THETA® clinching is an innovative further development of the conventional clinching process. The targeted heating of the material combination using a laser before the actual clinching process signifiantly increases the formability of materials. This enables a reliable mechanical connection even with materials that are difficult or impossible to clinch under normal conditions - including high-strength and ultra-high-strength steels as well as low-ductility die-cast aluminium alloys and aluminium sheets.
Thanks to the combination of thermal pre-treatment and proven clinching technology, THETA® opens up new fields of application in modern lightweight construction, particularly in the automotive industry.
