The results of an experimental verification of the obtained theoretical formulas are presented, which make it possible to determine the most important parameters for extruding glasses with a counter-punch for different cavity radii and bottom thicknesses. The characteristics of the tools used, the geometric parameters of the extrusion experiments, the strength characteristics of deformable materials, and their lubrication are described in detail. Extrusion studies of both non-hardening and hardening material have been performed. The methodology for performing theoretical calculations is shown in detail. The high accuracy of the calculated calculation formulas is confirmed.
