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, elastic magnetization
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 Polymer binders
utilized are PA6,PA12 and PPS
l 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

Applications

(Super) Compact Motor, Actuator, Compact Sensor, Motor, etc



* 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.
