Abstract: The invention describes a method of determining and visualizing process parameter values of an injection moulding process, which method comprises the steps of determining geometric data of the injection mould (1F) and/or of a form part (1, 1?, 1?) to be manufactured in the injection mould (1F), carrying out an injection moulding process using the injection mould (1F) and recording measurement values as a function of the injection time and/or an actuator position (s), determining, as process parameter values on the basis of the measurement values and geometry data of the injection mould (1F), a flow front position inside the injection mould (1F) or the form part (1?, 1?) as a function of the injection time and/or an actuator position. The invention further describes a corresponding process parameter value determining apparatus (20) and an injection mould arrangement (10) with such a process parameter value determining arrangement (20).

Abstract: The invention describes a method of determining a number of process parameter values within an injection mould (1F) during an injection moulding process, which method comprises the steps of determining geometric data of the injection mould (1F) and/or of a form part (1, 1?, 1?) to be manufactured, determining a virtual part-specific pressure curve (pS) of an injection moulding process, determining a part-specific event pattern (MS) on the basis of the virtual part-specific pressure curve (pS), carrying out an injection moulding process using the injection mould (1F) and determining a measured pressure curve (pm) during the injection moulding process and determining a measurement event pattern (Mm) on the basis of the measured pressure curve (pm). Process parameter values are derived on the basis of the virtual event pattern and the measurement event pattern. The invention further describes a corresponding process parameter value determining apparatus and an injection mould arrangement.
