    What Are Bonded Magnets Anyway?
    • Bonded magnets are composites of a permanent magnetic powder(s) embedded in a non‐magnetic matrix.
    • The matrix is typically a thermoplastic or elastomeric binder.
    • Common processing techniques are extrusion, injection molding, compression bonding, and calendering.
    • Exhibit excellent mechanical properties compared to fully dense rare earth and ferrite magnets.
    • End product has good finish and dimensional tolerances requiring no finishing operations.
    • Injection molded magnets can be formed into complex shapes and be insert or over molded directly onto other components to produce assemblies.
    • The non‐magnetic binder lowers the density of the magnet and dilutes the contribution of the magnetic powder.
    • They generate less magnetic output per unit volume than fully dense magnets.
    • The two most common magnetic powders are isotropic NdFeB and hard ferrite.

    Advantages of Bonded/Molded Magnet, Ring Compression Bonding Hall Effect Sensor Neodymium Magnet
    • A higher ratio of magnetic material powder to binder gives higher magnetic performance than the injection molded magnets (higher magnetic loading)
    • NdFeB, SmCo, Alnico and Ferrite versions possible
    • Hybrid versions as well (e.g. Ferrite+NdFeB) with combined properties
    • Good tolerances – secondary machining not needed
    • Low electrical conductivity, low eddy currents

    Disadvantages of Bonded/Molded
    • The compression bonding process is limited to simpler shapes such as rectangles, rings, arcs and cylinders. A consistent cross sectional area is required along the pressing direction
    • Possible tooling charges for production and magnetising

    Typical Applications of Bonded/Molded
    • Motors
    • Position sensors
    • Hybrid performance components

    A company wanted a magnet on a joystick to activate Hall Effect sensors to give relative position information. A ferrite magnet would be too weak; a sintered NdFeB neodymium magnet would be too powerful. A compression bonded NdFeB magnet was supplied that had a performance between NdFeB and Ferrite but which had an epoxy finish, good final tolerances and would be low cost in high production quantities. Position Sensor Neodymium Magnet Bonded Ring, miniaturized sensor magnet, compression molded tube magnet, gray epoxy bonded magnet neodymium tube, plastic neodymium power bonded tube magnet, compression bonding neodymium magnet
