process chart
Raw material---melting--powder--pressing--sintering--magnetic testing--cutting&grinding--inspection--packing&shipping
Bonded magnet is made through "compression molding" or "injection molding" of the mixture of quick-quenched NdFeB magnetic powder and bonding agent. Due to its high accuracy in size, the bonded magnet may be formed into magnetic components of relatively complicated shapes.
Features:
1) Made by grinding sintered SmCo magnets
2) Mixed with resin and molded like Nd-Fe-B plastic bonded magnet
3) Produced without secondary processing
4) Highly resistant to corrosion
5) Free of coating Bonded SmCo Magne
