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
lInjection molded magnets can be of very complex shapes with high precision, typically, tolerance is+/-
0.005mm, it is suitable for high precision parts
lIt is a new technology to achieve adjustable magnetic properties, composite molding, elastic magnetization
and high mechanical strength
lBy doing insert molding, magnetic material can be directly molded into or onto other assembly
components without further assembly process
lMagnetic powder is neodymium-iron-boron (NdFeB), either isotropic or anisotropic. And Polymer binders
utilized are PA6,PA12 and PPS
lAnisotropic 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
