Abstract

Procedimiento para preparar un cuerpo integral de pulvimetal con partes de diferentes densidades, caracterizado porque comprende las etapas de: (a) prensar pulvimetal en un molde por lo menos con una profundidad múltiple troquelada para producir un compacto de pulvimetal que tiene partes de mayor longitud con relación a la longitud de otras partes del compacto; (b) sinterizar el compacto del pulvimetal; (c) volver a prensar el compacto sinterizado en un molde con un troquel que aplica fuerzas principalmente en las partes del compacto sinterizado de mayor longitud; (d) recuperar el cuerpo del pulvimetal donde las partes que inicialmente tenían una mayor longitud tienen una mayor densidad que las partes que incialmente tenían una menor longitud.
