FIELD: manufacturing technology.
SUBSTANCE: group of inventions relates to production of hard-alloy press-billets for sintered cutting tools. Providing a composite matrix comprises feeding at least one front portion of the mold that can move in a first plane, feeding at least one transverse part of the mold, which can move in the second plane, alignment of said front part of mold and said transverse part of mold for setting cavity for press-billets. Direction of supply of said front part of the mold and said transverse part of the mold are oriented at an angle to each other. Formed cavity has at least one hole through which the male die can be introduced. Method of press-billets manufacturing includes feeder shoe feed through cavity hole and cavity filling with hard-alloy powder, powder is compacted by at least one male die that can move parallel to the main direction of pressing Z. Said transverse part of the mold is fed in the direction of supply parallel to the main direction of pressing Z.
EFFECT: making press-billets close to final contours.
