Method and device for molding particularly of a metallic glass

A device to produce a part by molding a bulk metallic glass (BMG), comprising:

• a mold comprising two dies delimiting a sealed molding cavity;
• a melting device to melt the BMG comprising:
• a cold sectorized crucible, or melting crucible, arranged vertically comprising hollow sectors formed from an electrically conductive and non-magnetic material electrically insulated from one another;
• an inductor in a form of a coil surrounding the melting crucible to heat a content in the melting crucible;
• a current generator to generate an alternating current of a frequency between 10 KHz and 200 KHz to power the inductor;
• and
• an injection crucible to connect the content of the melting crucible with the sealed molding cavity to enable casting of the BMG;
• and
• a sectorized piston comprising hollow sectors made of an electrically conductive and non-magnetic material electrically insulated from one another, one end of the sectorized piston closing the melting crucible, and the sectorized piston is configured to circulate currents, induced by an alternating magnetic field of the inductor powered by the alternating current of the current generator, in the hollow sectors of the sectorized piston to generate a force to repel the BMG located in the melting crucible from a surface of the sectorized piston.
