A method for placing a functional element, especially a fastening element, in an especially liquid-tight and/or gastight manner, on a metal part. The inventive method is characterized in that a functional element provided with a hollow head segment is pressed against the metal part ( 212 ) which is supported by a die ( 214 ) and the metal material is deformed into an undercut ( 324 ) by deforming the head segment when simultaneous deformation of the hollow head segment occurs and the metal pant is shaped in a forming area defined by parts ( 216 ) of the die ( 214 ). Said parts ( 216 ) are kept in a stationary position during the forming process but are partially removed from the die to enable the functional element which is placed on the metal part ( 212 ) to be extracted therefrom. The invention also relates to a die, a functional element, an assembly element and a die arrangement. |
