ABSTRACT:
In the production of press molded articles, such as permanent magnets made from anisotropic powder materials, a more nearly uniform distribution of the particles is obtained by the forming of a preliminary series of articles, each being only a fraction of the length of the final product, after which the preliminary articles are combined under lengthwise pressure in a mold. Pressure may be applied as each preliminary article is added in the mold and the final article may be sintered or a plastic binder may be added and cured by heating.
