Manufacture and application of a sensor inlet for high-temperature measurements in the frictional zone of an extrusion die

High operating temperatures are omnipresent in the production engineering environment. In order to achieve optimum production results, measurements of the temperature are carried out in most production processes. In this research, an integration concept, a temperature field simulation for positioning and a process chain for the production of a sensor insert in the forming zone of an extrusion die was developed. Subsequently, the application behavior and the applicability in the process were evaluated. It was shown that the insert could withstand the forces during extrusion and had no effect on the end product. In addition, a friction-induced temperature increases of 110 °C was observed during the extrusion process. There is a good agreement between the simulative prediction and the experimental results.
