The article presents the results of investigation of the swaging process in a spherical ar-
ray and exhaust by spherical punch at manufacturing the bottom part of high pressure
cylinders. We have built diagrams of deformation in different parts at swaging and ex-
haust by spherical punch. Polythickness value is established for two technological ways
of manufacture. Comparison of the experimental data and the results of theoretical study
showed satisfactory convergence. Comparison of the experimental data and the one
obtained in the ANSYS LS-DYNA proved correctness of the chosen models to study the
wall thickness.
