Abstract

L'invention porte sur un procédé de fabrication qui comprend une opération pour disposer N-1 pièces de moules de transport (10) entre des parties de bobine (111) qui sont coaxialement conçues pour N étages (N est un entier de 3 ou plus) et pour orienter radialement une poudre magnétique dans les moules de transport (10) avec un champ magnétique opposé généré à partir des parties de bobine adjacentes (111), une opération pour pressuriser une poudre magnétique dans les moules de transport (10), une opération pour démouler un comprimé annulaire orienté et pressurisé à partir du moule de transport (10) et stratifier une pluralité des comprimés annulaires et un procédé pour fritter et intégrer les comprimés annulaires stratifiés. Les parties de bobine (111) génèrent un champ magnétique alternatif dont l'amplitude s'atténue avec le temps.
