Abstract

Dans le procédé selon la présente invention, on chauffe un flan 12 en métal, on recouvre au moins une des faces dudit flan 12 par une couche calorifuge 14 d'une matière compressible et résistante aux hautes températures puis on chauffe ladite couche isolante 14 et on applique une pression de formage à l'ensemble comprenant ledit flan 12 et ladite couche calorifuge 14 pendant que cette combinaison est à l'état chaud, la pression étant transmise audit flan par l'intermédiaire de la couche isolante 14.In the method according to the present invention, a metal blank 12 is heated, at least one of the faces of said blank 12 is covered with a heat-insulating layer 14 of a compressible material and resistant to high temperatures, then said insulating layer 14 is heated and said insulating layer 14 is heated. applies a forming pressure to the assembly comprising said blank 12 and said heat insulating layer 14 while this combination is in the hot state, the pressure being transmitted to said blank via the insulating layer 14.
