Folding


At the folding process the remaining overhangs after punching are folded over the edge by 180 ° and fixed. In the adhesive-free 3D-folding, the overhangs are shifted over the edge by means of matrix-patrix geometry and vacuum without a slide and by means using special 3D pressure frames welded or glued with a reactivated adhesive.

This process is used especially in the automotive industry to manufacture a variety of different components such as: ABC pillars, instrument panels, seat lining, door panels and more.
