In this joining process, a distinction is made between direct and indirect press riveting. In direct press riveting, the rivet nut or stud is first fully inserted into the pre-drilled pilot hole. The protruding rivet shaft is then deformed with a riveting die under high axial force.

Indirect press riveting means that the deformation of a rivet happens simultaneously to the positioning into the pre-drill. The rivet is pressed against a stationary die.

This joining method can be used not only for connecting parts. High-load functional fasteners like ball studs, which are used in hoods, trunks and doors, can also be riveted. In general, ball studs have to withstand extreme side loads. Therefore, we developed a high-load rivet ball stud and a corresponding setting head for press automation.
