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.
