Abstract
Method and apparatus for casting a gasket into a cast member utilizing a one-piece mandrel assembly provided within a mold assembly. The resilient, compressible gasket is mounted upon the mandrel assembly during the casting operation. The mandrel assembly is withdrawn from the cast member after it has cured. The mandrel assembly may also be utilized to form a knockout barrier a pipe stop and a mounting fixture for mounting a baffle to the interior wall of the cast member through a snap on fastening arrangement. The mandrel assembly is preferably designed to facilitate stripping of the mandrel assembly from the cast member after the cast member is cured.
