Abstract

Casting process is the most widely used process in manufacturing industries especially in automobile products. Foundry industry suffers from the poor quality and productivity due the large number of process parameter. Since the quality of casting parts is mostly influenced by process condition, how to determine the optimum process condition becomes the key to improving part quality. Improvement in casting quality is the process of finding the root cause of occurrence of defects such as sand drop, blow hole and shrinkage in the rejection of casting and taking necessary steps to reduce the defects. Good quality of casting can be achieved by optimization of controllable process parameters such as compatibility, permeability and green compression strength. The effects of these parameters on casting defects and subsequent setting of parameters with the levels have been accomplished by Taguchi’s parameter design approach. Taguchi based L9 orthogonal array have been used for the experimentation and result has been carried out using Minitab 14 software for analysis of variance. The selected process parameters and verification experiment has been performed for finding the optimal value.
