Abstract:
     The present invention is related to the production method of anisotropic hard magnetic components in which ferrite magnetic powder of Ba, Sr and other elements is firstly mixed with paraffin wax, the mixture is then injected and shaped under certain magnetic field by a special hot pressing injector, and the semifinished products are finally sintered. The said method is applicable for producing small anisotropic hard magnetic components with high performance and complicated shape. The characteristics of the said method are:1 ease to shape small semifinished products with complicated shape and precise dimensions, and high shaping efficiency; 2 higher orientation ability and high magnetic performance compared with the case of the dry-shaping method under a magnetic performance compared with the case of the dry-shaping method under a magnetic field; 3 ease to mass-produce and stable performance; 4 ease to magnetize the components in any direction and to make the components have ......
