Popis: The present study was numerically and experimentally investigated on thermal deformation of AC7A and AC4C aluminum alloy used as a casting material for manufacturing automobile tire mold. In this study, temperature distributions of AC7A and AC4C casting material were numerically calculated by finite element analysis (FEA). In order to compare and verify results calculated by numerical analysis, the experiment was carried out on the same condition of numerical analysis. The temperature distribution numerical analysis result revealed that the cooling patterns were predicted almost similar results during cooling process of two casting material. Also, the thermal deformation was calculated from the temperature distribution results. The thermal deformation was closely related to the temperature difference between the surface and inside of the casting.
