Aluminum-die-casting is defined as a pressure-casting-process, where aluminum is pressed in the liquid-or pasty state under high pressure into a preheated-steel-mold. It displaces the existing
air in the form and is maintained under pressure during the solidification process. The permanent mold made of steel is increased by the shrinkage exact negative of the casting. The form consists
of two halves (possibly additional slide), so that it is opened after the filling and solidification of the metal , and the casting can be removed from it. In principle aluminum-die-cast can only
be produced on cold-chamber-die-casting-machines.
