Selecting clinching machines process metalClinching conjoins metal workpieces by deforming two metal substrates, so that the underlying workpiece partially envelopes the downward depression and lateral flow of the overload workpiece. This is accomplished by a clinching machine that consists of a punch and die. The die may be static or contain articulating blades to help form and release the clinch joint upon its completion. When the clinch is complete, the top workpiece will feature a small cylindrical depression, while the bottom piece contains a button-shaped extrusion.

 

No external hardware or consumables are required, and no sparks or fumes result. Substrates are not subjected to heat or a charge, meaning this process will not affect surface treatments or coatings. Clinches can be formed with minimal tolerances and are vibration resistant. Clinching is a highly-repeatable, reliable, timely, and economical means of conjoining metal substrates.
