Abstract

The invention provides a method with which high-quality complex-shaped castings can be manufactured and with which, after the end of the casting process, the casting mould parts can be easily removed out of or from the casting without any risk. To achieve this the following steps are carried out: Manufacture of a mould material by mixing of a basic mould material, inert in comparison with the molten metal and pourable, which under heating expands less than quartz sand, and a binding agent, which under heating expands differently in comparison with the basic mould material, the manufacture of a casting mould part from the mould material, assembly of a casting mould making use of the casting mould part, pouring of the molten metal into the casting mould to form a casting, cooling of the casting over a solidification and cooling period, in which the casting mould part disintegrates self-actingly into fragments, removal of the fragments of the casting mould part from or out of the casting, and reprocessing of the fragments of the mould material to form a pourable basic mould material.
