The injection molded magnet has a high mechanical strength and may be molded together with other matching parts.
1. Physical properties: High accuracy in size, high mechanical strength.
2. Manufacturing method:Single-time molding and multi-poles orientation.
3. Surface treatments: Effective surface treatment to prevent corrosion like epoxy resin parylene-coating. No bubble, no crack.
4. Magnetic properties: High temperature stability.The energy product is 3 times as large as ferrite. During the large-scale production, the magnetic properties are stable and the conformity is good.
5. Applications: mini-motors, auto motors, air-conditioner motors, automatic controlling devices, sensors, drivers, telecom and instrument industry.
