Production process quality monitoring is very important, can by SC chip thickness measurement and detection way JM powder particle size distribution, etc. The high quality product is depends on the production process control, but the customer will be confused, how to determine the performance of the product I bought? The China institute of metrology has developed a variety of models of the permanent magnet magnetic materials technology parameter measuring instrument. Magnetometer (pulse magnetic field PFM) Is a kind of test instruments, high coercive force of permanent magnet shaped magnet is mainly in order to adapt to electric cars and large demand high coercive force of permanent magnet by permanent magnet motor. Production technology of advanced or not directly determine the performance of the magnet quality. Is currently the most advanced technology scales ingot ( SC) Technology, hydrogen broken ( HD) Technology and jet mill ( JM) Technology. Small capacity of vacuum induction furnaces ( 10公斤,25公斤、50公斤) Has been the large capacity ( 100公斤、200公斤、600公斤、800公斤) Vacuum induction furnace. SC( StripCasting) Speed NingZhu chip technology has gradually replace large ingot ( More than 20 - cooling in the direction of thickness 40 mm ingot casting) Hydrogen, broken, HD) Technology and jet mill ( JM) Replaced the jaw crusher, plate mill, ball mill, Wet powder legal system) And ensure the uniformity of the powder, and is advantageous to the liquid phase sintering and grain refinement. Our country is the only country adopts two-step forming technology in the world, the orientation with a small pressure vertical moulding, magnet then using isostatic pressing molding, this is one of the most important characteristics of sintered ndfeb industry in our country. / dongguan magnet products co. , LTD. , magnets, powerful magnets, magnet manufacturers, special-shaped magnet
