Abstract

Cores that are inserted into the die when die-casting workpieces from metal, in order to maintain the cavities that are intended in the workpieces when the moulds are filled with the molten metal, have to meet high requirements with regard to their dimensional stability and the ease with which they can be removed from the cavities. According to the invention, salt-based cores are therefore provided which can be produced by moulding and compacting a core material mixture, the core materials thereof being selected from at least one salt, at least one binder and optionally from auxiliaries such as additives, fillers, wetting agents and catalysts, wherein the salt, the binder and the optionally used auxiliaries of the core material mixture are inorganic and said core materials are soluble with water as a solvent.
