Abstract
In this study, the effect of sand casting process parameters such as pouring temperature, permeability, sand particle size, mould hardness and moisture on the Axel End Cover (AEC), a product of “Nandratan Foundry & Engineering Works”, was investigated to reduce casting defects. The experimental study was conducted on the AEC as per the L27 orthogonal array of the Taguchi method to determine optimal casting parameters. We performed the Analysis of Variance (ANOVA) to determine the significant effect of the response and the percentage contribution of individual parameters over the response. A confirmation test was carried out to validate the test results. The results revealed that an average (3-months) 4.31 % reduction in the rejection of the AEC with suggested optimum process parameters
