摘要

Producing a feed part for a composite casting part, comprises providing (10) a mold for setting an outer contour of the feed part, producing (14) at least one core for setting cavities in the feed part, inserting (16) at least one core into the mold and casting (18) a material into the mold. The method comprises incorporating (14) a molding into the core during production of the core. The molding represents a part of a contour of a connecting element of the feed part deviating in an area from a surface of the feed part for a casting connection with another part of the composite casting part. Producing a feed part for a composite casting part, comprises providing (10) a mold for setting an outer contour of the feed part, producing (14) at least one core for setting cavities in the feed part, inserting (16) at least one core into a mold and casting (18) a material in a fluid state into the mold. The method comprises incorporating (14) a molding into the core during production of the core. The molding represents at least a part of a contour of a connecting element of the feed part deviating in an area from a surface of the feed part for a casting connection with another part of the composite casting part. An independent claim is also included for producing the composite casing part, comprising at least partial overcasting of the feed part, where at least the connection element of the feed part is overcast or filled.
