Abstract
A method for producing cast items in a casting method, wherein a charge of a conductive material is introduced into the sphere of influence of at least one alternating electromagnetic field, so that the charge is kept in a levitating state. The melt is poured into moulds in order to produce turbine blades, prostheses or turbocharger impellers.
