The invention relates to a method for producing a hollow profile using a metal forming method under high fluidic pressure. According to said method, the surface of sheet metal is specifically provided with structural elements (2), which increase the maximum moulding degree of the component in the subsequent hydroforming process.
La présente invention concerne un procédé pour produire un profilé creux en utilisant un procédé de formage à haute pression fluidique. Selon ce procédé, une tôle est pourvue de manière ciblée, à sa surface, d'éléments structurels (2) qui augmentent le moulage maximal du composant lors d'un formage sous haute pression ultérieur.
