Self-Pierce Riveting (SPR)

Self-Piercing Rivet Solutions

The metal-layers are placed between the stripper and the die. With the motion of the punch, the rivet cuts through the first layer. Based on the shape of the die and the rivet, the rivet spreads into the die side layer. Check out the diagram below for a visual on how the self-pierce riveting (SPR) process works.
