ABSTRACT:
A assembly of mated molded parts and a method for making same are disclosed in which the assembly has first and second parts with precisely mating surfaces. The first part is formed by molding, casting, or the like such that the mating surface of the first part is formed with at least one protrusion. The second part is formed in place against the first part such precisely mating surfaces are formed with the second part enveloping the protrusion. The two parts thus formed are forced apart from each other. The protrusion may be formed with a head which interlocks with the second part. When the parts are separated, the head breaks from the protrusion. In a particular embodiment, a bearing cap is disclosed having a central opening for the passage of a shaft.
