Product Description

Neodymium magnet is refer to neodymium iron boron magnets or ndfeb magnets. Neodymium magnets is a kind of rare earth magnets with enormous magnetic power. As of today, neodymium magnets have applied in modern consumer electronic products like smart phones,computers,camera lens and more.The neodymium magnets also used in generators,speakers, telephones, computers,cars, DC motors, odometers and sensors...

Main Manufacturing process of ndfeb magnets 

1.Pressing ndfeb garins: pressing process was operated in strong magnetic environment.

2.Sintering of ndfeb blocks: sintering was processed in a vacuum furnace.

3.Wire cutting: ndfeb magnets are fragile materials operated in wire cut machines for the

tailored irregular shapes.

4.Grinding process: Grinding process: To reach the tolerance of magnets.

5.Plating: Neodymium magnets had been treated with different platings to prevent rust. 

The popular platings for neodymium magnets are epoxy, nickel, NICUNI ,zinc and even 

silver plating and gold plating.

6.Magnetization: the procedure are processed with magnetization machine with magnetic 

feild ranged from 2~100 koe.
