Round Clinch

Rectangular Clinch

Clinching is a circular, leak proof joint formed by drawing the metals into a circulate "cup" and then expanding the diameter to form a 360° radial lock below the bottom sheet.

Clinching system joins sheet metals, extrusions and formed metal components. Steel, aluminum, brass and other metals can be joined, including coated and painted stock,. Thickness ranging from ( 2) layers x 0.2 mm up to a combined total thickness of 8 mm ( 320 ") can be joined with readily available standard tooling.

The metals are joined by a local deformation which creates a strong leak proof interlock. Simple mechanical punch and die tooling is used to produce the joint.
