The handheld clinching unit is a manual/semi-automatic tool utilizing cold-extrusion rivet-less clinching technology. By applying high pressure to two or more layers of metal sheets through the tong-head dies, it induces plastic deformation and interlocking of the sheets, forming a robust point-connection structure.

It is widely applied in the joining scenarios of metal components such as air dampers, sheet metal, automobiles, home appliances, and HVAC equipment. It is especially suitable for the rapid clinching of materials such as thin steel plates (typically 0.8-3.0 mm), stainless steel plates, and aluminum plates.
