Silpro Extrusions specialise in the production of custom extrusions.

Using wire EDM we able to cut your designs from sketches or CAD drawings into inexpensive dies enabling us to produce prototypes at affordable prices.

Several types of extrusion can be supplied with no tooling cost, where a tool is required a typical lead time is 10 working days from order.

General purpose grades can be offered in hardness ranges from 20° shore to 80° shore. Silpro also manufacture specialist silicone extrusions in compounds such as:-

  • High Tear Strength.
  • Semi-Conductive – Low volume resistivity
  • High Temperature – up to 300°C.
  • Anti-Microbial – effective against E-Coli & MRSA, prevents mould and algae growth.
  • Metal Detectable – FDA compliant for Food / Pharmaceutical applications.
  • Fluorosilicone – provides excellent chemical resistance.


Profiles / Extrusions

Silicone extrusion is the process whereby silicone rubber is forced through a shaped die with your chosen design to produce continuous square, rectangular strips, hollow shapes in a various silicone rubbers.

Silicone typically shows a huge improvement over other materials maintaining their functions at -60c to +300c – they last longer, come in a multitude of colours to RAL, Pantone, British Standards, or colour matched and will stand up to a wider variety of environmental conditions. We can produce simple extrusions, or supply custom profiles with fibreglass inserts in complex cross-sections.

Choosing the right profile

For material selection we can advise on which grade of rubber will be best for your application.

Have a look at our standard profile designs on our brochure for ‘D’ sections , flap seals, inflatable seals, ‘P’ tapes, and glazing channel seals to add to your owns ideas. These profiles can be supplied in coils, cut lengths or fabricated into rings of various sizes using silicone joining equipment. For prototypes we can sign non disclosure agreements with you to protect your projects.

Where you have a design in place, we can manufacture direct from your drawings or existing samples or products using reverse-engineering techniques.

Silpro and extruding

At Silpro Extrusions we pride ourselves on the quality of our extruded products, whether they are simple or complicated profile shapes. This has given our customers confidence and trust that whatever the profile shape we will consistently manufacture within the tolerances required for each and every order. We ensure you get the product you want when and where you need it.

We have the experience, know-how and on site facilities to get your product off the ground in a quick and efficient way, from responsive design service & small batch prototyping; right through to volume manufacturing.
