FIELD: metallurgy.
SUBSTANCE: method comprises preliminary shaping on an article of a cach and further multi-pass drawing through monolithic drawing dies. Exclusion of a possibility of product destruction caused by axial, radial and circumferential residual stresses is ensured by the fact that limit total drawing is specified, on the basis of the metal product strength preservation, by a mathematical relationship.
EFFECT: invention is intended for production of axially symmetrical rod- and wire articles by drawing.
