The Radial Riveting System

Radial riveting system

The radial riveting system represents a vast improvement over other forms of riveting processes - the rivet head is formed with very little effort, and the material flows:

  • Radially outwards
  • Radially inward
  • Tangentially

The combination of these flows of material offers a riveted joint of excellent quality.

This diagram shows the movement of the head, forming the head of the rivet of into a semi-sphere and the diagram to the right shows it in better detail.

The radial riveting process originated in Europe, in the mid 1960s. The process is used for various other applications beside riveting.

Today, this process is the only one able to configure assorted materials. The versatility of the radial forming process has made it the worldwide market leader.

Orbital forming graphic


A common misconception is that radial forming is the same as orbital forming, but there are large distinctions between the two processes.

Radial forming displaces the material uniformly, at a constant speed. It is done in an 11-sided rosette pattern to ensure the displacement is uniform, and that it displaces the material consistently. The radial riveting process results in higher joint strength, and a superior finish.

Orbital forming displaces material at different rates when examined outwards from a part's centre.
