FIELD: technological processes.
SUBSTANCE: method includes coiling of spring from polished or patented wire with pitch that exceeds pitch of finished spring, thermal treatment, shotcasting riveting and spring pressing by means of its yield by axial load of (10÷300) F3 value, where F3 is spring force at maximum deformation. At that high-temperature thermomechanical treatment of wire is carried out prior to spring coiling.
EFFECT: spring operational properties are improved.
