Abstract

Foundry cores, which consist of a mould material mixed from a binder and a mould sand, as well as optionally added additives, that are moulded in a complex way or are optimised with regard to their quality and which are provided for casting cast parts, can be produced by: a) moulding the foundry core by introducing the mould material into a foundry core mould; b) hardening the mould material; c) removing the foundry core from the foundry core mould; d) heating the foundry core to a deformation temperature; e) deforming the heated foundry core by applying a deformation force to the foundry core; and f) cooling the foundry core.
