Product Description

PVC Pipe Extrusion Machine Production Line


Nowadays the PVC pipes are widely used. Compared with conventional metal pipe, are as followed.

  • Corrosion Resistant

  • With self-extinguishing and flame retardant;

  • Excellent in anti-aging character

  • The weight of PVC pipe is light, easy to flaring, bonding, bending, welding.

  • Installation workload and Processing cost are lower than metal pipe

  • Good electrical properties of resistance

  • Recycled and Environment-friendly.


In order to meet the customized production plan, various design concepts for equipment will be adopted.

Basically feeding system, conical twin-screw extruder, mould, vacuum calibration tank, cooling tank, haul-off machine, cutter, socket forming machine (optional) and stacker build up the complete production line.

If you want a customized production plan, please contact us to get more detailed information.

For a stable production with high performance we have a mature solution package, which involves design concept, manufacturing and assembly process. It can eliminates many potential risks during production.

The Core components such as motor and frequency inverter are chosen from the world famous brand, which guarantees a precise and reliable production.


Conical twin screw extruder

PVC compounds are sensitive to shearing and high temperatures. Therefore, we should gently process on either parallel or conical twin screw extruders, depending on the throughput requirements and pipe dimensions. As the professional equipment, the Conical twin screw extruder can process not only PVC compounds, the mixture of PVC and wood/composite but also compounds of PP/PE and wood powder.


The pipe form is shaped by mould with various raw materials. The special designing of our mould provides ideal viscosity of material melting, which influences the pipe shaping and extrusion energy. All faces in contact with material are polished, for that reason, the extrusion friction can be minimized.

Pipe Extrusion Process Langbo Machinery

Vaccum Calibration Tank & Cooling Tank

Through the Vacuum Calibration Tank, the pipe shape will be defined. Besides that the surface quality of pipes is influenced by this step. LANGBO Vacuum Calibration Tanks are manufactured with stainless steel. The spraying nozzles are designed for maximum cooling performance. The Cooling water sprinkles on the hot plastic pipe surface. Combined with the shaping of the mould, the surface quality of pipes will be defined.

The pressure on our vacuum tank can be adjusted, so vacuum pressure can be fixed according to the pipe requirements. We seal gasket for every lid on the vacuum tank. This stops vacuum leakage and minimizes energy consumption. We adopted the sophisticated process technology in order to guarantee the quality of our products.

Haul off Unit

We have a wide range of haul-off units which can provide customers for the ideal solution with the diameter range of 16 to 800 mm.

Caterpillar and Belt Haul-off units can be adopted in accordance with the production conditions.
Haul-off speed can be connected with the extrusion speed, so that the wall thickness are more symmetrical.

The Belt Haul-off unit is usually used for small pipe and high speed extrusion. It is free from vibration and ensure the excellent control even at high speed. The Caterpillar can take the big pipes easily. The Claws' surface is covering with foam PU which can prevent the slip between pipes and claws. The speed setting of belts and caterpillar can be adjusted by inverter. Therefore, man can operate on the control panel easily.


A cutter with high performance can ensure the same length of the cut pipes. So the high quality encoder and precise cutter unit are needed. Similar like Haul off unit, the cutter has two design concepts: saw cutter and planet saw cutter. It depends on the diameter of cutting pipes.

Control system

The Control system includes the whole operations related controller and executor such as PLC module, HMI panel (Human Machine Interface), thermometer, connector and so on. The Elements with high quality is significant for a stable and precise production.


Optional unit

For pipe production, there are some functional units like laser, ink printer, pipe stacker and socket forming machine.

With Printer the Pipe Manufacturer can write the production information on the Pipes.

Stacker can be used to collect the pipes after cutting.

Socket forming machine can form one end of the pipe into a bigger diameter, so that the two pipes can connect end to end.


Production Capacity has a close relationship with screw size and motor power. The following table provide you a roughly classification of our pipe production solution.
