In this paper, a methodology is proposed that makes use of computer-aided heat transfer simulation and experimentally derived factors for injection parameters, to predict wax pattern shrinkages in the investment casting process. The focus is on developing techniques for the early determination of optimum injection parameters to be used for wax pattern production so that resulting shrinkage can translate into an overall improvement in accuracy of the investment casting process.
