Our Bonded Magnet is unmatched in quality. It is a Rare-earth Neodymium Magnet developed from quenched NdFeB powder and binders by following injection moulding or compaction moulding process. This type of magnet is reckoned high tolerance and outstanding mechanical properties, due to which, it can be carved into complex shapes, moulding either one time or with a multi-polar orientation. It is very easy to inject different types of material into Bonded Magnet and increase its efficiency. Magnetic rings made from bonded magnets are suitable to be used in hard drives of computer, mobile phones, air conditioners, refrigerators, micro-motors, and so forth.
Features:
- Excellent magnetic properties
- Can be carved into various complex shapes owing to good mechanical property
- Tough and can be used driving shaft or other plug-ins
- Stable in moderate temperature
- Radial-oriented multi pole magnetic ring
Application:
- Computers (optical drives, hard drives, and floppy disk drive spindle motor)
- Printers
- Home appliances (air conditioners, refrigerators)
- Micro-motors
- Mobile phones
