3.Bonded ndfeb magnet production process:

 

 

 4. Bonded ndfeb magnet applications:

Company products are widely used in hard disk drives, cd-rom drives, DVD spindle motor, stepper motor, dc motor, brushless motor, start the motor, instruments, meters, automobiles, office automation and the various fields of daily life.

 

Bonded NdFeB magnet can be magnetized through inside and outside diameter of multipolar,radial ,various Angle and axial multi-polar. It can be manufactured to all kinds of complex shaped products, superfine, ultra thin, high precision control of disposable. The BH of Bonded NdFeB magnet is three times higher than Sintering heterosexual ferrite magnets , and it also with high HCJ ,high magnetic stability and good consistency.

Performance fluctuations of bonded NdFeB magnet is under 5%,the working temperature can reach 150 ℃. Surface has the gonadorelin coating and the coating epoxy resin, excellent corrosion resistance, the surface is bright and clean and beautiful, no bubble, crack, flake, flash, off wait for a phenomenon.
 

5.Test equipment to ensure the quality  :

1)Permanent magnetic properties measurement instrument-used to test the magnetic parameters of magnetic powder

2)Hall current meter, -used to measure the magnetic powder of fleabane heavy flow velocity

3)Size detection equipment image instrument and universal tool microscope 

4)Micrometer, caliper, dial indicator

5)Density balance and other pressure gauge measuring instruments, the precision balance

6)Waveform tester, is used to test waveform and table, other measurement instruments have tesla meter and disk

7)Fluxmeter for finished product magnetic flux test

 

6.The demagnetization curve of magnetic powder sample 

 

7.About bonded neodymium magnet advantage and disadvantage:

advantages High remanence, high coercive force, high magnetic energy product, high performance ratio, easy processing of all sizes and minimum specifications

disadvantages Corrosion resistance of the surface coating or plating is low
