    “Field systems for magnetsising”

    Our company has developed a field system that is suitable for various applications, for example to magnetise permanent magnets made of plastic-bonded hard ferrite or AlNiCo; for calibrating measuring devices, etc.

    Further detailed information can be found in our Manet Technology Compact 02/2024 “Field system for magnetising“.

    “Chip trap magnets in transmissions”

    For decades, chip trap magnets have been used successfully in oil pans or on oil drain plugs in cars. With our polymer-bonded permanent magnets, however, a higher catching effect is possible despite weaker fields due to the material. At the same time, the polymer-bonded hard ferrite magnets offer an economical and more cost-effective solution.

    “Robust angle measurement with an in shaft-solution”

    For many years now, we have been publishing articles on topics worth knowing about and current technologies relating to the use of permanent magnets and permanent magnet systems in industrial applications.

    The increasing importance of electricity as an energy source in industry has spurred us on to develop a solution with magnets that are robust against electrical interference fields.

    Christmas donation

    As in the past years Magnetfabrik Bonn has decided to support the DKMS, the German bone marrow donor center. Instead of sending out Christmas cards and gifts to our business partners, we have donated 5.000 € to help fight leukemia. The DKMS is a non-profit organization we feel connected to, as a lot of our employees are registered as potential donors and some have even donated stem cells already.

    We wish you and your loved ones merry Christmas and all the best for 2018.

    Our reply to the resource issues rare earth: Sensor magnets on material basis hard ferrite in plastic bonding

    Our reply to the resource issues rare earth: Sensor magnets on material basis hard ferrite in plastic bonding

    The encoder magnets introduced here are the result of the further development of our series of plastic-bound magnets for angular sensors. Our objective was to provide a more economical solution compared with magnets on the material basis of rare earth metals, to achieve a greater independence from raw material sources in Asia and to realise shaping and magnetising in a single production process.

    We have developed an rotary encoder magnet on a hard ferrite material basis. It is produced in an injection moulding process and magnetised directly in the too. This reduces material and production costs a well as part-specific tool costs.

    Summary of technical advantages of encoder magnets made of plastic-bound hard ferrite and plastic-bound NdFeB in comparison.

    Advantages of magnets based on hard ferrite: better contour accuracy due to smaller granulation of magnetic filler,
    corrosion stability, no irreversible magnetic loss at high temperatures up to 150°C and single level safe manufacturing process.

    Advantages of solutions on rare-earth basis (NdFeB): greater field strength, measuring distance at comparable diameter approx. 1-2 mm large, less possibility of external manipulation (greater coercive field) and smaller reversible temperature drift (approx. 13% per 100K instead of 20% per 100K), however, this also causes irreversible losses!

    Summary: We are introducing a new magnet concept for a magnet for angular sensors for front-face retrieval. We can offer approx. 30% cost reduction for large serial production; the part-specific tool costs are generally also more economical.
