Tank furnaces are designed to keep die-casting Aluminium alloys warm. A refractory lining and high quality insulation are the reasons for low power consumption which results in low operational costs. Further advantages are: easy cleaning of the melting bath and durability of the tank. The highly efficient and long-lasting heating elements, which are integrated in the cover, heat the furnace. The activation of heating elements occurs via solid state relays, which keep the temperature of the melting bath free from overheating. The easy-to-move cover provides good access to the melting bath and therefore simple maintenance is possible This kind of furnace can also be equipped with more chambers in case of higher demands in melt.

The dosing system consists mainly of a vacuum ceramic container, an evacuation device to draw in melt as well as a special closing mechanism at the suction point. The vacuum container is made of ceramic with the benefit of: non-wettable, thermal shock resistant and strong. The mechanical movement occurs via a servo-controlled lifting or pivoting device.
The system shows following advantages:

• Drawing in of melt below bath level – no oxide
• Filling of container by sucking in melt – degassing
• Transfer of melt without air admission – no oxide
• Transfer of melt into a closed ceramic container – low drop of temperature
• High dosing precision through integrated, precise quantity measurement

The MDF is designed to melt magnesium alloys and keep them warm, enabling a safe and precise dosing of the molten metal into the cold chamber die-casting machine.
The MDF is produced as a crucible furnace with three heating racks. Our established furnace technology ensures the highest level of performance. The even distribution of the heating across the entire crucible minimizes thermal pressure on individual areas.
The crucible, insulation and heating mechanisms are therefore subject to reduced strain, increasing operational lifespan. The dosing occurs through a mechanical pump and a pivotal dosing channel. Surface level fluctuations in the bath as a result of the loading process are compensated for by the dosing system, ensuring exact dosage.

 Runners and defective parts accumulate in foundries. This material can be economically recycled in a modern, central in-house recycling system. High external recycling costs, storage and transport costs can be prevented. The process starts with the collecting and feeding of the recycling material by use
the feeding conveyor belt FCB, afterwards the melting in the Zinc remelting furnace ZRF and ends with liquid transport ZTF to the machine furnace or with the production of ingot via the ingot casting device ICD.
