The cross-sectional area of electrical contacts is the most important characteristic of their resilient and reliable operation. Increase of the area leads to the boost of the number of electrons passing through the cross-section over a period of time, which magnifies the current density. Manufacture of electrical circuit contacts requires techniques that allow keeping the cross-section area of the finished part unchanged. Below, we present experimental data on the bending of flat plates to obtain contacts with a bent axis. Statistical processing of the experiment results on the bending of flat electrical contacts shows that thickness of the finished product at the bending point neither significantly changes and nor depends on the method of plastic deformation. However, the average thickness of the plate bent with increased edging support is 5% larger than the plate obtained using the traditional technology. Although these results lie within the range of permissible errors, they make it possible to evaluate the effect of the support on the geometry of the cross-section of the detail. There is a tendency to an increase in the thickness of the electrical contact with curved axis during its manufacture by the method of bending with the support of the plate ends. The results obtained are intermediate (a small experiments number, optimal deformation conditions selection), however, they make it possible to determine the further developments directions in the problem of increasing the electrical contacts cross-sectional area manufactured by pressure treatment methods.
