COMPONENTS – CRUCIAL FOR EVERY
INDUSTRY
Rubber to metal bonded components are extremely crucial for various industrial 
applications. Rubber to metal bonded components are made by ways of rubber to metal 
bonding. This is a process wherein a rubber part is combined with a metal part. 
Processes of Rubber to Metal Bonding
Rubber to metal bonding is generally done by two common processes. These are: 
 Transfer molding - In this method, the metal parts are inserted into a heated mold 
and the solid rubber then pushed into the mold. Thereafter, the mold is cured and 
vulcanized.
 Injection molding - This is similar to the transfer molding process but here, a metal
piece is first inserted into the mold and then a liquid elastomer injected into it. Once 
the mold is cured, the part is removed. 
Steps in Rubber to Metal Bonding
Rubber to metal bonding runs through several steps. These steps are:
 Elastomer preparation - The isolation mounts are generally made either with 
natural rubber or neoprene. For elastomer preparation, rubber latex and neoprene 
is combined with several kinds of fillers and other ingredients to get the desired 
properties.
 Surface preparation - In this step, a low carbon steel bonding surface is prepared 
to offer a good performance in bonding
 Primer and adhesive application - Once the metal components have been 
prepared, adhesives are applied onto them. Two coat adhesive system is the most 
common method used here. The primer is applied, thereafter.
 Molding process - In this step, a mold is heated and the metal components loaded 
onto them.
 Testing - Once the process of manufacturing is completed, the samples of rubber to 
metal bonded components of each lot are tested for their strength.
Alfa Rubber is one of the leading manufacturers of rubber to metal bonded components. 
The company makes such components for the automotive, agriculture, electrical, defense 
and general engineering industries.
