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.

A system and method for manipulating or heating conductive material. The system comprises: a first electromagnet; a second electromagnet; the first electromagnet and the second electromagnet each comprising: a body; a first pole, the first pole proximal to a working surface; a second pole, the second pole distal to a working surface; a coil at least partially disposed around the body; a modulating controller configured to selectively apply a current to the first or the second electromagnet; the current configured to produce a time-varying flux density at the first pole; and a working volume in communication with the first pole. Manipulation of the material may be contactless and may include, but is not limited to, rotating, levitating, moving, and/or shaping the conductive material.

A method is used for producing metal sheets for packets of metal sheets of a rotor and of a stator for three-phase drives, in particular for reluctance machines (reluctance motors) made of magnetic, in particular magnetically soft materials by means of additive production processes, in which the magnetizable material is melted and fed to at least one print head which applies the melted material to form a rotor/stator sheet. The melted material is influenced by an applied magnetic field so that the finished rotor/stator sheet has an area with high magnetic conductivity determining the desired direction of flow.

The disclosure relates to a device for producing an investment casting component, comprising a melting chamber having an induction coil assembly disposed in the melting chamber, wherein the induction coil assembly is adapted to melt off an electrode at least partially received therein to produce a ceramic-free continuous melt jet having a melt flow rate MFR of at least 2.5 kg/min. The device further comprises a casting chamber downstream of the melting chamber and connected thereto, with an investment casting mold received or receivable therein for being filled by means of the ceramic-free, continuous melt jet.
