Die casting is a common industrial process for manufacturing complex-shaped products from light metal alloys. At the end of the casting process, the components must be ejected from the mold by means of ejector pins. In this process, the ejector system influences both production reliability and the quality of the die cast components. Piezoelectric force sensors can be used to determine and investigate the forces acting on the ejector pins or on the component during ejection. These sensors must be preloaded when installed in the die casting system and then calibrated. Since the calibration device and method used so far at the Institute of Joining and Welding is prone to errors and the process is very time-consuming, there is potential for optimization here.
The aim of the work is to design a device and a method for the in-situ calibration of force sensors in the die casting process. The designed device is then to be set up and tested on the die casting system. Depending on the type (bachelor's, student's or master's thesis) or scope of the work, a script for the semi-automated execution of the calibration is also to be prepared.
