The invention relates to a molded part (l0) which is configured by initially forming a tubular body (2) with a soldered flange (7). Subsequently, the body (2) is shaped in a mold (8) by securing the flange (7) under high internal pressure to shape the form part or the preform (10). Thus, preforms with a secured flange that can be used to connect said preforms to other parts can be easily obtained
L'invention concerne un procédé pour la fabrication d'une pièce moulée (10), dans lequel un corps tubulaire (2) est d'abord pourvu d'un bord soudé (7). Ce corps (2) est ensuite façonné dans un moule (8), avec blocage du bord (7), par formage sous haute pression interne pour former la pièce moulée ou le corps moulé (10). On obtient ainsi, simplement, des corps moulés pourvus d'un bords de fixation permettant l'assemblage du corps moulé avec d'autres pièces.
