Bonded NdFeB magnets are produced by molding NdFeB powder with a polymer binder, supporting injection and compression molding directly into complex, net-shape parts — including thin-walled rings and multi-pole geometries impossible to machine from sintered material.
Parts come out of the tool at final dimensions with excellent consistency, which makes bonded NdFeB ideal for high-volume automated assembly of micro motors, sensors and encoders.
Multi-pole magnetization in the tool eliminates a separate magnetizing step and enables precise pole patterns for rotary encoders and BLDC rotors.
