A goal of our developments is to provide cost advantages to the foundry. Either by reduction of the operating cost by remelting the biscuits and runners, or by supplying the ideal conditions for casting.

Remelting (recycling) in the central furnace (indirectly heated), prevents external recycling costs, including transport costs, temporary storage costs, and reduces crucially the costs of the storage of the raw material.

Remelted material is quality wise equivalent with new material and can be either automatically casted to ingots again, or - still more economically ? filled directly into the machine furnaces in liquid.

Ideal conditions for casting can be realized, if the zinc is available with constant level and constant temperature at the gooseneck chamber.

Rauch has already developed in the 1984 a machine furnace, which fulfilles both demands with two separated crucible chambers. The logical continuation of this is done by the connection of remelting and automated transport of the material to the machine furnaces. This is done with central remelting process as well.
