Abstract

In recent years, computer simulation of investment casting process has begun to complement the experience-based approach in meeting the demands of high quality investment cast parts in a cost effective manner. Results of the simulation of the filling of cast part sample and its solidification process are presented in this paper. The aim of this research was to identify defects during the casting process. A case study has been conducted, involving one of the mechanical parts in a casting industry. The computations are carried out using MAGMAsoft, and the defect was predicted. The findings are compared with the result of similar experiment using Radiographic examination. It shows that there is excellent agreement between computer predicted data and the result from Radiography as the defects occur at the same predicted locations which appears as shrinkage porosity.
