bonded compression isotropic ndfeb rare earth magnet

Compression NdFeB magnets are made through "compression molding" of the mixture of quick-quenched NdFeB magnetic powder and bonding agent. Due to its high accuracy in size, the bonded magnet may be formed into magnetic components of relatively complicated shape.
Also,it features single-time molding and multi-pole orientation. The injection molded magnet has a high mechanical strength and may be molded together with other matching parts.
Compression bonded magnets offers higher magnetic strength than injection moulded magnets. Bonded NdFeB magnet due to their higher magnetic partical density, but is limited to simple geometric shapes due to the compaction process. The epoxy coating is very resistant to normal industrial alovent and automotive fluids.
The normal applications of these magnets rang from below -40ºC and beyong 165ºC.
Bonded NdFeB magnets widely applied in all kinds of mini-motors, air-conditioner motors, automatic controlling devices, sensors, drivers, telecom and instrument industry.
