  • Centrifuge casting device
    Patent number: 7934535
    Abstract: A centrifugal casting method and apparatus for casting molten metal into a mold. The casting apparatus includes a housing provided with a bottom surface and a retaining wall for minimizing a number of projectiles that escape the housing during casting operations. A prime mover is provided for imparting a centrifugal force on the molten metal, and an arm is coupled to the prime mover adjacent to a proximate end to be rotated about a rotational axis and to support a cradle for receiving the mold adjacent to a distal end. A crucible is to be coupled to the arm for supporting the molten metal to be cast into the mold, while a catch surface is disposed between the arm and the bottom surface of the housing to collect molten metal that is cast but not received within the mold.
