Compression bonded magnets are composed of a special form of NdFeB powder with adhesive and using compression molding techniques in simple tools, it can be quickly machined into complex shapes. Since its materials are isotropic, bonded NdFeB magnet can be magnetized in any direction or with multiple poles. Special magnetizing fixtures are required in order to achieve multiple poles magnetization, depending on complexity of design and production.
1.Excellent mechanical strength and surface finish;2.Compression molded magnets can be manufactured to very tight tolerances;3.Greater cracking and chipping resistance than other rare earth magnets;4.Superior energy to weight ratio;5.Can be molded into a variety of shapes and sizes;6.Magnetic values up to 10 MGOe;7.Single-time molding and multi-poles orientation8.Low tooling cost;9.Co-injected assemblies;10.Effective surface treatment to prevent corrosion;11.Widely applied in all kinds of mini-motors, auto motors, air-conditioner motors, automatic controlling devices, sensors, drivers, telecom and instrument industry;12.Stable working temperature: It can be high up to 150℃;13.The energy product is 3 times as large as anisotropic ferrite. The intrinsic coercive force is high. During the large-scale production, the magnetic properties are stable and conformity is good.
Injection Plastic NdFeB magnet is a kind of new generation composite material made from permanent magnetic powder and plastic. Injection NdFeB powder is blended with a plastic material and injection molded. With High precision of size, it can be made into complex shapes and also be bonded with other components. The injection molding magnet can be magnetized in any directions and with multiple poles.
