The design of the process for industrial testing of a new method for manufacturing glasses with a flange in the bottom part by direct extrusion with counter-punch is shown in detail. The drawing of the resulting product is given, the requirements for it are set out. It is shown that on presses with a low working speed, the counter-punch resistance cannot be ensured. It was proposed to use the temperature effect of plastic deformation, which manifests itself above a certain rate of deformation and eliminates the increase in force due to hardening of the extruded material, to ensure an acceptable load on the counter-punch.
