Centrifugal Castings

Centrifugal castingCentrifugal casting is a method of utilizing centrifugal force to produce castings from a rubber mold. It is used to cast small precise parts. Typically, a rubber disc-shaped mold is spun along its central axis at a set speed. The molten lead is then poured in through an opening at the top-center of the mold. The filled mold spins as the metal solidifies. Irregularities and spurs are thrown to the surface of the part, which can be machined away.

Centrifugal casting, also called spin casting, is used for cylindrical-shaped objects or machine fittings where the grain, flow, and balance are important to the durability and utility of the finished product.

  • Parts can be made in many lengths, thicknesses and diameters.
  • Different thicknesses can be produced at once from the same mold.
  • Multiple parts can be cast at once for speed.
  • Can eliminate the need for cores.
  • Excellent for repeat precision parts.

Custom rubber molds are created for each cast part. Multiple parts can be cast at one time in the same mold allowing for mass production of a piece. Centrifugal casting can be very time efficient for creating very precise custom pieces.
