Computer implemented method for generating a mold model for production predictive control and computer program products thereof

A computer program product tangibly embodied in a non-transitory machine-readable storage medium including code instructions that, when executed by at least one processor of a computer system implements a method for generating a mold model for production predictive control, by performing, once a mold has been inserted in a first injection molding machine, in order to obtain, injected given parts, or molded pieces, the following steps:

• a) receiving
• i. a first group of parameters from a plurality of injection molding machine sensors about performance of a plurality of injection cycles of said first injection molding machine,
• wherein said injection cycles are performed with the first injection molding machine in a set of configurations providing at least different qualities of the injected given parts or different operation points, and
• wherein said parameters of the first group include at least one of Hydraulic Pressure, Screw Position, Screw Speed or Rotational Speed;
• and
• ii. a second group of parameters from a plurality of mold sensors relating to a mold cavity shaped for molding an injected given part in said first injection molding machine, said parameters of the second group at least including pressure and/or temperature evolution of the mold cavity and of the mold along each of the injection cycles in the mold cavity;
• b) classifying each injection cycle of said plurality of injection cycles considering at least the received first and second group of parameters and quality or characteristics of the injected given parts;
• c) processing the received first and second group of parameters by implementing therein one or more algorithms to remove undesired or irregular data values in said parameters;
• d) merging the processed first group of parameters with the processed second group of parameters providing a global group of processed parameters;
• e) executing a machine learning algorithm on the global group of processed parameters generating an extended mold model;
• and
• f) using said generated extended mold model for further monitoring and control of the mold in further injection processes in the first injection molding machine and/or for optimizing a production process of the mold in the first molding machine.
