Tooling selection: clinch area and thickness

The main parameter for selection is the clinch area.

It is general defined by the edge of the sheet metal wall. The width or the diameter of the die must mach the edge width (A) so that the die’s outer dimension is at least equal to the sheet metal edge.
On punch side, the limiting dimension will be the width of the stripper front piece. A special stripper front piece may be provided in case of limited access.
