FIELD: powder metallurgy, namely processes for pressing elongated complex-shape articles, possibly in machine engineering.
SUBSTANCE: method is used for pressing elongated articles of powder in press-molds with die having horizontal parting. Method comprises steps of pouring powder to lower part of die, drawing together upper and lower parts of shaping die; shifting powder by moving lower punch to upper part of die and pressing it. At extraction article from press-mold its upper part is released due to opening upper part of die along one or several planes passing along (or parallel to) vertical and(or) inclined axis of upper part of pressed article. Simultaneously upper and lower parts of press-mold are opened along horizontal parting plane.
EFFECT: enhanced quality of article, enlarged manufacturing possibility at making complex-shape articles.
