  • SFB 653 – L3 – Reading and Writing of Magnetically-Saved Data
    Within the framework of the Sonderforschungsbereich (SFB) 653 “Gentelligente Components in a Life Cycle” in the subproject, L3, a method for magnetic storage of data directly on the surface of magnetic components in an industrial production environment is researched at the IMPT. With this concept, the data is stored magnetically with an inductive, magnetic write head. For the readout of data, a method that is based on the magneto-optic Kerr effect is used.

  • Tool-integrated temperature measurement for press hardening
    As part of the research project, a tactile thermoresistive temperature sensor based on thin-film technology was developed for use in hot forming. By selecting a suitable base material and designing a sensor contact outside the mechanically stressed area, a negative influence on the component properties could be eliminated. To achieve an economical service life, the sensor surface was provided with a wear protection layer. In addition to the realization of a full control within the scope of quality assurance, the sensors can also contribute to a more economical design of the production process.
