What is a silicone extrusion?

Silicone rubber extrusion is the process of creating parts with a continuous cross-sectional shape from uncured silicone rubber compound – this is done by pushing the material through a die to form the shape and then curing it with hot air.

The types of products created by rubber extrusion include rubber profiles, tubing, strips, cords, and much more. There are numerous benefits and uses of rubber extrusions, stretching across multiple industries, some of which we will discuss in this article.

Common uses of silicone rubber

As mentioned, silicone extrusions are used in a wide range of applications around the world, with silicone rubber being the material of choice for many industries, providing numerous benefits and advantages.

Some of the industries that use silicone rubber the most include the:

  • Food industry
  • Medical industry
  • Automotive industry
  • Construction industry

These are just a handful of industries that use rubber extrusions every day. 

Some of the most common applications for rubber extrusions include oven seals and baking mats due to their heat-resistant qualities, transition seals to effectively seal construction materials together, and car gaskets to reduce the frequency of replacements.

The silicone rubber extrusion manufacturing process

When manufacturing our silicone rubber extrusions, we undergo thorough and strict checks to ensure the top quality and reliability we are known for. We have worked tirelessly to ensure we have as efficient a process as possible, complying with all industry regulations and standards, with safety and reputation at the forefront of everything we do.

Below, we have outlined our manufacturing process and why this makes us the go-to destination for rubber extrusions in the UK:

Step 1 – Milling

The silicone compound is mixed in an open mill with the catalyst, pigment and any additives required to give it the desired performance characteristics.

Step 2 – Extrusion

The silicone is fed through a die to form the required shape using an extruder. The shaped material then passes on a conveyor belt through a hot air oven to cure the material. During this stage, regular checks are made to ensure the dimensional accuracy of the  being made.

Step 3 – Post Curing

After extrusion, the cured parts are then post-cured in an oven for 8 hours at 200°C.

Step 4 – QA

All items are subject to a final round of QA, where the materials, colours and dimensions are checked before being signed off.

Step 5 – Packing and Dispatch

Items are then packaged – ready to be sent to the customer.

This process has allowed us to become one of the leading rubber extrusion manufacturers and suppliers in the UK, dealing with hundreds of customers across the country, spanning a wide range of industries and sectors.
