The temperature fields on the die surface measured by an infrared camera during High Pressure Die Casting process. It is compared to the simulation which has already been adjusted by 8 thermocouples. The directional emissivity of the mold surface is measured in the spectral range [7.5-13µm] between 63-174°C. We obtained an almost uniform emissivity from normal direction to the surface up to 60°. The surface condition is a key point to achieve a reliable temperature field. Similar areas in the temperature fields are identified between experiments and simulation although the measurement conditions are particularly difficult in the foundry environment.
