Fast, low-cost assembly alternative to spot welding, rivets, and screws. Manual or automated assembly solutions are available.
The process is known as clinching which cold-forms the part metal using a special punch and die to form a strong interlocking clinch joint. The result of the process is a round, button-shaped extrusion on the die side of the assembly, and a small cylindrical cavity on the punch side. The clinch joint requires only the sheet metals that were joined.
