HIGH-PRESSURE DIE CASTING

This is our core expertise and great passion, even for small series

In HPDC, a liquid non-ferrous metal alloy is conveyed at high speed into a permanent metal mould. The alloy then solidifies in the mould cavity under a high and adjustable pressure. The liquid metal is fed via a dosing device, which takes the corresponding quantity from a crucible furnace provided for this purpose. The dosing takes place in the filling opening of the casting chamber, in which the metal is then gradually accumulated by a casting piston. This is followed by the actual mould filling. Once filling is complete, a certain dwell time elapses during which the alloy cools down sufficiently for the casting to be ejected and removed from the machine after the mould has been opened. After applying a coating as a release layer to the mould surfaces, the cycle starts all over again.

With die casting machines of different sizes and a unique variety of alloys, we produce exactly what you want from molten metal: a customised casting.
We use modern and fully automated casting cells to produce die-cast parts of varying complexity with consistent quality. At the heart of this is our automated machinery with our high-performance die casting machines, which have clamping forces of 1,250 kN to 6,800 kN (old designation: 125 - 680 tonnes). This enables us to produce a wide range of castings with dimensions from 3 x 3 x 3 mm up to 350 x 300 x 300 mm. We regularly process nine different alloys and can produce castings with a unit weight of 0.001 kg to 12 kg.
