Abstract
A method for casting metals under pressure by a cold-chamber method includes placing a bolt of the metal to be cast in one of at least two casting chambers and selecting a casting chamber from the at least two casting chambers and feeding and introducing the selected casting chamber into a diecasting machine, the selected casting chamber having one outlet opening. The selecting and feeding of the casting chambers is carried out alternately from the at least two casting chambers. The method further includes heating the bolt by means of induction. Melting of the bolt in the selected casting chamber is carried out after the feeding and introducing of the selected casting chamber into the diecasting machine but before an opening of the outlet opening of the selected casting chamber in order to fill the cavities is completed.
