FIELD: technological processes.
SUBSTANCE: method for manufacture of profile shells includes blank installation and fixation on profile holder, molding by means of rotary drawing in several passes. Molding is done with deforming rollers with separation of deformation between passes by means of rotary drawing in the form of rotary drafting and rotary deformation of wall, and also between rollers by means of their axial displacement.
EFFECT: high stability of molding process, reduction of passes amount and manufacture labour intensity.
