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 . Our factory produce and manufacture magnets according to customer's design on shape, dimension, grades, coatings etc. When inquiring, following information offered will be much appreciated . 1.Type of magnet (material & grade) 2.
