ABSTRACT:
A combination of a rubber or other elastomer part and a plastic or metal part is bonded by both chemical and mechanical means. The mechanical means is in the form of molded rivets integrally manufactured in the molding process as part of the elastomer. Appropriate mating holes are made in the plastic or metal parts to receive the rivets during the molding process or at least before the rivets are cured. Conventional chemical bonding materials for the circumstance are employed with the rivet bonding to provide dual bonding strength. The parts of a blowout preventer, such as at the T-seal and the upper seal, are disclosed as preferred examples of locations that are subject to high pressure and temperature where an elastomer part is bonded to a plastic or a metal part.
