CDYH Magnet Technology Group was established in July 1993 and was listed on the Shenzhen Stock Exchange in October 2010.
The company is the world's largest manufacturer of bonded NdFeB magnets. The company's main research and development, production and sales of products include bonded neodymium iron boron magnets, hot-pressed neodymium iron boron magnets, samarium cobalt magnets, injection magnets, and various magnet components. The products are mainly exported to developed countries or regions such as Japan, Europe, the United States, South Korea, Taiwan, etc. The main customers are Nidec, Panasonic, Minebea, SONY, BOSCH, Brose, Wilo, JE, LG, Samsung and other internationally renowned brand companies and Rayleigh, Mingzhi , Ocean, Wanda, Weizhen and other well-known domestic companies, have been repeatedly rated as excellent suppliers by customers such as Nidec, Samsung, LG, Raleigh.
Bonded NdFeB magnet: the shape and size of the product are guaranteed by the mold, high dimensional accuracy, large shape freedom, can be made into shapes such as ring, tile, block, etc., without sintering and post-machining; variable number of magnetizing poles Various methods, the magnetic pole can be filled into multi-pole, oblique pole, the waveform can be square wave, sine wave. Bonded NdFeB magnets are widely used in automotive motors, hard disk drives, stepper motors, water pumps, oil pumps, DC motors, brushless motors, starter motors, and sensors.
Hot-pressed neodymium iron boron magnet: The product is a nanocrystalline structure with high density; high magnetic performance, the maximum radial magnetic energy product of the magnetic ring is 240-390kJ / m3; the magnetic ring is oriented in the radial direction, and the radial magnetic performance is uniform, which can make the motor Quiet operation and smooth torque output; the number of magnetizing poles and the magnetic pole helix angle of the magnetic ring do not need to be scheduled during the molding process, it can be achieved only by designing the magnetizing coil, and the customer has a high degree of freedom of use; the magnetizing waveform of the magnetic ring can be based on the user The magnetization is required to be square wave and other special magnetizing waveforms. Hot-pressed magnets have been used in various types of high-efficiency energy-saving motors such as automotive motors, power tools, servo motors, small precision brushless motors, and so on. The company is the second company in the world and the first in China to have the ability to produce hot-pressed NdFeB magnets in large quantities.
SmCo magnets: high operating temperature (maximum operating temperature is 550 ° C), temperature stability and chemical stability are far better than other permanent magnetic materials, without surface treatment can be long-term in high temperature, high humidity, strong demagnetization, nuclear radiation and other harsh Work in the environment. SmCo magnets (including SmCo5, Sm2Co17) are widely used in aviation, aerospace, military electronics, automotive, sensors, petrochemicals, magnetic transmission and other fields.
Plastic injection magnets (plastic magnets for short): Plastic injection magnets are molded using an injection molding process, so products can be designed into more complex shapes, as well as magnet components with shaft and gear inserts; and commonly used sintered magnets (such as sintered rare earth permanent magnets and sintered iron) Oxygen), the toughness of the injection magnet is better, and it is less likely to crack under the impact load. Injection magnets can be widely used in household appliances, automobiles, office equipment, 3C products and other fields.
