Sheet Metal Bending: what you need to know
The best technologies for sheet metal work
Materials for the bent sheet metal:
3 types of sheet metal bending
- The most frequently used mode is definitely the air bending. It uses a punch that presses the metal piece into a V-shaped die below. The bend angle will be determined by the force applied, so it is also possible to bend thick sheets.
- For materials that require, however, a high tonnage load and a more precise angle, we recommend the hollow bottom fold or coining, which is obtained by pressing the part inside the matrix.
- Finally, flattening (or bottom bending) is a type of fold that is mostly used to avoid free edges and obtain more rigidity.

The K Factor
A designer in the industrial sector knows well that in sheet metal bending it is necessary to pay close attention to the K factor, that is what is generally called “springback“. Each material has, in fact, different mechanical properties that come into play when it is deformed. The K factor is the ratio between the thickness of the sheet and the axis of the neutral fiber, or between the distance between the inside of the bend and the neutral plane and its workpiece thickness. While the neutral plane is the area that does not vary during bending, and neither shortens nor lengthens. We can say that the K factor can be summarized as: r / T> 1.
Guide to sheet metal design on the Niuo price estimator
- You can choose 7 different types of steel and 5 different sheet thicknesses.
- Each single piece can be produced if contained within a sheet development with a maximum surface area of 1000 x 1000 mm.
