Bonded NdFeB magnets
Plastic-bonded NdFeB magnets are especially used in applications where hart ferrite magnets cannot meet magnetic specifications or where sintered rare-earth magnets are not used for economic or production-related reasons. The Bonded NdFeB materials are generally isotropic - i.e. they can be magnetized in any direction with any number of poles

Compression Bonded - this is a technique whereby a special form of NdFeB powder is blended with a plastic carrier material, die pressed and then heated. Parts made in this way can be of complex shapes and come off the tool with close tolerances, requiring no further finish machining. They have lower energy products than sintered materials - in the range of 10 MGOe.

Injection Molded - NdFeB powder is blended with a plastic material and injection molded. The resulting parts have energy products in the 5MGOe range, but can be made with extremely intricate shapes.

Extruded - though not popular at present, NdFeB based flexible magnets can be made by binding NdFeB powder with a carrier material and extruding the material in sheet or strip form. Energy products up to about 6 MGOe have been achieved in this way.
