An iterative method for controlling a production process and a production control unit for iteratively controlling the production process of at least one of a material and a product formed out of the compound material. Nominal parameters and indicative parameters selected from the group comprising process parameters, material recipe parameters and product property parameters are provided in the iterative method or to the production control unit. The iterative method and production control unit consider the nominal and indicative parameters, including both process parameters and material recipe parameters to determine whether a setting of at least one correcting parameter for a subsequent process is necessary. A correcting parameter is selected from the group comprising process parameters and recipe parameters and the setting of at least one correction parameter comprises the choice of a parameter from a parameter set comprising process parameters and material recipe parameters.

Iterative method and production control unit for controlling production process

A forming process of plastic parts is simulated. The position and time of plastics particles which exceed at least one defined critical limit are detected. The final positions of particles in the surface layer of the plastics part are computed. The positions of the particles in the surface layer are defined as positions with deviations in the surface appearance.
