Method for determining an actual volume of a die casting mass in a die casting process

摘要

Method for determining an actual volume Vr of an injection-cast mass during an injection-casting process, in which the injection-cast mass is introduced into at least one cavity of a molding tool, having the steps of: a) determine a theoretical volume Vt from process variables at least during a filling phase of the injection molding process, b) determine and / or measure at least one value for at least one mass pressure pM, characterized by the steps de: c) select a specific compression of material k (p) of the injection-cast mass corresponding to the value of pM, d) calculate a real volume Vr taking into account the compression k (p).
