  Why Orbital Riveting Process  
  Orbital Riveting Process is one of the most versatile process of cold forming of metals. The deforming force has to be so large that the stresses in the deforming region reaches the value of YIELD STRESS of that material. At this value of stress the material starts flowing and the riveting head is formed. In conventional method the force is applied by a hammer or by a pneumatic or hydraulic cylinder on a punch. Theoretically the riveting force required is the yield stress of the material multiplied by the area of the rivet shank in contact with the punch.

In ORBITAL riveting process the riveting tool (or punch) is inclined with respect to the rivet axis. This reduces the area of contact between the punch and the rivet shank. Thus the riveting force required is reduced drastically. The inclined riveting tool also rotates around the axis of the rivet. This result in very gentle deformation of the material.
