The services offered by Ense S.r.l. to its customers include sheet metal bending, a technology that  obtains permanent deformation by means of a flexural action.

Metals have a “neutral fiber” that can be deformed, without being stretched or contracted. The good outcome of the operation depends on the properties of the metal, which must have a suitable plasticity to avoid cracking in the proximity of the bend.

Similar tasks require high expertise in order to determine and correct the spring back, if necessary. During bending, the internal fibers are heated and the external fibers are stretched, generating an inward translation of the neutral fiber.

Air bending

Air bending uses an upper punch to press the plate in a V-shaped lower die. Three are the contact points between the plate and the machine: two on the die and one on the punch. The operator will determine the bending angle, which depends on the depth of the punch.

The process takes into consideration over-bending, which literally consists in obtaining a bend higher than necessary to make up for the spring back and obtain the desired angle. The technical staff of Ense s.r.l. will always make the best choice, considering the advantages offered by air bending, such as a lower bending force and the bending of high-thickness plates.


Coining uses a punch that completely presses the plate, reaching the hollow bottom of the lower die. The die and the punch must have the same inclination angle because this will completely eliminate the spring back.

This system is preferably used for 90° bending of low-thickness plates.  This technology guarantees higher precision and lower angles compared to air bending.


Flattening includes two steps: the first step is pre-bending between 26° and 35° (with air bending). The second step is a partial or total compressing of the plate. This guarantees rigidity, edge protection and no free corners.
