Plastic Extrusion

Plastic Extrusion

The Plastic Extrusion process is at the core of Tech Plas, it is what we live and breathe. We specialise in custom plastic extrusions and pvc plastic extrusions, making plastic profiles for all uses and industries.

Plastic Extrusion is the process of applying heat and pressure to melt plastic polymers such as PVC, polyethylene and ABS to name a few. Once heated the polymer is forced through a die to produce continuous shapes of the profile or pipe. There are many shapes that can be produced by extrusion and the dimensions of these shapes are dictated by the size of the die which is the shaping tool that’s bolted onto the front of the extruder machine.

PVC Extrusion, Plastic Extrusion by Tech Plas Plastic Extrusions

Before the plastic extrusion process begins, the die is built by TECH PLAS’ highly trained toolmakers to dimensions that reflect the specifications of the shape that is to be produced. Manufactured shapes can take many forms, but TECH PLAS specializes in:

  • Profiles to suit every imaginable industry application.
  • Pipes (both commodity and specialist shapes and textures).
  • Custom designed products to suit special applications and customer’s individual needs.

Manufacturing the tooling and calibration required to produce extruded plastic profiles can often take up to 12 weeks depending on the size and complexity of the required profiles. With over 30 years of tool making experience Tech Plas can guarantee the highest quality and  most economical solution for your tooling requirements, whether we design and manufacture in-house or project manage the construction overseas.
