Centrifugal casting, also known as rotocasting, is used to cast metal into cylindrical parts. For centrifugal casting, a permanent mold is spun around a central axis at speeds up to 3,000 rotations per minute. Molten metal is poured into the mold, where centrifugal forces throw it against the walls of the mold. As it hits the walls, it cools, causing the object being formed to solidify from the outside in. Centrifugal casting can produce parts up to 15 feet in length and 10 feet in diameter. Metals that can be used in centrifugal casting include aluminum alloys, stainless steel, iron, nickel, bronze, and copper. Specific parts that can be made using centrifugal casting include tubes, rings, nozzles, coils, bearings, and pulleys.
Because impurities rise to the inner surface of the part being cast, objects created using centrifugal casting typically need further machining, grinding or polishing to smooth out imperfections on the inner surface before being used. Therefore, it is not a good choice for parts that are intended to be ready to use immediately after manufacture.
