Abrégé

The invention relates to a method for regulating and/or controlling functions of an injection moulding machine in which a melt (3) is introduced into at least one cavity (1.3 - 1.7, 7), said melt being associated with the at least one pressure sensor (4.3 - 4.7) that comes into direct contact with the melt or can react at least on a melt front. The invention is characterised in that the moment in which the pressure sensor (4.3 - 4.7) recognises the melt or the melt front, is the moment the pressure sensor is used as a switching point for the regulation or control process.
