The bending of sheet metal
In sheet metal working, the bending of sheet metal is still a very widespread process, even if it presents some very practical difficulties linked to the nature of the material itself.
It is a process that makes it possible to shape the material in many different ways, bringing artefacts of all kinds to life. It is a plastic deformation process, carried out using machinery that presses and folds the piece being worked.
Thanks to the use of the latest equipment and the development of increasingly sophisticated technology, it is now possible to control the behaviour of materials during deformation much more accurately, with greater precision of the folding angle.
Someca has a wide range of tools to make multiple types of folds, and we use “ad hoc” folding moulds when required to meet the specific needs of the customer. We use the air bending technique using an upper punch that presses the sheet into a V-shaped die. In this process, the sheet has three points of contact with the machine: one on the upper punch and two on the die.
The main advantages of this technique are the reduced force needed to bend the sheet compared to other processes and the possibility of creating more extreme angles. Someca is equipped to carry out machining on different types of materials, including carbon steel, and all its derivations, stainless steel, especially AISI 304 and 316, and aluminium and its various alloys.
