Q:how are magnets made?
¡ê¨¢¡êomodern magnet materials are made through casting, pressing and sintering, compression bonding, injection molding, extruding, or calendaring processes.
Q:how rare earth magnets are made ¡ê
¡ê¨¢¡êomining => melting => milling => aligning&pressing => sintering => inspecting => machining => plating/coating => inspecting => magnetization => packing&shipping .
