Abstract

Due to the inappropriate selection of processing parameters

defects such as shrinkage porosity

cracks and deformation often occurs in investment casting thin-walled and complex parts

decreasing the casting production rate. Aiming at features of amounts of processing parameters to be dealt with in investment casting and their interaction

the FEM （finite element method） was used to simulate filling process to understand effects of different parameters on filling process and to predict potential defects and then to optimize design. The temperature field and stress field in solidification in vestment casting shredding mills was simulated by the ProCAST to observe the effects of filling velocity on quality.
