Bonded neodymium iron boron magnets are magnets made by mixing rapidly quenched NdFeB magnetic powder and binder through "compression molding" or "injection molding". The dimensional accuracy of bonded magnets is extremely high, and they can be made into magnetic element devices with relatively complex shapes, and have characteristics such as one-time molding and multipole orientation. The injection magnet has high mechanical strength and can be integrated with other supporting components during molding.
Main features:
Bonded neodymium iron powder has the highest magnetic properties and can be magnetized in any direction. It can magnetize circular magnets radially and multipole, and can
produce complex magnet shapes. The magnetic powder is coated with heat-resistant plastic and additives to provide excellent temperature stability, and the special resin coating ensures its good performance
Good corrosion resistance.
Our products include ring, tile, and special shapes, and we can also design special magnets according to user requirements (product length can reach 50MM, aspect ratio can reach 3, thickness can reach 0.35MM, and weight can reach 0.06g). Its products have the following characteristics:
Can be magnetized in any direction; 8 pole, 16 pole, 24 pole, 32 pole and other multipole magnetization;
With high-precision dimensions, the tolerance range can be controlled within 0.02MM;
Various shapes and specifications, and can produce thin-walled magnets with a thickness of around 0.6MM;
Advanced surface treatment technology can effectively protect magnets from corrosion;
Good temperature stability, with a maximum operating temperature of 150 ℃;
The maximum magnetic energy product reaches 12MGO. Our company has advanced and unique magnetization technology,
According to user requirements, various types of magnets can be subjected to multi-pole magnetization in axial, radial, planar, and other directions. The magnetization waveform can be adjusted according to user requirements,
To achieve the magnetic field waveform required by the user. The company's research and development center can provide comprehensive technical services to users.
