At present, China's rare earth NdFeB production has formed an industrial system, and the output has accounted for more than 80% of the world's total output. However, China's production of high-end NdFeB products is lack of competitiveness, which has become a bottleneck restricting the development of magnetic materials industry. The main reason is that the electroplating quality of NdFeB surface in China does not meet the requirements of high-end application fields Restrict its application in high-end products. As we all know, rare earth elements have active chemical properties. It is empty talk to extend the rare earth terminal industry chain without surface coating technology. Therefore, the industry has already reached a consensus of "no electroplating, no high-end".
AISEN MAGNETS uses "Ni Cu semi bright Ni bright Ni" as coating to form a new coating technology on the surface of rare earth magnet, which is used to coat the rare earth NdFeB magnet with "armor".
It is understood that the technology can effectively improve the consistency and stability of rare earth magnet products, and the potential difference between semi bright nickel and bright nickel can make the magnet surface change from longitudinal corrosion to transverse corrosion in the corrosion process, and the service life of the product can be increased by more than 2 times. Ultrasonic cleaning is added in each process of coating, which can effectively remove the impurities on the surface of the coating. The thickness of the coating is reduced from 15 μ m to 10 μ m, which makes the product more delicate and more cohesive.
At present, has two electroplating production lines with the highest level in China, and the crane configuration of the production line draws lessons from the equipment structure of the semiconductor cleaning line, with higher safety and stability. It has the function of automatic control on-line detection, automatic addition of additives in plating bath and automatic pickling. Compared with ordinary electroplating, it can save 80% of labor cost and increase 33.3% of salt spray time of metal surface coating.
AISEN MAGNETS focused on development and manufacturing of Neodymium magnet, has more than 10 years manufacturing experience in producing various sizes, different shape and surface coating. Over 45 different grades of neodymium magnet (strong magnet) widely used in many industry.
