ABSTRACT
Shrinkage cavity may be detrimental to mechanical performances of casting parts. As a consequence, design engineers often use overly large safety factors in many designs due to insufficient understanding of quantitative effects of shrinkage cavity defects. Now a day casting simulation has become a powerful tool to understand mould filling, solidification and cooling to predict the location of internal defects such as shrinkage porosity, sand inclusions and cold shuts. It can be used for developing new casting without shop-floor trials. This paper describes the benefits of casting simulation and how to reduce shrinkage defect in casting part with Simulation process and theoretical background.
