Process and machine for producing hollow metal articles by configuring tubes and articles, at least in the area where they have to be configured, at a temperature at which the metal becomes easily malleable, the forced introduction of compressed air and another suitable gas for to establish an adequate pneumatic pressure inside the hollow article without adversely affecting its material, thus forcing itself outside the wall of said hollow article in said area against a shaping and delimiting member, and releasing the pressure before or after cooling.
