Abstract
A process for producing a dimensionally accurate component from a nonferrous metal alloy includes the steps of: providing a casting mold corresponding to an external shape of the component and associated with an outlet opening, wherein the casting mold includes at least one heated mold shell; providing a heated rotatably mounted runner device for receiving a melt of the nonferrous metal alloy; determining a three-dimensional setting angle for the casting mold with respect to the outlet opening based on acceleration forces on the melt, wherein the acceleration forces include centrifugal forces applied to the melt and Coriolis forces of the centrifugal forces; disposing the casting mold at the three-dimensional setting angle with respect to the outlet opening; and feeding a melt into the mold through the outlet opening using the runner device so as to completely fill the casting mold.
