Tall extrusion power accompanies the technological process, that will be brought on by high deformation opposition and large friction weight in extrusion problems. As a result of large thermo-mechanical loads affecting the die, an important loss in dimensional reliability of extruded pages may be seen. The various tasks of porthole dies when it comes to extrusion of Ø50 × 2 mm tubes through the 7021 alloy were numerically calculated and then tested in industrial problems by utilizing a press of 25 MN ability design
