Rubber to Metal Specialists
Pierce-Roberts Has Been Here Since the Beginning
During the molding process, rubber to metal bonding occurs when the rubber is chemically bonded to a metal insert. To prepare the inserts for production before the adhesive is applied, a degreasing system is used to rid the parts of any contaminants. The inserts are then grit blasted followed by an additional cleaning. The heat activated adhesive is later applied to the inserts using a technique similar to spray painting. Once the preparation process is complete, the metals are ready for production.
Production
During the production process, the inserts are placed into each cavity of the mold one at a time. Once in place, the rubber molding process gets underway. The adhesive is then activated once the mold is closed, allowing the rubber to bond to the inserts.
The generic phrase, vulcanized bonding of rubber to metal, comprises all aspects of the bonding process, in turn chemically bonding an elastomer to a pre-coated steel surface. Rubber to metal bonding is incredibly useful for products requiring steel strength all while remaining as flexible as rubber.
Ranging from an anti-way bushing inside the cabin of a locomotive, to an air poppet or small motor mount, many rubber components require rubber to metal bonding.
