Centrifugal casting, sometimes called rotocasting, is a metal casting process that uses centrifugal force to form cylindrical parts.
This differs from most metal casting processes, which use gravity or pressure to fill the mold. In centrifugal casting, a permanent mold made from steel, cast iron, or graphite is typically used. However, the use of expendable sand molds is also possible. Pouring – Molten metal is poured directly into the rotating mold, without the use of runners or a gating system.
The centrifugal force drives the material towards the mold walls as the mold fills. Cooling – With all of the molten metal in the mold, the mold remains spinning as the metal cools. Cooling begins quickly at the mold walls and proceeds inwards. Casting removal – After the casting has cooled and solidified, the rotation is stopped and the casting can be removed.
Finishing – While the centrifugal force drives the dense metal to the mold walls, any less dense impurities or bubbles flow to the inner surface of the casting. As a result, secondary processes such as machining, grinding, or sand-blasting, are required to clean and smooth the inner diameter of the part. Centrifugal casting is used to produce axi-symmetric parts, such as cylinders or disks, which are typically hollow. Part size: Diameter: 1 – 120 in.

Actual capabilities are dependent upon the manufacturer, equipment, material, and part requirements. For investment casting in art, see Lost-wax casting. Investment casting is an industrial process based on lost-wax casting, one of the oldest known metal-forming techniques. The term “lost-wax casting” can also refer to modern investment casting processes. Investment casting has been used in various forms for the last 5,000 years. In its earliest forms, beeswax was used to form patterns necessary for the casting process.
