FIELD: process engineering.
SUBSTANCE: invention relates to metal forming and may be used in producing thin-wall shells from low-plasticity aluminium alloys by rotary drawing. Prior to rotary drawing, thick-wall billet is heated to temperature making 0.5-0.6 of aluminium allow high annealing temperature. Rotary drawing is performed with billet thinning. Produced thin-wall shell is subjected to thermal treatment to impart preset mechanical properties to aluminium alloy and final cutting.
EFFECT: higher precision and surface quality.
