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 ...
In the 1920s, American developed a proprietary Mono-Cast centrifugal casting method and increased pipe diameters to 24 inches (610 mm). The company also introduced cement-lined pipe, which became the industry standard.

Spin casting, also known as centrifugal rubber mold casting (CRMC), is a method of utilizing inertia to produce castings from a rubber mold. Typically, a disc-shaped ...
Among the growing number of machinery manufacturing firms in Milwaukee in the 1870s was a struggling firm known as the Whitehill Sewing Machine Company. Alonzo Pawling and Henry Harnischfeger managed castings patternmaking and gear machining operations within the Whitehill factory. Concerned that Whitehill lacked the marketing and manufacturing ...

Precision Castparts (PCC) was founded by Joseph Buford Cox on April 1, 1953. [6] Cox was owner of Oregon Saw Chain and in 1949 had started a casting operation to make saw teeth with assistant general manager Ed Cooley also working on the project.
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.
