Abstract

EN EL METODO DE PRENSADO EN MOLDE DEL POLVO DE IMAN PERMANENTE Y DEL POLVO FINO, EL POLVO SE RELLENA EN UNA ALTA DENSIDAD EN UN MOLDE DE GOMA (10), OCASIONALMENTE SE MAGNETIZA DE FORMA PRELIMINAR (4A) EN EL MOLDE DE GOMA Y SE COMPACTA ENTONCES BAJO UN CAMPO MAGNETICO O SIN UN CAMPO MAGNETICO. SE EVITA LA FRACTURACION DEL MATERIAL COMPACTO MAGNETIZADO. PUEDE PRODUCIRSE UN MATERIAL COMPACTO SINTERIZADO QUE TENGA UNA DENSIDAD DEL 90% O MAYOR USANDO POLVO FINO.
