| Bonded NdFeB magnets, are composed of a |
| special form of NdFeB powder with a plastic carrier |
| material. They have lower energy product than |
| Sintered NdFeB magnets. Very complicate shapes |
|
can be produced in Bonded NdFeB magnets with |
| very close dimensions. |
|
Manufacturing Process |
|
Bonded NdFeB magnets is produced by a special |
| form of NdFeB powder 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. |
|
Machining |
| Bonded NdFeB magnets is easily machined. |
| Coolants must be used while machining this material |
| in order to avoid spontaneous combustion of |
| powder. Machining this material removes a layer of |
| protective coating, and re-coating for corrosion |
| resistance may be necessary. |
|
Surface treatments |
|
The corrosion resistance of Bonded NdFeB magnets |
| is considered poor, epoxy coating is mostly common |
| used for bonded NdFeB magnets. |
|
Magnetizing |
| Bonded NdFeB materials are isotropic and can be |
| magnetized in any direction or with multiple |
| poles. Special magnetizing fixtures are required in |
| order to achieve multiple pole magnetization, |
| depending on complexity of design and production |
| rate requirements. |
