Clinch

Cold joining method of metal sheets

The clinching process is a method of joining sheet metal or extrusions by localized cold-forming the materials.

The result is an interlocking friction joint between two or more layers of material formed by a punch into a special die.

Coated and painted sheet metals can also be joined together with no damage to the surface finish.

With the aid of punch/die combination an extremely strong snap-fastener type joint is produced.

The joining technique can be used to join steel and stainless steel materials as well as aluminum and or non-ferrous materials in a cost effective, environmentally friendly process.

Depending on the choice of joining tools, the resulting joint can be round or rectangular:

•Round joining is for sealed joints with no surface cutting.

• Rectangular joining incorporating surface cutting, particularly for very hard materials or stainless steel.
