What is the Process of PVC Pipe Extrusion Line?

PVC pipe extrusion line is a combination of diverse machines. All these machines work together to produce PVC pipes. There are diverse companies in the world that are producing PVC pipes. In the last couple of years, the manufacturers have introduced advanced PVC pipe making machines. These machines are efficient in every way due to which they increase the production speed. 

What is the process of PVC pipe extrusion line?

If you are going to set up a PVC pipe extrusion line, then you need to know the process of this line. When you will come to know the process, then you will be able to choose the best machines for it. The process of this extrusion line is explained as follows.

Feeder

The first step in the plastic tube extrusion process is the feeding process. The plastic in powder form moves from the hopper to the extruder. In this way, the production process of the PVC pipe starts. The feeder has to be dependable and efficient. It should measure the flow of the powder and also monitor the additives.

Extruder

The next process is the main extrusion process. Here, the extruder melts the powder form and turns it into the granules. The melting process is performed within the barrel. With the help of two screws, the quality of the molten plastic material remains high.

Die Head

Die head process is performed right after the extrusion process. This process is important to shape up the product. The molten form of PVC enters into the die with a constant flow. Now, the PVC molten material transforms into a PVC pipe. The constant flow of molten PVC is needed to perform this process. 

Cooling

When the PVC pipes are shaped up, then they are taken to the cooling machine. In the advanced PVC making machine, there is a cooling section. This section has a vacuum setting to keep the shapes of PVC pipes. The machine throws cooling elements onto the pipes to lower down their temperature. When the pipes become cold, then the machine sprays fresh water on them. In this way, the pipes become rigid, strong, and durable.

Scanner

The scanning process is used to check the quality of the PVC pipes. Many PVC pipe extrusion line suppliers are offering the scanners along with PVC pipe extrusion machines. The scanner scans the wall thickness of the pipes. If the thickness is consistent, then the pipe is good. Otherwise, it is considered as a low-quality pipe. 

Haul off

A haul off is also involved in the plastic tube extrusion process. The haul-off is used to pull off the pipe with a high speed through the extrusion line. The speed should constantly be fast to save the form of the pipes. 

Cutter

When all steps are performed, then the pipes are cut through the cutting equipment. The equipment trims down the pipes into a standard size. After that, they are ready for delivery.

Final Words

Now you know the process of the PVC pipe line. In the early decades, manufacturers need to use many machines to form these pipes. With time, the makers of the machines incorporated the latest technological innovation. Due to this reason, the latest PVC pipe machine can perform many steps. In this way, the pipe manufacturers do not have to buy a bunch of machines to set up the extrusion line.
