Staple - Clinching

For specific requestes, for example in fornitures sector or industrial dampers, with the use of Galvanized steel, prepainted or plastic is suitable use the technique of stapling or clinching. We can obtain with these techniques a closed profile without the use of welding, to safeguard the coating in the junction area.

The stapling is an union of the flaps with double turned fold on itself, smash to dry and stamped with micro-incisions to wheat or to fishbone, to create greater cohesion between the edges of the strip.

Clinching is the union of the strip edges, perfectly adjacent, with the aid of a special machines which compresses a flap above the other, enlarging the first inside the second, ato a desired pressure proportional the thickness of the belt, the frequency is defined by the need to seal in a different way.
