Smart Molding International 2-2023

46 smart_molding international 2/2023 measuring technology Preventive quality assurance Operating ComoNeoPREDICT in combination with the STASA QC software also reduces the effort required during process analysis and development. To find a stable process window on a qualified machine in the final phase of process development, coordinated DoEs need to be created and executed. The purpose of the DoE with varying machine parameters is to achieve variance of the process conditions represented by the cavity pressure so as to cover the process window. Mathemat i ca l correl at i on of the measurement values with the continuous, attributive quality characteristics that are measured afterwards supplies a model for ongoing prediction of the quality of each part produced. The model attains a very high degree of accuracy thanks to special algorithms and the use of machine learning in the STASA QC software. This makes it possible to predict part quality during production, and also to separate parts that are out of tolerance. In practice, this function is performed on a fully automated basis by the ComoNeo process monitoring system and the embedded function of ComoNeoPREDICT. The benefits: the required quality can be guaranteed, and testing costs can be drastically reduced – giving injection molders ideal conditions to safeguard their competitive edge.
