Abstract
A process produces a composite cast part containing an insert part and casting material. The insert part is integrally bonded to the casting material. The process includes: producing the insert part formed of an exothermic material; encapsulating or embedding the insert part; inserting the encapsulated/embedded insert part into a casting mold; filling the mold with molten mass; and flowing a casting material on the insert part. The exothermic material ignites through contact with the flowing casting material or as a result of the ignition temperature of the exothermic mass being reached, whereby a temperature gradient between the cast material solidifying molten mass the insert part is reduced.
