| Bonded NdFeB Magnet |
 |
Bonded neodymium is produced by neodymium powder and plastic powder with pressing or plastic injection.
With this workmanship, the product can reach high precision without furthering machining.
Normally coated with black or grey epoxy
Can make axial magnetization (or with multiple poles), and radial magnetization (or with multiple poles).
Mainly used CD ROM, DVD main shaft engine, stepping motor, non-brush motor. Servo motor and buzz speaker etc.
