Abstract

The present study shows the benefit of using casting simulation software in investment casting to analyze different defects like shrinkage porosity, cold shut, blowholes, and hard zones. In this context, three industrial case studies are discussed. For the first case, 100NB flange is taken as component and simulation is done by considering different types of in-gates to study the effect of shape of in-gate on different casting defects. In the second case, effect of pouring temperature on shrinkage size is examined by considering flange as component and proper methoding is done with the help of simulation software. In third case study, pistol body is taken as component and effect of pouring temperature and need of proper methoding on different casting defects are examined. All the simulation results are validated with shop-floor trial results.
