The subject of analysis is the real process of continuous extrusion of copper section on a Conform machine with a prechamber. The machine is operated at the Kamensk-Uralsky Non-Ferrous Metal Working Plant. Perlin's method is used, which involves determining the total pressing force, to calculate the following stability-critical parameters of the Conform process: the length of the split container (which should be such that the frictional force on its movable surface be sufficient for extruding the metal from the prechamber to the die hole), the wheel torque, the power of the electric motor. Comparing the calculated and measured data shows that the discrepancy is less than 8%. The derived equations are simple and easy to use in technical and technological design of the Conform process with prechamber, which is exactly the purpose of this study.
