An installation for producing cast products includes a tempering machine for at least some of the casting mass, a storage container for the casting mass, a casting machine, and a device for further processing the cast products. At least some of the casting mass is fed to the storage container from the tempering machine, depending on at least one controlling or regulating signal which is based on current and/or expected consumption of casting mass by the casting machine and/or the casting installation. As a result, the installation can be operated at lower cost and extreme fluctuations in the filling level of the storage container can be better prevented, avoiding interruptions in the supply of casting mass to the casting machine.
