### Claim 9 (depends on 2)

The system according to claim 2, wherein the upper casting mold half is pivoted by up to 135°C.

### Claim 10 (depends on 2)

The system according to claim 2, wherein the upper casting mold half is pivoted down.

### Claim 11 (depends on 2)

The system according to claim 2, wherein the lower casting mold half is pivoted up.

### Claim 12 (depends on 2)

The system according to claim 2, wherein first and second casting apparatuses are provided, which are disposed adjacent one another, wherein a manipulator for handling work pieces or tools of the two casting apparatuses is disposed between the casting apparatuses.

### Claim 13 (depends on 2)

The system according to claim 2, wherein a first and a second valve, switched in parallel, are provided, in each instance, for supplying pressure to the lower chamber or the lower pressure space or furnace interior, and, if applicable, for supplying pressure to the upper chamber or the upper pressure space, the first valve being for main filling of the pressure space, and the second valve being for a more precise pressure adjustment within the pressure space, wherein the first valve is larger than the second valve.

### Claim 14 (depends on 13)

The system according to claim 13, wherein a pre-control is provided, in each instance, for regulating each valve, which control is implemented as a characteristic field or as a mathematical model.

### Claim 15 (depends on 2)

The system according to claim 2, wherein the intermediate plate or mold adapter plate has predetermined tempering channels that end in connectors disposed on the intermediate plate or mold adapter plate for tempering lines disposed outside of the at least one casting apparatus.

### Claim 16 (depends on 15)

The system according to claim 15, wherein each tempering line is individually controlled.

### Claim 17 (depends on 1)
