Method of determining a number of process parameter values within an injection mould during an injection moulding process, which method comprises the steps of - determining geometric data of the injection mould and/or of a form part (1, 1', 1") to be manufactured in the injection mould, - determining a virtual part-specific pressure curve (ps) of an injection moulding process on the basis of the geometric data, - determining a part-specific event pattern (Ms) on the basis of the virtual part-specific pressure curve (ps), whereby the part-specific event pattern (Ms) comprises a plurality of unique virtual events (E S1, E S2, E S3,...) linked to characteristic event locations (F 1, F 2, F 3,...) of the part geometry, to each of which is assigned at least one relative time information (t S1, t S2, t S3,...) and/or virtual actuator position as well as at least one position datum, which defines a position of a melt front of the injection moulding material in the injection mould, - carrying out an injection moulding process using the injection mould and determining a measured pressure curve (p m) during the injection moulding process, - determining a measurement event pattern (M m) on the basis of the measured pressure curve (p m), wherein the measured pressure curve (p m) comprises a plurality of unique measurement events (E m1, E m2, E m3,...), to each of which is assigned at least one time information (t m1, t m2, t m3,...) and/or actuator position, - assigning virtual events (E S1, E S2, E S3,...) of the part-specific event pattern (M S) to measurement events (E m1, E m2, E m3,...) of the measurement event pattern (Mm), - deriving process parameter values on the basis of the position data assigned to the virtual events (E S1, E S2, E S3,...) and on the basis of the time information (t m1, t m2, t m3,...) and/or actuator positions assigned to the measurement events (E m1, E m2, E m3,...) that were matched to these virtual events (E S1, E S2, E S3,...). - determining geometric data of the injection mould and/or of a form part (1, 1', 1") to be manufactured in the injection mould, - determining a virtual part-specific pressure curve (ps) of an injection moulding process on the basis of the geometric data, - determining a part-specific event pattern (Ms) on the basis of the virtual part-specific pressure curve (ps), whereby the part-specific event pattern (Ms) comprises a plurality of unique virtual events (E S1, E S2, E S3,...) linked to characteristic event locations (F 1, F 2, F 3,...) of the part geometry, to each of which is assigned at least one relative time information (t S1, t S2, t S3,...) and/or virtual actuator position as well as at least one position datum, which defines a position of a melt front of the injection moulding material in the injection mould, - carrying out an injection moulding process using the injection mould and determining a measured pressure curve (p m) during the injection moulding process, - determining a measurement event pattern (M m) on the basis of the measured pressure curve (p m), wherein the measured pressure curve (p m) comprises a plurality of unique measurement events (E m1, E m2, E m3,...), to each of which is assigned at least one time information (t m1, t m2, t m3,...) and/or actuator position, - assigning virtual events (E S1, E S2, E S3,...) of the part-specific event pattern (M S) to measurement events (E m1, E m2, E m3,...) of the measurement event pattern (Mm), - deriving process parameter values on the basis of the position data assigned to the virtual events (E S1, E S2, E S3,...) and on the basis of the time information (t m1, t m2, t m3,...) and/or actuator positions assigned to the measurement events (E m1, E m2, E m3,...) that were matched to these virtual events (E S1, E S2, E S3,...).
