ABSTRACT:
The cavity surface of a foam mold is sprayed with a paint which becomes integrally bonded to the outer surface of the foam molded part. The sprayed paint unavoidably overlaps the parting faces of the mold around the outer edges of the mold cavity. In order to avoid the necessity of trimming a paint flash from the molded part along a line corresponding to the parting line of the mold, after the cavity is spray painted and while the paint is still wet the line of intersection between the cavity and the parting faces of the mold is contacted with a member which interrupts the continuity of the paint film. This avoids the formation of the paint flash on the molded part.
