Plastic pipe extrusion lines can use almost the same method as blown film extrusion die heads to manufacture pipes such as PVC pipes.

 

The appropriate pressure may be applied to the internal cavity on the entire snare, or unnecessary pressure may be applied to the surface diameter by a vacuum separator to ensure proper closure measurement.

 

Adding appropriate internal mandrels in the parish may increase the lumens or holes.

 

Multi-layer electrical appliances may also be included in the automotive industry, plumbing, heating business and packaging markets.

Main material

The resins widely used in pipe production are plastic materials, such as PE and PVC.

 

For your plastic pipe extrusion line, material guarantees may be required. For example, many pipe manufacturers use PVC.

 

The resin is not only sensitive to heat, but also has a high viscosity under conventional processing requirements, so it cannot be processed. It requires compounding.

 

PVC compounding is a process of mixing additives with base resin to find a homogeneous mixture.

 

The included additives have improved processing skills or enhanced product handling properties.

 

Elements of pipe extruder process

·Extrusion Line

·Pairing Apparatus

·Die

·Cooling System

·Pulling and Cutting Tools

 

First, plasticizers are used to make the resin thicker and lower the viscosity, thus making the PVC preparation process easier.

 

It is expected that thermal stabilizers can prevent thermal degradation at process temperatures. Degradation involves the development of HCl and repair discoloration. Now the commonly used stabilizers can be determined.

 

The purpose of lubricants is to reduce friction during processing, which may lead to degradation. There are two types of lubricants used, namely internal lubricants and external lubricants. Reduce costs and improve the mechanical parts of all commodities including fillers and reinforcements. Both can improve rigidity, hardness, thickness and flame retardancy.

Pipe extrusion die head:

The function of the extrusion die is always to produce the necessary cross-section of the molten material supplied by the thread.

 

Cooling system:

During the entire sizing process, the pipes will also become cold. Cool by spraying water on the top of the tube. Compared with PVC, the amount of cooling in the entire PE is much more.

 

Elimination machine:

The drawing machine ensures uniform pipe size. Pullers are the caterpillar type of this balance wheel type. Electromagnetic or electronic speed changes are controlling the puller speed.

 

Control system:

They provide automatic measurement and control of pipe size. In one method, the capacitance of the pipe is quantified. It is close to depth. The sensing tip is wrapped around the tube, and once the tube is out of range, it will be exposed, so it is usually overweight or underweight.

 

Cutting equipment:

The special cutter can reduce the vinyl to the span. And automatic cutting equipment has not been fully utilized. At the same time, they cut the pick-up time and another pipe period and cut them with pipe lines.
