FIELD: metallurgy.
SUBSTANCE: at moulding material of tube stock of oval cross section is directed to zone of bench making with simultaneous performing axial breaking down with moulding loads applied to ends of tube stock and cross breaking down of tube stock with moulding loads applied to side surface and at exerting internal pressure of filler. Also the tube stock is directed with big axis of oval cross section to a zone of to be made branch; moulding loads of axial and cross breaking down are generated with counter motion of puncheons at an angle to lengthwise axis of the tube stock; notably, this angle is different from the direct one; end cross sections of the tube stock are turned for directing motion of tube stock material located between moulding puncheons into the zone of to be made branch.
EFFECT: upgraded quality of parts.
