    Samarium Cobalt Compression Bonded Magnets are made by utilizing the technique of compressing an epoxy coated SmCo magnet powder into a final shape and then heat treating it. The result is a high density material which produces a higher magnetic output than by injection molding. Although compression molding provides greater flexibility in geometry shape and size, they do not provide the range of complex geometries which can be achieved by injection molding. The following tables list common grades, however custom grades can be made depending on customers’ requirements.

    The factory offers both compression bonded 1:5, and 2:17 SmCo magnets. They have lower energy products than sintered SmCo – currently in the range of 4.0 to 10.0 MGOe.
    Polymer samarium cobalt magnets with SmCo magnetic powder mixed with polymer materials, compressing through the shaped die, various shapes of high dimensional accuracy can be produced, requiring no further finish machining. Due to excellent corrosion resistance, coating is not required.

    The factory has over 15 years experience on manufacturing and technology on the polymer samarium cobalt magnets, Bonded Samarium Cobalt Magnets. With its own molding workshop, the factory can accomplish entire production process in-house from molding design, manufacturing and maintenance. The plant has obtained automatic production with rigorous Japanese-type management and precise equipments imported.
