In centrifugal casting, a permanent mold is rotated continuously at high speeds (300 to 3000 rpm) as the molten metal is poured. The molten metal spreads along the inside mold wall, where it solidifies after cooling. The casting is usually a fine-grained casting with an especially fine-grained outer diameter, due to the rapid cooling at the ...
Generally, the casting materials used for competing processes like metal die casting and injection molding are similar, but not suitable for spin casting. For example, a typical zinc die-casting alloy such as Zamak 3 can be used but will solidify too rapidly from a molten state when cast with centrifugal force.
Centrifugal casting is a metallurgical manufacturing process by casting that may refer to either: Centrifugal casting (industrial), on an industrial scale;
Centrifugal casting (industrial) – Casting technique that is typically used to cast thin-walled cylinders; Core plug – Closure for sand casting core holes on water-cooled internal combustion engine blocks; Die casting – Metal casting process; Glass casting – Process for making objects from molten glass
Permanent mold casting is a metal casting process that employs reusable molds ("permanent molds"), usually made from metal. The most common process uses gravity to fill the mold. However, gas pressure or a vacuum are also used. A variation on the typical gravity casting process, called slush casting, produces hollow castings.

In Goldens’ centrifugal casting process, molten iron is poured into a hollow cylindrical mold spinning on a horizontal or vertical axis at speeds generating 40 to 70 Gs of centrifugal force. This force distributes the molten metal, promotes directional solidification, and improves casting integrity by forcing impurities to the inside surface.
Centrifugal casting, or centrifuging, [1] is used as a means of casting small, detailed parts or jewelry. [2] An articulated arm is free to spin around a vertical axle, which is driven by an electric motor or a spring. The entire mechanism is enclosed in a tub or drum to contain hot metal should the mold break or an excess of metal be used.
