ABSTRACT:
A novel casting method is provided which includes a shell mold having a cope and a drag, which abut together along substantially planar mating surfaces and define a casting cavity between the cope and drag. At least one core is positioned within the casting cavity and includes at least one and preferably two crush pads each having a cam surface. As the cope is positioned onto the drag, the cope engages the crush pad cam surfaces and cams the core flatly against the shell mold.
