Clinching in comparison
Clinching versus other technologies

Joining with Elements & Riveting

Joining with elements
We use our know-how from the ClinchRivet® for other riveting-technologies
A simple, cylindrical rivet is pressed-in and formed during the clinching process. Without cutting the material the result is utmost strength.
Solid punch rivet
Solid punch rivets are mainly used for joining multi-layered sheet metals and metals that are hard to shape.
Semi-hollow rivet
In this joining-process due to the shape of the rivet and the die, the rivet is braced in the metal without cutting it.
Metal joining by inserting a joining-element into a drilled or punched hole which than is distorted.
TOX®-Systems for joining elements
You define the element - we deliver the equipment for handling, setting and joining.
