Investment casting process parameter selection by Weighted Sum Method

Abstract

Investment casting a known mechanical process relied on lost wax casting, the most known metal-framing strategies. The expression "lost-wax casting" can likewise allude to present day investment casting processes. The Investment casting have been used in different structures throughout previous 5,000 years. This was trailed by hundreds of years of utilization of gems and artistic items previously the approach of the Second World War used for the advancement of aviation and hence engineering segments. In this paper we have tried to optimise the parameters of investment casting using weight sum model method using input parameters as injection time, injection pressure and injection temperature. In order to optimise surface finish and shrinkage in process of mould making as it is crucial part of the whole manufacturing process to get perfect cast.
