Production processes of compression bonded NdFeB magnet:
Isotropic Material
Magnetic powder&Couple Agent→Binding→Materials→Pressing/Forming
(Magnetic filed free)→Curing→Surface Treatment→Magnetizing→Inspection→Packing→Delivery
Anisotropic Material
Magnetic powder&Couple Agent→Binding→Materials→Pressing/Forming
(With Magnetic filed)→Demagnetizing→Curing→Surface Treatment→Magnetizing→Inspection→Packing→Delivery
Features
1.Max. Working temp.160℃;
2.Molding processed, economical and full automated manufacturing;
3. Reliable corrosion resistance, various coatings (Epoxy, parylene, Everlube, paint, etc.) ensure corrosion resistance and product appearance;
4. Magnetized methods variously, multipole axially, radially with skew angle, Halbach Array. Make motors performances more efficient, less noise at high speed rotation.
