Air Bending

Air Bending is a frequently used, flexible bending method. In Air Bending , the workpieces is in contact with the upper and lower tools at three different points.

Any angle between approx. 32° and 180° can be produced without changing tools
Low bending tonnage requirements

Coining

In Coining, the bend angle is produced in a form locking manner, i.e. by pressing the workpieces into a defined form (loower tool, or die). The angles of the upper and lower tools must be idntical, they determine the workpieces angle.

If the required inside radius of the workpiece is less than the sheet thickness.
If holes, cutouts or angled edges are located near or on the bending line.
Extreme contour accuracy
Cost efficient on large series production

Hemming

In Hemming, a seam is produced along a sheet edge using special tools.

If a seam does not need to be pressed completely flat
To minimize the counter-bend effect in long seam flanges
If a defined dimension needs to be producedbetween the flanges

Flatenning

In Flattening, a seam is produced along a sheet edge using special tools.

Flatenning is used when a seam is to be pressed completely flat
