FIELD: technological processes.
SUBSTANCE: method includes cable twisting from wire and its coiling onto mandrel with simultaneous kinking and stretching of wire in single operation, cutting of spring with specified length, welding of cores, thermal treatment, measurement of geometric and power parameters and application of protective coating. At that polished or patented wire is used, which is exposed to high-temperature thermomechanical treatment prior to cable twisting and winding on mandrel.
EFFECT: higher resistance of springs and reduction of its deviations in height.
