Hengdian Kim Dae magnetic field strong magnet factory ---- how to shield powerful magnets or magnetic NdFeB magnets are particularly big, sometimes interfere to some electronic products. In air transport electromagnetic products have certain restrictions. Now in the domestic air transport of magnetic products are prohibited in the international transport of electromagnetic products also have very strict regulations. We have a way to get these objects magnetic field does not affect or reduce the effects of it? Yes, that is shielded it. Our common ordinary iron magnetic shielding. Higher magnetic shielding requirements requiring high magnetic permeability material, the material to meet this requirement is an iron-nickel alloy, which material has a high permeability. When the need to shield the magnetic field is strong, with only a single layer of magnetic shielding material covered buttons raw materials, not reach the shielding requirements, that saturation will occur. In this case the magnetic clasp type package, a method is to increase the thickness of the material. But more efficient method is to use a combination of magnetic shielding bag buckle unit price, a shield over the other shield body, leaving an air gap between them. Can be filled with any non-permeability material support to do within the gap, such as aluminum. Much higher than the shielding effectiveness of a combination of shielding single shield, so the combination of weak magnetic shield can be reduced to a very low level. Hengdian Kim Dae-magnetic NdFeB magnet factory ----- What made out of NdFeB magnets are made out of what? First of NdFeB magnet manufacturers need first to understand that it is necessary to contain alloy materials crushed into particles, these particles come together forming, and then sintered. Then cut off into desired size to complete. Of course, magnetic buckle bag, in the actual production of high-quality NdFeB magnets is not so simple. Not only to the unity of 3 ~ 5μm particle size, but also pay attention to the uniformity of shape, but also consider the heating methods such as sintering, it takes a lot of work to make. Magnetic buckle bag models _ Kim Dae-magnetic plant the best choice (certified) _ Ningbo magnetic buckle package offered by a large magnetic Hengdian gold plant. Hengdian Kim Dae-magnetic Factory (www.jjdct.cn) is an industry leader in Jinhua, Zhejiang, electronics, electrical products manufacturing equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs . In the Kim Dae-magnetic plant leadership with the staff warmly welcome all inquiries negotiations to create a large magnetic gold plant a better future.
