Bonded Neodymium Iron Boron is a composite magnet. It is produced by molding compression of the compound NdFeB alloy powder with epoxy resin, also it can be made by injection or extrusion from NdFeB alloy powder mixed with plastic. The magnetic property of bonded NdFeB magnet is between that of sintered NdFeB and Ferrite, and with good consistency and stability. The magnet shape and dimension are decided by the tooling, like ring, segment, block,etc, without further sintering and mechanical machining processes. After electrodeposited or through other special treatments, it can be used under normal or unfavorable environment conditions for a long time. 
Our company can manufacture magnets in different magnetic properties with dimension ranging from D2.0-D200mm. Mass production and specialized equipment system have guaranteed high efficiency and low cost. Samples with self-made mold can be delivered in 12 days and the strong production capacity can guarantee the shortest delivery period in the industry.
