Manufacturing Process for flat ceramic magnets:
1. Dry process:
By dry process, can produce isotropic & anisotropic magnets. The tool can be changed and developed easily.
2. Wet process:
By wet process, only anisotropic magnets can be produced. It is complicated to change the tool and the tooling charge is much higher.
Magnetization for flat ceramic magnets:
1. Isotropic ferrite magnets are not oriented and can be magnetized in any direction;
2. Anisotropic ferrite magnets are different, they are all oriented in the manufacturing direction, and should be magnetized in the direction of orientation.
