Neodymium-Iron-Boron magnets used three types of production technology
Jan 16, 2017

Found that many people interested in ND-Fe-b production, some projects we also asked about this matter, free today just to give us about three neodymium-Iron-Boron magnets used in the production process.

One of neodymium-Iron-Boron magnets are permanent magnets, it has a very high coercive force HC, maximum energy product and the remanence br, magnetic stability is very good, than the magnet much lighter in weight, so its range of application is very wide, almost all walks of life.

Neodymium-iron-boron in daily production rates from 100 to hundreds of per cent, depending on the process differ. Neodymium-Iron-Boron magnets used in daily production of three production processes, sintering, bonding technology and plastic injection molding process, here we take a look at these technology content.

Process is a magnetic material sintered ND-Fe-b magnets produced by Jet mill powder, and then placed in a smelting furnace into overall material specifications, this process produced very high coercivity of neodymium-Iron-Boron magnets, and has more than 10 times more than normal ferrite magnetic energy product. This kind of technology, the price of neodymium-Iron-Boron relative to certain standards, not differ too much. After the production, based on the need to cut to the shape of the product, but the surface of chemical activity is relatively high, so must surface plating handle, commonly used are zinc nickel plating.

Bonded ND-Fe-b magnet technology and sintering process than product price of neodymium-Iron-Boron is higher, mainly because it is one, once the operation is complete, no further additional cutting operations, it is by neodymium-Iron-Boron powder and other materials mixed together, through compression, extrusion or injection molding technology magnet.

Injection molded NdFeB magnet technology is the highest of all process requirements, the technology to produce the highest price of neodymium-iron-boron, it requires extremely fine, precision molds, neodymium-Iron-Boron powder inside complex finished products, these products are very thin.
