Abstract
Improved process for the centrifugal casting of parts with an irregular shape, involves the prior mfr. of a pre-coated sand cartridge used as a hot chamber or mould, the cartridge being located in a cone mounted in the centrifugal casting machine and employed to form the outer surface of the centrifugal casting. Pref. the sand cartridge has a conical outside dia. and a bore with a profile to match that desired on the outer surface of the casting, so that part of the surface of the casting so that part of the surface of the casting requires no machining, and the remaining parts possess only a min. amt. of material which is to be removed by machining. The cartridge may consist of one or more segments. Used e.g. in the mfr. of cylinder liners for internal combustion engines. The use of the sand cartridge permits the prodn. of castings with an irregular outer profile so that the amt. of machining required is reduced to the min. and a redn. of 35% in mfg. costs achieved.
