The invention relates to a module (1) for a die-casting device, comprising a base (2) which can be fastened to a mounting plate of the die-casting device, a screw/cylinder unit (3) for producing a thixotropic material, and a filling chamber (4), wherein the screw/cylinder unit (3) and the filling chamber (4) are arranged indirectly or directly on the base (2) such that thixotropic material produced by the screw/cylinder unit (3) can be conveyed into the filling chamber (4).

A hot metal supply injection method includes generating a negative pressure in a cylindrical container by a negative pressure generation device, and causing molten metal to be sucked into the cylindrical container from a retention furnace, while keeping an opening portion of the cylindrical container immersed in the molten metal, arranging the opening portion of the cylindrical container in a gate of a cavity while holding the negative pressure by closing up the opening portion of the cylindrical container after moving an inner plunger tip to a tip side of the cylindrical container, and moving the inner plunger tip to a rear end side of the cylindrical container, then moving an outer plunger tip, together with the inner plunger tip, to the tip side of the cylindrical container, and filling the interior of the cavity with the molten metal through injection via the gate.

A die-casting machine has a casting mould, a casting chamber, a casting piston arranged in an axially moveable manner in the casting chamber, a melt inlet channel which leads into the casting chamber, a shut-off valve in the melt inlet channel, a melt outlet channel which leads from the casting chamber to the casting mould, and a control unit for controlling the casting piston. For carrying out a respective casting process, the die-casting machine is configured, for a mould-filling phase, to bring the shut-off valve into a closed position, and to control the casting piston in the casting chamber to advance from a casting start position to a filling end position, in order to press melt material into the casting mould via the melt outlet channel, and, for a subsequent refilling phase, to bring the shut-off valve into an open position and to control the casting piston to move back to the casting start position, in order to supply the casting chamber with melt material via the melt inlet channel. A closure nozzle is provided in the melt outlet channel. The machine is configured to keep the closure nozzle closed in the refilling phase and, in the mould-filling phase, with the shut-off valve remaining closed, to firstly move the casting piston back from the casting start position to an additional stroke position and to subsequently advance it from the additional stroke position via the casting start position to the filling end position, and at this time to keep the closure nozzle closed during the return movement of the casting piston to the additional stroke position and to only open it when the casting piston advances again.

A device to produce a part by molding a bulk metallic glass (BMG) includes a mold, a melting device to melt the BMG and a sectorized piston. The mold includes two rigid sections delimiting a molding cavity. The melting device includes a cold sectorized crucible or melting crucible, an inductor and a current generator to generate a high-frequency current to power the inductor. The melting crucible is arranged vertically having hollow sectors formed from an electrically conductive and non-magnetic material electrically insulated from one another. The inductor is in the form of a coil and surround the melting crucible to heat the content thereof. The sectorized piston has hollow sectors formed from the electrically conductive and non-magnetic material electrically insulated from one another, closing the melting crucible at one of the ends thereof.

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.
