Abstract

Method to increase the ductility of an article in an embossing process, and especially to enlarge the diameter of a portion of at least one tube, maintaining uniform the thickness of its walls, characterized by the following phases: apply a fluid under pressure inside and outside the tube to make it ductile; increase the pressure of the fluid inside the already ductile tube, to widen its diameter; and apply a force, while expanding the diameter, to one end of the ductile tube, in order to longitudinally compress the material thereof.
