摘要： 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.
