Research methods - mathematical and physical modeling, as well as experimental research. Methods of reducing the spring of the part on the example of the prototype process of pulsed sheet metal stamping are determined. For this purpose, technical solutions are proposed and EHS modes are defined. For the first time, the influence of the rate of contact interaction of pre-unloaded high-strength sheet steels with the matrix in the conditions of EHS on the relaxation of tangential stresses, which lead to a decrease in the adhesion of manufactured parts. The results of field tests showed that the spring value of automotive parts B-Pillar "Ford motors", made by pulsed stamping of DP780 steel, is 5-8 times less than the spring of parts made mechanically. Recommendations for the design of technological processes that ensure high accuracy of the finished part within 9-11 qualities, made by pulse stamping or calibration.
