ABSTRACT:
Prevention of fins during a metal casting process is achieved by employing a mold having at least one protuberance along a parting line of the mold and a film of soft plastic covering the mold including the protuberance. When the mold is pressed against another mold the protuberance is held in place by the film of soft plastic. The pattern for forming the mold includes a shielding mold member of a soft plastic film formed over an inversely drafted part along a parting line of the pattern. The mold can also be formed from a pattern having a shielding mold member of a soft plastic film formed over at least one recess in a parting line of the pattern.
