    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

    -Injection molded magnets can be of very complex shapes with high precision, typically, tolerance is+/-
    0.005mm, it is suitable for high precision parts
    -It is a new technology to achieve adjustable magnetic properties, composite molding, elastic magnetization and high mechanical strength
    -By doing insert molding, magnetic material can be directly molded into or onto other assembly components without further assembly process
    -Magnetic powder is neodymium-iron-boron (NdFeB), either isotropic or anisotropic. And Polymer binders utilized are PA6,PA12 and PPS
    -Anisotropic NdFeB powder achieves the highest magnetic force as injection molded magnet. And it is possible to achieve BHmax 17GMOe, and can replace some of sintered products. Injection Bonded Neodymium Magnet, plastic neodymium injection molded magnets

    Due to the increased and unstable prices for Rare Earth elements there are activities to develop alternative hard magnetic materials. Reducing the amount of material necessary to produce complex sintered NdFeB magnets can also help to reduce some of the supply problem. Metal Injection Molding (MIM) is able to produce near net shape parts and can reduce the amount of finishing to achieve final geometry. Although MIM of NdFeB has been patented and published fairly soon after the development of the NdFeB magnets there has never been an industrial production. This could be due to the fact that MIM was very young at that time and hardly developed. Thus, the feasibility of the process needs to be revaluated. This paper presents results of our work on determining the process parameters influencing the magnetic properties of the sintered magnets as well as the shrinkage during processing. The role of binder and powder loading on the alignment of the particles as well as on the carbon and oxygen contamination was examined.
