The present invention relates to a tool portion for a forming tool and a method for manufacturing such a tool portion. The tool portion comprises a material piece (8, 30a, b, 49) having a specifically shaped surface (1 1 , 33a, b, 50) and a material layer (7, 29a, b, 51) which is formed after the specifically shaped surface (11 , 33a, b, 50) of the material piece (8, 30a, b, 49) during a hydroforming process. The material layer (7, 29a, b, 51 ) comprises a surface (6, 26a, b, 48) which is intended to come in contact with and form blanks (3, 23, 42) which are formed by means of the tool portion. |
