Production technologies

PVC profile extrusion, rigid and flexible

We extrude plastic profiles and gaskets with a constant cross-section – from rigid and soft PVC, TPE, ABS and PP, including co-extrusion. A technology of RefPlast, a brand of the AiFO Group.

Why extrusion

One profile instead of several parts

Extrusion delivers any cross-section you need along the entire length of the part – from a simple strip to a profile with air chambers that eliminate thermal bridges.

In co-extrusion we combine two plastics in a single cycle, for example rigid PVC with soft TPE, so the gasket is formed together with the profile and needs no separate assembly.

What we make

Extruded profiles for refrigeration

Thermal-bridge profiles

Cross-sections with air chambers that limit heat losses in the most critical spots of refrigeration equipment.

Door profiles

A wide range of shapes for refrigeration doors, compatible with many glass pane and door system models.

Glass cover profiles

Profiles for in-store equipment that give easy access to the product and a clear presentation.

LED profiles

Profiles for LED strips in various shapes and sizes, easy to match to the fittings in use.

What you gain

Why extrude with us

Repeatability and precision

Lines with automatic dimensional control keep the cross-section within tolerance across the whole run.

A continuous process

Extrusion runs without interruption, so short lead times are possible even at high volumes.

Co-extrusion

We combine two polymers in one cycle – rigid PVC with soft TPE, or layers with different properties.

Any length

We cut the profile to the length given by the customer, in very long or very short versions alike.

Through-colouring

Pigments are added during plasticising, so the colour is permanent and does not rub off the surface.

Ready for further processing

We prepare the profiles for the next steps – cutting, batch marking or welding.

Production process

From the cross-section design to a finished profile

Extrusion is a continuous process – we plasticise the granulate, force it through the forming die, cool it and cut it to length.

From the cross-section design to a finished profile
  1. Cross-section design

    Our engineers prepare drawings and models of the profile, including complex multi-chamber cross-sections.

  2. Plasticising the granulate

    The granulate is heated to the temperature at which the plastic forms a homogeneous, mouldable mass.

  3. Adjusting the composition

    Additives that influence the colour and properties of the finished profile are mixed into the plasticised material.

  4. Extrusion

    The molten plastic is forced continuously through the forming die, which gives it its cross-section.

  5. Cooling

    The profile is cooled with nozzles to fix its shape and achieve stable dimensions.

  6. Finished product

    The profile is cut to length, marked with the batch number and prepared for further processes.

Ask a question
What is plastics extrusion?

It is a continuous forming process in which plasticised material is forced through a die that gives it a constant cross-section. This is how rigid PVC profiles, soft PVC gaskets and parts combining both materials are made.

What is co-extrusion?

Co-extrusion combines two or more plastics in a single cycle. Most often we join rigid PVC with soft TPE, so the gasket is formed together with the profile and needs no separate assembly.

Which materials do you extrude?

We work with rigid and soft PVC, TPE, ABS and PP. The material is matched to the operating temperature, the required stiffness and any food-contact requirement.

Will you make a profile to my drawing?

Yes. We extrude profiles from the customer's drawing, and where there is no drawing our engineers design the cross-section from scratch, based on a sample or a description of the application.

Can the profile be coloured?

Yes. Pigments are added while the plastic is being plasticised, so the colour runs through the whole cross-section and does not rub off the surface.

How long can the extruded profiles be?

The process is continuous, so in practice length is limited by transport and packaging. We cut the profile to the length stated in the order.
