Computer-implemented method for optimizing an injection-molding process for producing thick-walled components

摘要

A computer-implemented method for optimising an injection moulding process for producing thick-walled components based on a model parameterised on the basis of parameters to be predetermined is provided, wherein a component to be produced is represented in the model with a component geometry, and the method comprises at least the following steps: e) defining a group of parameters as primary characteristics on the basis of a relative influence of the parameters on a predetermined model response, and f) defining parameter values for the primary characteristics as starting values for a subsequent optimisation of the model and of respective tolerance ranges for the primary characteristics, c) optimising the parameter values of the individual primary characteristics with respect to a desired value of the model response in the respective tolerance ranges, proceeding from the starting values from step a), and d) setting the optimised parameter values from step c) as the corresponding starting parameter values on an injection-moulding machine.

1. A computer-implemented method for optimising a multi-layer injection moulding process for producing thick-walled components based on a model to be parameterised on the basis of parameters to be predetermined, wherein a component to be produced is represented in the model with a component geometry, the method comprising:
a) for each of the individual parameters, determining a value for a predetermined model response for various parameter values of the respective parameter and a resulting relative influence of the individual parameters on the value for the model response, b) defining a group of parameters as primary characteristics on the basis of the relative influence of the individual parameters on the predetermined model response determined in step a), c) determining a correlation of the primary characteristics in relation to the value for the model response for various parameter values of the individual primary characteristics, d) defining parameter values for the primary characteristics as starting values for subsequent optimising of the model and respective tolerance ranges for the primary characteristics on the basis of the correlation determined in step c), e) optimising the parameter values of the individual primary characteristics in terms of a target value of the model response in the respective tolerance ranges proceeding from the starting values from step d), and f) setting the optimised parameter values from step e) as corresponding starting parameter values on an injection-moulding machine.
