As of neodymium magnets invented in 1982, they were soon referred as the third generation Permanent Magnet, and replace alnico magnets and ferrite magnets in many industrial applications and DIY activities. Just a small pieces of Neodymium Magnet will retained a prodigious of magnetic power. Which will save the dimension and mass of product.
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.
