The temperature distribution is very important for the validation of models for the simulative part design due to the high influence on the moulded part, but is also very challenging to measure. Nowadays temperature measurements at the transition of the polymer melt to the mould or near the surface of the polymer melt are applicable and do not allow either a non-invasive analysis or a determination of the temperature field. In the approach of ultrasound tomography an ultrasound beam is emitted into the melt and the time-of-flight (TOF) is detected by a set of transducers, which are mounted around the melt. Subsequently the measurement is repeated from different directions. Using algebraic reconstruction techniques, a distribution of the ultrasound velocity can be calculated based on the TOF-dataset. With additional information about the polymer from pvT-behaviour, the distribution of the ultrasound velocity can be converted into a temperature field. To evaluate the applicability of ultrasound tomography an injection compression mould with a cylindrical-shaped cavity is currently designed, which fulfills the requirements for ultrasound tomography. Twenty ultrasound transducers are radially arranged around the cavity to reach a spatial resolution of 3.5 mm² per area element. The transducers are connected to buffer rods that provide a temperature shield for the ultrasound transducers and enable the possibility to scatter the ultrasound beam for fast signal detection. Filling simulations with Autodesk Moldflow 2015 were done to determine the temperature distribution in the mould at different time steps and are used to test the reconstruction algorithms. The results show a good agreement to the simulated temperatures. For accurate temperature measurements with ultrasound under real injection moulding conditions further research must be done, with respect to the influence of process parameters, e.g. cooling rate, and the behaviour of ultrasound in solidified polymer melts
