FIELD: metallurgy.
SUBSTANCE: powder is loaded in the die mould, levelled and pressed in vertical direction in parallel to the item sides. Powder is loaded in the die mould via the slotted funnel in vertical direction in parallel with pressing direction with simultaneous powder levelling in the die mould by bottom shaped edges of the funnel slot by means of the slotted funnel movement using the support elements over the surface corresponding to profile of the item surface. By the shaped surface of the bottom piercer the shape of the other side of the item surface is formed. Funnel is used with slot edges made corresponding to the longitudinal shape of the side of item surface formed by the top piercer, at that the funnel and bottom pircer are made with possibility of movement parallel to the pressing axis.
EFFECT: increased uniformity of powders distribution and density in the item.
