PVC pipes are widely used in life and construction industry. We can see it everywhere, kitchen, bathroom, and so on.PVC pipes are anti-corrosion, water-proof and plasticity, people's life and production can not leave it. But how it manufactured?

how is PVC Pipes Manufactured by extrusion machine?

PVC pipes are manufactured by extrusion of raw material PVC, and generally follow the same steps of typical pipe extrusion operations:

  • Feeding of raw material pellets / powder into the PVC twin screw extruder

  • Melting and heating in multiple extruder zones

  • Extruding through a die to shape into a pipe

  • Cooling of the shaped pipe

  • Cutting of PVC pipes to the desired length

However, despite having a similar manufacturing procedure to most plastic piping, PVC pipes have intrinsic characteristics that pose additional challenges to pipe manufacturers both in terms of production, as well as positioning their products on the market.

The Challenges of PVC Pipe Manufacturing

Increased Extruder Friction

Due to the nature of PVC plastic, PVC extruders are subjected to high amounts of friction and stress. This means that to guarantee a long service life, PVC pipe production lines require the use of specialized extruders that utilize a twin screw extruder configuration, as well as featuring robust construction materials that can withstand the harsh PVC extruder operating conditions.

Differentiating From Competitors

Since PVC piping is one of the most used types of piping, there is a lot of competition between manufacturers. It is therefore of paramount importance for PVC pipe producers to differentiate themselves from their competitors, both in terms of delivering consistent product quality, as well as offering a wide range of products at competitive prices. Such differentiation can only be achieved through the use of world class manufacturing equipment, that maximizes productivity while minimizing costs and has the capacity to produce a wide variety of PVC pipe sizes. DRTS offers a range of effective turnkey solutions that guarantee this type of effective operation, such as equipment with integrated Industry 4.0 functionality, advanced connectivity, ease of integration and multi-layer die heads that maximize savings.
