  • Patent number: 5896912
    Abstract: A mold for gravity casting vehicle wheels having reusable thermally insulative linings attached to the interior of the gate and ball riser cavities. After filling the mold with molten metal, the gate cavity can be pressurized to assure that the mold cavity is completely filled. The ball riser cavity also can be pressurized subsequent to the gate cavity pressurization. The pressure on the gate and ball riser cavities forces molten metal from the cavities into the mold cavity as the metal cools and solidifies.
