Producing bonded extruded gaskets is a complex process. We can supply seals with either a hot splicing or vulcanised joint. These are techniques that use heat, pressure and film splice or uncured rubber to join the ends of extruded rubber profiles.

Vulcanised joining is a reliable, cost-effective process for joining sponge or rubber profiles. Applications of vulcanised rubber extrusions include O-rings, tubing, rectangle/square profiles and are best suited for low volume quantities rather than high volumes.

Hot splicing uses thin film and either a conventional heat source or infrared (IR) light to produce a sound bonded seal.

Working in several sectors, rail, military, construction, and general engineering, we manage entire projects helping with design and choice of material. If you are looking to replicate an existing part, CB Frost can work with you to reverse engineer extruded rubber or sponge components, offering like for like or the same part in an alternative material, and have full prototype capabilities to cater for small / large volumes.
