Ndfeb magnets, samarium cobalt magnet, alnico magnets, ferrite magnet production process is also different.Tell from technology, sintered ndfeb magnets and adhesive ndfeb magnets, we mainly speak of sintered ndfeb magnet.
Ingredients to smelting tableting, pulverizing to molding, sintering and tempering magnetic detection to grinding to pin cutting processing, electroplating, magnetization and finished products.Sintering tempering of ingredients is a foundation, is the key ndfeb magnet production tools: a melting furnace, a broken machine, ball mill, jet mill, pressing molding machine, vacuum packaging machine, such as static pressure machine, sintering furnace, vacuum heat treatment furnace, magnetic tester, gauss meter.
