Raw Material
The main raw materials of NdFeB magnets are: rare earth metal neodymium, rare earth metal praseodymium, pure iron, aluminum, boroferric alloy and other rare earth raw materials.
NdFeB magnet processing tools
There are special slicers, wire cutting machine tools, flat grinders, double-sided machines, punching machines, chamfering machines, and electroplating equipment.
Process
The manufacturing process of NdFeB magnets, samarium cobalt magnets, Alnico magnets, and ferrite magnets is also different. From the process point of view, there are sintered NdFeB magnets and bonded NdFeB magnets, and we mainly talk about sintered NdFeB magnets.
Ingredients → Smelting ingots→ milling → pressing → Sintering and tempering → Magnetic detection → grinding → Pin cutting processing → electroplating → magnetizing → finished products. Among them, ingredients are the foundation, sintering and tempering is the key NdFeB magnet production tools: there are melting furnace, jaw crushing machine, ball mill, air mill, pressing molding machine, vacuum encapsulation machine, isostatic press, sintering furnace, heat treatment vacuum furnace, magnetic performance tester, Gaussian meter.
