PVC Conduit Pipe Extruder Production Line

PVC Conduit Pipe Extruder Production Line

PRODUCTION PROCESS FLOW 

The first step of pipe production is the preparation of raw material. Customers can mix the PVC powder with other additives by themself. The mixture will be feeded into extruder. The material will be plasticized in the extruder and then be extruded into the mould. The material is shaped by mould and goes out with the pipe looking. The pipe extruded from the mould is hot and soft. The pipe with unstable shape will be calibrated and cooled by vacuum sleeve in the vacuum calibration tank. And then the pipe goes into the cooling tank for a further cooling. Haul off unit stands next to the cooling tank and take the pipe away from the extruder. According to the defined length, the pipe will be cut and then packed for transport.

COMPONENTS INTRODUCTION

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.

Mould

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.

Vaccum Calibration Tank & Cooling Tank

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.

Cutter

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.
