FIELD: powder metallurgy, namely pressing blanks of charge with low content of plasticizer.
SUBSTANCE: method for pressing blanks from charge comprises steps of adding plasticizer in quantity 0.5 -1.0% to hard-alloy mixture; then pressing mixture.; before extracting blank from press-mold acting upon it by means of force impulse or set of force impulses whose value consists at least of 0.1 - 0.15% of specific pressing effort.
EFFECT: enhanced density, strength and strength uniformity of blank.
