The process of making magnets

Raw material

The main raw materials of NdFeb magnets are: rare earth neodymium metal, rare earth praseodymium metal, pure iron, aluminum, ferroboron alloy and other rare earth raw materials

Ndfeb magnet machining tool

There are slicing machine, wire cutting machine, grinding machine, double-sided machine, punching machine, chamfering machine, electroplating equipment.

Process flow

Ndfeb magnet, samarium cobalt magnet, aluminum nickel cobalt magnet, ferrite magnet production process is also different. From the process, there are sintered ndFeb magnets and bonded NdFeb magnets, we mainly talk about sintered NdFeb magnets.

Batching → smelting to make ingot → powder making → molding → sintering tempering → magnetic testing → grinding processing → pin cutting processing → electroplating → magnetization → finished product. Among them, batching is the foundation, sintering tempering is the key NdFeb magnet production tools: melting furnace, jaw breaking machine, ball mill, air mill, pressing machine, vacuum sealing machine, isostatic press, sintering furnace, heat treatment vacuum furnace, magnetic tester, Gauss meter.
