Centrifugal Casting is the process in which molten metal
is poured into a spinning die that rotates at several
hundred rpm. The metal is centrifugally spun towards the
inside die wall, where it cools and solidifies. The resulting
casting is a fine grain tube that can be subsequently machined
to produce a variety of cylindrical parts. During the
centrifuging process, the pure metal is spun to outside of the
casting, leaving any impurities on the inside diameter, which
are then machined away. The centrifugal process produces a more
consistent microstructure and typically has fewer issues with
porosity than static casting.
Quaker City Castings can produce centrifugal castings up to 13" outside diameter in all the materials we pour in our sand-casting operations, including gray iron and ductile iron, steel, stainless steel, carbon steel, heat-resistant steel, and superalloys. Some of the finished parts we produce include cylinder liners, lapping pots, various ring products, bushings, and bearings.
