Polymer Bonded Magnets Selection Guideline

    If you want to take advantage of the tremendous opportunities that polymer bonded magnets offer in terms of shape-forming capabilities, reduced assembly costs, flexibility in magnetic orientation, a wide range of magnetic performance, and suitability for use in different operating conditions, then you can choose from the following bonded magnet options:

    When the highest level of magnetic flux density is needed from a bonded magnet and when you can make use of simple shapes like rings, discs or cylinders, then Compression Molded NdFeB is preferred.
    When complex shaping capabilities are more important, or when there are opportunities to reduce assembly costs using insert or overmolding techniques, then Injection Molded NdFeB is the best choice.
    In cases where the advantages of an injection molded solution are desired, but cost is more important than magnetic performance (i.e. size and weight considerations are not critical), then Injection Molded Ferrite should be considered.
    If only slightly better magnetic performance is needed compared to what is attainable using ferrite alone, and cost is still a major limitation, then Hybrid Injection Molded Ferrite/NdFeB magnets may be the right solution.
