Design guidelines
Distance between sheet edge and bend zone / between two bend zones Below you will find, per material type and sheet thickness, the standard die opening (V-opening) and the minimum internal flange dimension that must be maintained. This minimum dimension also applies to all holes and cutouts/contours in the sheet metal. If these fall within this minimum bend dimension, there is a risk of deformation of the hole and/or contour, which can cause the entire bend edge to pull askew and lead to unnecessary rejection. In the ‘Standard’ column, ‘Yes’ indicates the common combination of V-opening and internal radius per sheet thickness.

Cut contours near bend zones can deform during bending. Allow sufficient distance for this according to the tables. Bend depth for long products — bent products longer than 3,100 mm up to 4,000 mm may not be deeper than 380 mm. Otherwise a collision with the machine will occur.
Tolerances
Unless otherwise agreed, we apply ISO 2768-C (coarse).
| Tolerance type | Range |
|---|---|
| Length dimensions | ±0.2 mm (0.5–3 mm) up to ±4.0 mm (2,000–4,000 mm) |
| Angle tolerances | ±1.3° (small dimensions) to ±0.5° (from 400 mm) |
