The Rubber to Metal Bonding Process
The rubber to metal bonding process provides a superior mechanical bond of rubber to metal parts or inserts. Integral to the process is a two-step preparation of the metal for rubber molding. First, the metal must be degreased, similar to metal coating or paint preparation, and cleaned of any contaminants. Next, a special, heat-activated adhesive is uniformly sprayed onto the metal parts.
Ready for rubber overmolding, the prepared metal parts are inserted into the mold cavity. Held in place by special magnets or chaplet pins, the mold is closed and the rubber molding process begins. The heat required to cure the rubber, activates the adhesive forming a mechanical bonding of rubber to metal.
Rubber insert molding completely encapsulates the metal part with rubber by suspending the metal insert in the mold cavity. Rubber can also be molded to a specific area of metal parts. Mechanically adhering rubber to metal can enhance the stability of metal parts with the flexible characteristics of rubber. Metal parts with molded rubber can improve part properties such as seals to NEMA standards, electrical conductivity, noise and vibration isolation, wear and impact resistance, chemical and corrosion resistance and more.
Steel, brass, aluminum, exotics, engineered resins and plastics can all be overmolded with rubber.
Medical rubber to metal bonded parts range in size from small inserts to large transportation components. Overmolded rubber metal parts are utilized across a broad range of applications, shapes and sizes such as bumpers, shafts, rollers and isolaters.
