WORKSHOP #2 | Fastening & Joining: New & Alternative Methods
Clinching and Self-Pierce Riveting for Mixed-Material Assembly
As engineers incorporate a greater mix of materials into their product designs, two joining methods—clinching and self-pierce riveting—are gaining attention as alternatives to spot welding. Self-pierce riveting (SPR) is a cold joining process for fastening two or more sheets of material by driving a rivet through the top sheets and upsetting it, under the influence of a die, into the bottom sheet without breaking through it. The process can join high-strength steel, galvanized steel, aluminum, plastics and composites. In clinching, a punch and die are used to plastically form a mechanical interlock between metal sheets. The process can join metal sheets of different thicknesses or materials. It can even be used on stainless steel. This presentation will cover everything you need to know about these two joining processes.
