Abstract
A complex cast component of an internal combustion engine, in particular a crankshaft or a camshaft, has a longitudinal axis, a plurality of regions, along the longitudinal axis, and a first cavity. Each of the plurality of regions has a certain cool-down rate during a solidification process of a casting process. The first cavity is arranged in a first region of the plurality of regions and has a volume that depends on a first cool-down rate of the first region. In this way, a material thickness in the first region likewise depends on the first cool-down rate.
