Under the name of RIVTAC®, the Böllhoff Group presents a new joining method for diverse industrial sectors
Under the name of RIVTAC® the Böllhoff Group in Bielefeld, Germany, has developed a future-oriented joining method for diverse industrial sectors such as the automotive industry.
The worldwide unprecedented technology is a type of high-speed joining particularly suitable for profile-intensive composite constructions with small wall thicknesses. Even in case of one-sided accessibility, no pre-punching is required. A special plus are the very short cycle times of less than 1 second.
In the process, a nail-like auxiliary joining part is accelerated to high speed and driven into the not pre-punched joining parts. The pointed tack displaces the material without forming punchings. During penetration, the material experiences a significant temperature increase which allows higher degrees of deformation. With RIVTAC®, also ultra-high-strength parts and profiles with a strength above 1,000 MPa as well as multiple-layer joints can be joined without loss of performance.
