2. High accuracy in size.
The bonded magnet may be formed into magnetic components of relatively complicated shapes.
3. Single-time molding and multi-poles orientation.
4. The injection molded magnet has a high mechanical strength and may be molded together with other matching parts.
5. Effective surface treatment to prevent corrosion.
Good corrosion-resistance and nice surface: The product is coated with epoxy resin parylene-coating and the anti-corrosion is very good. The surface is smooth, clean and nice-looking. No bubble, no crack, no strip-off, and no chip.
6. Stable working temperature.
The working temperature is high up to 150℃.
7. Excellent magnetic properties.
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 the conformity is good.
8. Application to Bonded NdFeB.
Widely applied in all kinds of mini-motors, auto motors, air-conditioner motors,automatic controlling devices, sensors,drivers,telecom and instrument industry.
