The invention relates to a casting machine system comprising a first casting machine (1) and a separate second casting machine (2), wherein the first casting machine is a metal-casting machine and the second casting machine is a plastic-casting machine or the first casting machine is a plastic-casting machine and the second casting machine is a metal-casting machine, and to an associated process for producing hybrid metal/plastic components. A casting machine according to the invention comprises a transfer device (6) for transferring a precursor product (4), produced by means of a first casting process in the first casting machine, to the second casting machine, in which transfer device (6) a hybrid metal/plastic component is formed from the precursor product by means of a second casting process, and also a temperature control device (6) for controlling the temperature of the precursor product after it has been removed from the first casting machine and before the second casting process has started. The invention also relates to the use of the casting machine system for producing hybrid metal/plastic components.
