    Injection molded NdFeB

    Besides sintered magnets and bonded magnets categories, injection molded magnet is one of the more important developments in magnetic materials, it has opened a new world of application opportunities. Similar to plastic injection molding, magnet injection molding process is by mixing the magnetic powder together with polymer binder, heated in the injection machine and shooting the melted mixtures into the mold to achieve different shapes of products.

    Features and benefits of injection molded NdFeB

    l Injection molded magnets can be of very complex shapes with high precision, typically, tolerance is+/-

    0.005mm, it is suitable for high precision parts

    l It is a new technology to achieve adjustable magnetic properties, composite molding, elasticmagnetization and high mechanical strength

    l By doing insert molding, magnetic material can be directly molded into or onto other assembly components without further assembly process

    l Magnetic powder is neodymium-iron-boron (NdFeB), either isotropic or anisotropic. And Polymerbinders utilized are PA6,PA12 and PPS

    l Anisotropic NdFeB powder achieves the highest magnetic force as injection molded magnet. And it ispossible to achieve BHmax 17GMOe, and can replace some of sintered products
    NdFeB Material Magnetic Properties

    Maximum application temperature is related with magnetic powder and polymer binder. NdFeB material suffers significant irreversible magnetic loss above 120°C, regardless of which binder is used. And on the other hand, the HDT (heat deformation temperature) of the binders is low, when application temperature exceeds the HDT, the binder in injection molded magnet will become soft at some extent, which jeopardizes the product. Maximum application temperatures are listed in above sheet.
