FIELD: process engineering.
SUBSTANCE: proposed method comprises forming hook on article with sharpened and conical sections and drawing through tapered channel of monolithic drawing die. Reduced drawing stress and increased signal reduction are ensured by optimised angle of inclination of drawing tool tapered channel generatrix. Note here that said angle is set subject to such parameters as drawing, external friction factor, resistance to core and shell metal strain, relative areas of core and shell, etc.
EFFECT: reduced drawing stress.
