Raw material is split into magnesium and aluminum alloys. For all materials uniform melting methods are applied facilitated by regular furnace cleaning intervalls to ensure cleanliness of the liquid. The appropriate alloy composition is crucial to ensure proper casting conditions to reach the required quality level.


Aluminum is melted in central gas-fired melting furnaces with about 760 °C. After an appropriate spectral composition test, the melt is filled into pre-heated transport containers before undergoing thorough cleaning. The cleaned melt is then transported to the respective casting cell via forklift and filled into the dosing furnaces. The liquid metal is kept constantly at about 700 °C. Upon signal activation by the casting machine the desired quantity of liquid metal is poured through the furnace by air pressure loading into the casting chamber. Process parameters such as melt temperature and dosing quantity are measured online and adjusted electronically during the process.

Magnesium is melted electrically directly at the die casting cell. From the multi-chamber furnaces with separate melting and dosing chambers magnesium is poured into the casting chamber through pumping. This is due to the reactivity of the liquid magnesium under protective gas and ensures compliance with the highest safety standards for equipment and operators.
