Riveting is an assembly process whereby controlled fusion and a change in shape of a pin, wing or plastic protrusion is used to lock or fix a component. The pin passes through a hole in the component to be fixed. Vibrations are added to the pin to melt and fill a cavity in the horn. The progressive fusion of the material under a generally small but continuous pressure forms the rivet head.
Riveting advantages are numerous including: short work cycle, rigid assemblies, removing screws and bolts, repeatability of results and simple design.
