Defect analysis of EN AC-435000 alloy die castings using the Pareto-Lorentz diagram

Purpose: The purpose of this research is to describe the most important defects in die castings made of EN AC-435000 alloy and to present preventive measures and to rank these defects using Pareto-Lorenz analysis. Design/methodology/approach: The paper provides a comprehensive look at the causes of defects in finished products. During the analysis, Ishikawa and Pareto-Loretnz diagrams were used to get information on what are the main defects in finished products and what steps should be taken to optimize the production process. Findings: An research was used a typical material applied in the aerospace and automotive industries. The article shows that even small deviations from the accepted technological assumptions, in this case temperature, leading to products that deviate from the accepted quality assumptions. Practical implications: The article is intended not only for the scientific community, including students, but also for technologists working in industry. It shows the process of identifying the locations and types of damage to finished products and what steps should be taken to avoid them in the future. Originality/value: Demonstration, difficulties in optimizing the die casting process for EN AC-435000 alloy.
