Abstract

Procédé de fabrication d’un profilé par extrusion et forgeage , profilé ainsi obtenu L'invention a pour objet un procédé de fabrication d’un profilé combinant une étape d’extrusion d’une ébauche (40) suivie d’une étape de forgeage de l’ébauche (40) pour obtenir le profilé. Cette solution permet d’obtenir un profilé qui présente une plus grande dimension finale supérieure à la valeur maximale autorisée par un dispositif d’extrusion. L’invention a également pour objet un profilé obtenu à partir de ce procédé. Figure 5
