Apparatus and method for producing a cast part formed from amorphous or partially amorphous metal, and cast part

An apparatus for producing a casting formed from an amorphous or partially amorphous metal, which comprises:

• a casting mold comprising a mold cavity and at least one filling opening for introducing a casting material forming the casting into the mold cavity;
• a device for melting the casting material, the melting device comprising at least one melting region in which to melt the casting material, at least two electrodes being arranged at a distance from one another, and at least one electric arc formed between the at least two electrodes, whereas a first one of the at least two electrodes has a fixed proximal end and a movable distal end, the movable distal end has a first extendable horizontal configuration and a second retracted horizontal configuration in the same horizontal plane, and whereas a second one of the at least two electrodes is at least partially formed by the casting material;
• and
• a casting plunger:
• the casting material being forced into the mold cavity by at least the casting plunger when the casting plunger is actuated in a downwards direction;
• whereas both the casting plunger and one of the at least two electrodes are arranged on the same side of the mold cavity in a single gas-tight housing, characterized in that the casting plunger, the casting mold and the at least two electrodes are arranged within the single gas-tight housing.
