Six Sigma (DMAIC) Approach to Optimise Operation Variables in High Pressure Die Casting

Suraj R. Marathe, Carmo E. Quadros

Abstract


Components manufactured by High Pressure Die Casting (HPDC) typically have excellent mechanical and metallurgical properties, and the process generally preferred for the manufacture of high-value-added products. This research paper focuses on the implementation of the Six Sigma philosophy to optimize the variables of the HPDC manufacturing process. As a systematic outline for quality improvement and achievement business excellence, the Six Sigma philosophy has become the model of the industrial world in recent years. The proposed work tries to simplify the phases of Six Sigma and categorizes the given tools/techniques for their utility. The work further validates its effectiveness by conducting a successful case study in an HPDC process. The five phases DMAIC (Define, Measurement, Analyse, Improve, and Control) use the following qualitative and quantitative tools. Examination of various critical process parameters and the interactions among them carried out with the help of Taguchi’s method of experimental design.
