In a process for manufacturing injection mouldings in an injection moulding machine for processing plasticized masses, a regulated subsequent pressure is applied by the injection moulding unit (13). At least in the areas of the moulding away from the sprue, the subsequent pressure is generated by a regulated volume alteration of the mould cavity. The subsequent pressure can thus be reliably distributed during the subsequent pressure phase even in the case of complex mouldings.
Selon ce procédé de fabrication de pièces moulées par injection dans une machine de moulage par injection qui façonne des masses plastifiables, l'unité de moulage par injection (13) applique une pression ultérieure réglée. Au moins dans les zones de la pièce moulée par injection éloignées du culot d'injection, la pression ultérieure est générée par une modification réglée du volume de la cavité du moule. On peut ainsi distribuer de manière fiable la pression ultérieure pendant la phase d'application d'une pression ultérieure, même dans le cas de pièces complexes.
