Rubber Bonded to Metal & Plastic
Rigid parts with a flexible finish
Manville offers the ability to not just glue or adhere rubber to substrates, but to create a true vulcanized bond so tough and durable that the bond strength actually exceeds the strength of the rubber material. This type of bond is created with the metal or plastic parts being coated with rubber in situ in the mold during the rubber vulcanization. With this technique design engineers are able to combine rigidity, flexibility and resilience within a single finished component.
Manville Rubber Products can create strong, durable vulcanized bonds. We have decades of experience in bonding rubber to metals and plastics. We can work with metal or plastic inserts that you supply or we can supply machined or molded inserts to your specifications and provide you with complete finished assemblies.
Case Study: A Small Seal Derails A Big Project
Problem: A supplier to the aftermarket aerospace industry came to Manville Rubber with a small part that was creating a big problem. As a refurbisher of commercial aircraft galley and bathroom equipment, they were having trouble obtaining consistent sealing from a component controlling water flow in aircraft bathrooms. This small part was imperiling their effort to gain business as their refurbishments were deemed unsatisfactory.
Solution: We sat down with their engineers to clarify how the seals were failing. We quickly determined that the seal required extremely precise concentricity of rubber bonded to the stainless housing. This was not an ordinary seal, but their previous supplier was treating it as such. We proposed a unique fixture adapter that would allow us to locate the stainless housing within the mold cavity with the required degree of precision. We then fabricated a mold with the exact dimensional accuracy and finish quality.
Prototypes exceeded their expectations, and this sealing component has become a large part of our client's business. In the years since, we have assisted this client with other equally challenging projects, bringing success to all of them.
