ABSTRACT:
Casting apparatus comprises a vacuum box having a pair of laterally spaced side walls sealingly engaged to a pair of pick-up members disposed along laterally spaced apart sides of a casting mold. The vacuum box also comprises a pair of spaced end walls sealingly engaged to the casting mold. Sealing engagement of the laterally spaced vacuum box side walls to the pick-up members, rather than to the mold, permits a substantial reduction in the lateral dimension of the mold, thereby substantially reducing the amount of costly mold material (e.g., resin-bonded sand) needed to fabricate the mold for casting and to be disposed of after casting.
