Universal Model for the Quality Analysis of Aluminium Alloys Castings

: The production of products in foundry technology is fraught with many problems, including the impossibility of controlling all parameters affecting casting quality. It is important to take effective improvement measures related to the implication of non-destructive testing (NDT), but these methods are rarely combined in the diagnostic cycle. As part of quality assurance, it is also important to identify the root causes of problems. In view of this, it is appropriate to develop a model that facilitates diagnosis and the search for the key causes of nonconformity, which would be a combination of NDT and quality management methods. The originality of the model presented in the study is reflected in the combination of NDT and quality management methods. The model presents a universal method that can be implemented in foundries to ensure the stability of production processes. The application of the model brings tangible benefits in the form of an increase in the speed of detection and a reduction in non-conformities in aluminium castings, which significantly increases the quality level of the products offered. Further research directions will address the application of the model within foundry processes characterised by loss of quality stability.
