High Pressure Die Casting Plant DAK1100 (Frech)

The high-pressure die casting process

In the High Pressure Die Casting process (HPDC), the liquid casting metal (i.e. aluminium or magnesium alloys) is pressed into a steel mould by a piston at very high speed and under very high pressure. The filling time is between 0,2 and 0,4 seconds and the specific casting pressure can be up to 1000 bar. In the cooled mould the metal solidifies very quickly, and the casting part can be removed after a relatively short cooling period.

The process is carried out automatically and thus offers a maximum productivity. The high mould costs are calculated for large quantities, which is nearly always the case in the fields of HPDC application (automobile construction, mechanical engineering, equipment technology, etc.).
