Bonded NdFeB Permanent Magnets
 

  • Composition of NdFeB magnet powders are embedded in thermoplastic and formed on injecton moulding machine.
  • Possible incorporation of shafts or other insert to the magnet during manufacturing process
  • Varieties of shapes, gears, thin ring and many other complicated forms
  • Good resistance to corrosion and chips
  • Partly and fully magnetizable of magnets
