Rubber To Metal Bonding

What is rubber to metal bonding?

Rubber-to-metal bonding is a means by which rubber is mechanically bonded to a metal component during the moulding process. Each step is dependent on the success of those that preceded it and the stages are numerous and complex. DP Seals is a specialist in this area.

Why use rubber-to-metal bonding?

Some key reasons to use rubber-to-metal bonding include the following:

  • Any part which requires a combination of the flexibility of rubber and the stability of metal
  • Combining several parts into a single assembly
  • Ensuring critical functions will not fail due to a weak bond where they may if using a traditional adhesive.
  • Enhancing sound proofing and vibration control
  • Sealing against organic solvents, sea water and boiling water

What is the rubber to metal bonding process?

  1. Part design and geometry
  2. Preparing the part for maximum bond strength
  3. Application of primer and bonding agent
  4. Moulding
  5. Testing with prototypes or the finished part to ensure quality standards are met

Which metals can be bonded to rubber?

Due to the ingenuity and innovation of chemists and those in the industry throughout the years, today almost any metal can be bonded to rubber. However, each metal has a different chemical composition that can react to the type of rubber being used. Therefore an important step is to determine the best metal type and grade as well as the optimal rubber material for the application.

Precision in-tool rubber metal bonding

DP Seals produces a wide variety of rubber metal bonded seals and mouldings. We work for industries as diverse as aerospace, food & dairy, specialist automotive, instrumentation, electronics and motorsport.

We were one of the first companies to successfully bond Optimised HNBR to stainless steel. This means you can expect unrivalled materials knowledge and in-tool moulding expertise when you partner with us.

Solve your rubber to metal bonding problems

Got awkward production problems where other companies have failed? Our reputation for innovation and materials expertise has proved invaluable in the production of bonded seals. This is especially true where high performance and longevity in hazardous environments are of paramount importance.

A good example of this would be our work in specialised paper movement technology in the printing industry. Here we develop rubber rollers, bonded drive wheels and bobbins utilising specialist material blends. In this way we achieve exactly the right traction for moving paper through various printing processes.
