Joining Technology Laboratory
Our offer
Our offer
The eLab offers joining technology systems for the generation of materially bonded joints for electrical contacting and various small part applications.
Together with process experts from the Institute of Welding and Joining Technology at RWTH Aachen University, ISF for short, feasibility studies can be carried out on new products and materials, precision-fit processes developed and sample components or small batches joined. The existing facilities are also suitable for basic development work, such as the identification of influencing factors and robustness tests for specific applications or the setup and calibration of precisely fitting quality monitoring systems for inline process monitoring.
