This paper describes the modeling verification of the thermal history of the sand casting process. A simulation model of a two-ingate mould and a three-ingate mould of sand casting are developed. The theory behind the model is based on the network analysis method where a FORTRAN program, namely Thermal Network Analyzer, is used to calculate the numerical output. The analysis was done by concentrating on chosen nodes as references. The change of temperature in the casting and sand with time was monitored. Generally, the simulation results showed that every point in the mould was cooling. The heat was transferred from the casting to the sand and from the sand to the surroundings. The predicted results were then compared with experimental data, the agreement between them being reported.
