摘要

Production of cast parts comprises positioning open-pored lattice structures in a casting mold in regions of the cast part where defects may occur, and filling the casting mold with melt. Preferred Features: The open-pored lattice structure is made of the same material as the melt. The open-pored lattice structure is made of or coated or filled with a material having increased heat absorption and increased heat emission. The open-pored lattice structure is coated or filled with a material having increased gas emission or which can emit hardening substances. The open-pored lattice structure is used at a pre-determined temperature.
