Among the selected process parameters, the degassing frequency is noted as greatest influencing factor up to 47% on response, next influencing factor as metal temperature with 45% contribution on response. The regression model, surface and contour plots are developed to identify the most contributing process parameter. By using the Minitab soft tool, response surface methodology is carried out. Response graphs are plotted to determine the preferred level for each parameter.

Analysis of variance table is generated to determine the statistical significance of the parameters. Each factor is considered with three levels and Taguchi technique is employed. In this study, some of the factors that have reasonable influence on blow holes defect are identified. The primary intent of this paper is to enhance the quality of aluminium die casting products using optimisation techniques such as Taguchi and response surface methodology. However, the casting process industries suffer from poor quality of castings due to involvement of large number of process parameters.
