Method and apparatus for producing anisotropic rare earth magnet.

摘要

A method for producing an anisotropic rare earth magnet is improved by applying compressive stress on a free surface of a compacted material at the time of extruding the compacted material in order to prevent forming cracks, and improved by using a double action punch provided with a core punch and a sleeve punch so as to mold a compacted material and extrude the compacted material into the anisotropic magnet material in a single heat process continuously.
