Summary:Producing a mold, preferably a casting core or a casting mold, from a curable molding material, preferably a molding sand, comprises: mixing the molding material with electrically conductive particles; converting the molding material into its final mold; and hardening and drying the electrically conductive particles mixed with the final mold, preferably the casting core or the casting mold, by heating through induction. Independent claims are also included for: (1) a molding material, preferably a molding sand or a binding agent, mixed with electrically conductive particles; and (2) the mold, preferably the casting core or the casting mold, produced using the molding material, where the electrically conductive particles of the mold, preferably the casting core or the casting mold is heated by induction and thus the mold is hardened and dried. Die vorliegende Erfindung betrifft in erster Linie ein Verfahren zum Herstellen einer Form, insbesondere eines Gießkernes oder einer Gießform, aus einem aushärtbaren Formwerkstoff, insbesondere einem Formsand. Erfindungswesentlich ist dabei, dass - dem Formwerkstoff elektrisch leitende Partikel beigemengt werden, - der Formwerkstoff in seine endgültige Form gebracht wird, - die elektrisch leitenden Partikel und damit die Form, insbesondere der Gießkern oder die Gießform, mittels Induktion erwärmt und dadurch gehärtet und getrocknet werden. Hierdurch lassen sich auch geometrisch komplizierte Formen, insbesondere Gießformen, gleichmäßig aushärten und trocknen und damit in hoher Qualität bei gleichzeitig geringer Taktzeit herstellen. Zudem entfallen teure und unter Umständen ineffektive Heizeinrichtungen.
