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 (SF) of the injection moulding material (KS) 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 (SF) of the injection moulding material (KS) 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 ,...). <EOS>
