ABSTRACT OF THE DISCLOSURE Sand molds stored in a prepour storage system are retrieved and conveyed to a pouring station with a total mold cavity capacity equal to the amount of molten metal to be poured. Despite the fact that the mold cavities vary in size they are delivered to the pouring station in a sequence that accommodates delivery of the molds having variable metal capacity to one of a plurality of cooling conveyor lines so that each cooling line conveys molds which require variable lengths of time to cool before such molds can be conveyed into a punchout where the cope flask is stripped and the sand mass and castings are pushed up from the drag flask and onto a shakeout which conveys sand to a reclaim system and castings to a processing area where the castings are shot blasted, gates and risers are removed, the castings are inspected, flame washed, welded (as needed), ground, chipped, heat treated and then blast cleaned a second time before final grinding, chipping, gauging, final inspection, assembly and storage. The mold flasks are cleaned, new mold cavities formed therein and are reassembled and then stored in the prepour storage system where their location is recorded by a computer for selective retrieval for the next heat to be poured.
