What is Plastic Extrusion?

The plastic extrusion process does exactly what it says on the tin – extruding plastic to create both standard and bespoke profiles. In fact, we can outline the steps as simply as follows: 

  1. Granular plastic is held in a hopper 
  2. It is moved through the heating chamber 
  3. Once the polymer has been melted, it is pushed through a die, which will form the shape of the extrusion as required by the specifications

The plastic extrusion process takes granular pieces of plastic through various components of the extruder to end up in a continuous profile with the help of heat and pressure. 

Although plastic extrusion has a lot of elements and phases, it is quite a simple process that leads to the development of specific components. More pieces can be processed accurately and in a time-efficient manner thanks to plastic extrusion.

While the steps of the process itself sound quite simple, as you can imagine it is the machinery itself that undertakes most of the technical side of things. Plastic extrusion machines are complex, with systems in place to create the desired profiles down to the tiniest specified detail. These, along with the expert supervision of our extrusion team here at Rocal Extrusions, ensure you get the profiles you need.

Advantages of Plastic Extrusions 

Plastic extrusion is one of the most used and highly regarded processes in the plastic industry due to its many advantages. We could wax lyrical about the benefits of our products and machinery, but for now, we’ll outline a few of our team’s favourite positives. 

  • Minimal waste production – thermoplasics used in extrusion can handle multiple processes, so any would-be waste can simply be reshaped and reused
  • Complex cross-sections – the bespoke manufacturing process means your required specifications can be achieved through innovative, intelligent production
  • Continuous operation capabilities – thanks to ongoing processes, we’re able to pass on to our customers lower costs and faster turnaround times 
  • Versatility of materials – extrusion processes can work with many types of raw materials, including both flexible and rigid plastics as the job requires 
  • High-quality surface finish – exceptional results to give the aesthetics you need, as well as the performance beneath the surface that you can rely on 
  • Customisability – bespoke options available to suit your spec, such as fire resistance, improved durability and environmental sustainability 

The advantages of plastic extrusions are many, as are the advantages of working with an experienced, reliable company such as Rocal Extrusions. With many years of experience under our belts and many more ahead, you can enjoy all these benefits and more for your next project.
