Rubber Compression Moulding

Rubber Compression Moulding is where uncured rubber material is put into a mould cavity. Applying pressure and heat reforms the rubber, creating the new geometry. People often compare this process to waffle making.


Prototype, Batch & Mass Production

You can use multiple cavities to gain economies of scale. Making this process suitable for batch and mass manufacture. Prototyping rubber parts is also very suitable, as we can produce affordable moulds quickly.

Rubber Compression Moulding has relatively long cycle times in comparison to Injection Moulding. Where you could expect anything from 3 to 8 minutes. However you can offset this by using a larger number of cavities. For smaller items a 100+ cavity tool is not uncommon.

Typical parts made by this process include:

  • Rubber Grommets
  • Seals & Gaskets
  • Rubber Mats
  • Rubber Feet
  • Keypads
  • Buttons
