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 ...
To ensure replicable casting cycles of accurate reproductions with a high quality finish, the spin casting process requires casting materials with the following qualities, for the following reasons: Low temperature operation - Spin casting is a low temperature process, as overexposure to high temperatures causes the rubber mold to degrade.
Centrifugal casting is a metallurgical manufacturing process by casting that may refer to either: Centrifugal casting (industrial), on an industrial scale; Centrifugal casting (silversmithing), for a smaller scale; See also: Spin casting

Lost wax casting can be dated back to 4000 BC or the Chalcolithic period. [4] One of the oldest studied examples of this technique is a 6,000-year old amulet from Indus valley civilization. [9] India is attributed as one of the first civilizations to use casting methods to mass produce coins.
Inlet-outlet cover of a valve for a nuclear power station produced using investment casting. Investment casting is an industrial process based on lost-wax casting, one of the oldest known metal-forming techniques. [1] The term "lost-wax casting" can also refer to modern investment casting processes.
