FIELD: machine building.
SUBSTANCE: method comprises the placement of bimetallic billet composed of the core and envelope, into closed container and squeezing of billet through a conical hole with an application of effort to back end of pressed bimetallic billet. The lowering of effort of pressing at the expense of optimisation of angle of inclination of a matrix, forming the conical bore, is ensured that use a matrix, the angle of inclination of generatrix of the conical passage to pressing axis is regulated by the mathematical expression.
EFFECT: lowering of effort of pressing and energy consumption by process of pressing of bimetallic bars and wire from bimetallic billets.
