Rubber to metal bonding

Rubber to metal bonding

Reduced assembly times and improved performance

In the world of rubber mouldings, a rubber part that has been ‘bonded’ means that a metal component has been chemically prepared and attached or encapsulated as part of the vulcanisation process to become a bonded rubber part.

The basic rule of thumb when it comes to bonding rubber to metal is that if you have a rubber part which needs to adhere to a metal part, or which is part of the same assembly, a vulcanised bond will be far superior than any adhesive. In fact, looking at the destructive tests that we’ve run, the rubber itself is more likely to break apart than the bond between the metal and the rubber. You don’t get much more integral than that and this is what makes us experts at bonding rubber to metal. You can learn more about the technical details around the process of bonding rubber to metal by reading our blog posts,

The other benefits of bonding rubber to metal is that it avoids fitment problems (seals can be fitted the wrong way round in error) and reduces assembly time by combining two components. This makes the bonded rubber part more stable and secure.

Rubber to metal bonding

We are experts in bonding rubber to metal

People have been bonding rubber to metal for over 100 years, but thanks to innovations and developments we are able to bond rubber to just about anything. We use suitable preparation processes, primers, bonding agents and tool designers to bond rubber to metal. This means that we are able to provide the best of both worlds: flexibility and strength, with sealing and support. Find out more about our rubber bonding capabilities by heading to our rubber bonding page.
