For the production via pressure diecasting, we are disposing of casting machines from 150 to 700 t closing pressure. This allows for the manufacture of aluminium parts with up to three kilos. A mechanical method like pressure diecasting ensures an efficient production of casting parts with a complex geometry, a high dimension accuracy and component strength.

Through heat-treatment, it is possible to establish certain characteristics (tensile strength, elastic limit, breaking elongation and abrasiveness) in pressure-casted aluminium parts. While chill- and sand-casted parts may undergo any heat-treatment without restrictions, only certain modern diecasting technologies e. g. vacuum-casting, enable a broad heat-treatment.
