Abstract

A method for producing a cast aluminum component having at least one reinforcing element arranged therein includes producing a core by placing at least one reinforcing element in a first mold and at least partially overmolding the at least one reinforcing element with a foam material. In the alternative, or in addition to, a core is produced by surrounding an inner element composed of a foam material by at least one reinforcing element. The method includes placing the core in a second mold and pouring liquid aluminum into the second mold and overcasting the core such that the liquid aluminum at least partially surrounds the core and the foam material is at least partially removed during the overcasting.
