Compression
bonded magnets are made by using many isotropic Neodymium, Iron, and Boron materials, as well as crushed & powdered Samarium and
Cobalt ingredients. Combinations of different elemental grades are used to create specific magnetic properties. Compression
bonded magnets offers higher magnetic strength than
injection molded magnets due to their higher magnetic particle density, but is unfortunately limited to simple geometric shapes due to the compaction process. The epoxy used is very resistant to normal industrial solvent and automotive fluids.The normal applications of these
magnets range from below -40℃ and beyond 165℃.
1. High quantity and even volume manufacturing, with up to millions of pieces per year.
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.
