Improving the Surface Condition of the Casting of the Control Panel Cover

The purpose of the study was to develop a method for identifying and analyzing defects in aluminum castings.A correlation was made between visual examination, leakage, Ishikawa diagram, FMEA method, Pareto Lorenz diagram and the 5WHY method? in quality control.The sequential deployment of methods provides a multifaceted set of information.Integration of non-destructive testing (NDT) is found in the literature, but test results are not analyzed using quality management techniques.The integration of the indicated methods is an aspect of the model's novelty.A key issue in improvement activities is the identification of the cause of loss of quality stability.It demonstrates the need for models for diagnosing and analyzing nonconformities and the relevance of the subject matter undertaken.A test of the model in a foundry company was carried out, thanks to which the cause of the decrease in the level of quality was identified -in the studied period the percentage of nonconforming castings was 1.67% -4.52%.The problem was the pouring of an alloy with the wrong temperature into the mold.The implication of the model made it possible to eliminate nonconformities.
