What is Clinching?

Clinching joins sheet metal by drawing and forming the part materials into an interlock. Using the part material improves production time and cost while eliminating welding and fasteners. It is an environmentally-friendly process – no sparks, fumes or heat.

When to Use Clinching

BTM equipment and tooling can clinch 2 or more layers with combined thickness from 0.2 mm to 7.0 mm. Clinching is effective for a wide array of metal alloys and combinations and is applicable to sheet metal with pre-painted surfaces, galvanized surfaces and other finishes. Clinching can also be used to join certain non-metals, like filter cloth, to parts made of sheet metal.
