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.
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 ...
Precision Castparts Corp. is an American industrial goods and metal fabrication company that manufactures investment castings, forged components, and airfoil castings for use in the aerospace, industrial gas turbine, and defense industries.
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.

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.
The company was originally founded by Adamo Pasotti in 1944 or 1946 with the factory located on via Triumplina in Brescia. [3] By 1956, Idra was seeking to export its die-casting machines outside Italy. [4] By 1971, an Idra OL-1200 S machine was being used to cast motor components weighing 7 kilograms (15 lb) for Porsche cars. [5]
