Abstract
A method of producing a precision centrifugal casting includes: a) providing a centrifugal casting device having a rotor rotatable around an axis, at least one crucible accommodated in the rotor, and at least one mold associated with the crucible and disposed at a first radial distance from the axis, b) creating a metal melt within the crucible, c) rotating the rotor thereby forcing the melt using centrifugal forces from the crucible into the mold, d) exerting a pressure on the melt forced into the mold until the temperature of the solidifying melt has reached a predetermined cooling-temperature in a range of 1300° to 800° C., wherein the pressure corresponds to the centrifugal force acting on the melt just when the mold is completely filled, times a factor of 1.0 to 5.0, and e) relieving the pressure when the temperature of the solidifying melt is lower than the predetermined cooling-temperature.
