MANUFACTURE AND PROPERTIES OF BONDED NDFEB MAGNETS FROM INJECTION MOLDING

摘要：

The injection molding bonded magnets were prepared by using the MQP-B rapidly quenching NdFeB magnetic powder and polyamide 12.The manufacture technology of bonded NdFeB magnets was described.The effects of content of binder,additives and magnetic powder on the magnetic property,mechanical property and fluidity of injection molding magnets were investigated.Furthermore,the efleet mechanism was revealed microcosmically.The magnetic properties are :Br=0.539T,Hcb=345.37kA/m,Hci=681.02kA/m,and (BH)max= 47.37kJ/m3.
