Injection molding magnets

With the update of science and technology in magnetic industry, some more efficient and low cost magnets have been urgently demanded for responding the newest challenges and opportunities by great amount of customers, Injection molding magnets is a typical one.

A important development in magnetic industry, the polymer magnets have provide some new applications for customers to get benefits. One of the benefits that polymer magnets brings to is injection molding magnets are simply to be shaped or blended since the magnet material could be molded into, onto, or against other assembly components eliminating subsequent assembly steps directly. In addition, compared with sintered ferrite, injection molding magnets are lighter, high dimensional stability and magnetic design degree and hard to crack. Injection molding magnets could also been adopted to design for various types of load magnetic device.
