4 Points Clinching machine

The Clinching process uses a button-type, positive connection of two or three layers of sheet metal using a cold-forming process，without heat or additional elements. Due to its cost effectiveness and reliability, Clinching is widely used by the whole sheet metal working industry.

What is CLINCHING:

Clinching offers all the components needed for the joining technique, according to DIN 8593 of the production technology. With the clinching process sheet metals of different thicknesses or other materials, also with adhesives or other intermediate layers are joined in a cold forming process.Applied in many industries,like in the automobile, white goods and computer industries, as well as equipment Integrators confirm the clinching machine is cost effective.

In the Joint process, the material strain hardening in the neck area and the lacking of any notch effects produce the high retaining forces. As it is the direct result of the fixed, rigid die. Static strength up to 70% of a spot weld, by positive strain hardening, without damage to the surface coating and typically more economical.Corrosion tests have shown that because the surface coating is not damaged during the round joint process, the anti-corrosion coatings of the joined sheet metals, e.g., aluminum or galvanized, are maintained.
