NdFeB magnet manufacturing process

raw material

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

NdFeB magnet processing tools

There are special slicers, wire cutting machines, flat grinders, double-sided machines, punching machines, chamfering machines, and electroplating equipment.

Process flow

The manufacturing process of neodymium iron boron magnets, samarium cobalt magnets, alnico magnets, and ferrite magnets are also different. In terms of technology, there are sintered NdFeB magnets and bonded NdFeB magnets. We mainly talk about sintered NdFeB magnets.

Ingredients → smelting ingot → pulverizing → pressing → sintering and tempering → magnetic inspection → grinding process → pin cutting process → electroplating → magnetization → finished product. Among them, the ingredients are the basis, and the sintering and tempering is the key NdFeB magnet production tools: smelting furnace, jaw crusher, ball mill, jet mill, press forming machine, vacuum packaging machine, isostatic press, sintering furnace, heat treatment vacuum furnace, Magnetic performance tester, Gauss meter.
