipe sizes.

Coiler

To coil pipe into roller, easy for storage and transportation. Usually used for pipe below size 160mm. Have single station and double station for choice.

Use of servo motor
Can choose servo motor for pipe displacement and winding, more accurate and better pipe displacement.
