Tips for Bending Sheet Metal – Make It From Metal

Sheet metal is extremely handy for all kinds of jobs since it’s so easy to work with. You can do a lot with only a handful of tools. Even still, it can be pretty easy to mangle if you don’t use the right technique. Here are a few tips that will let you make accurate, clean, and professional-looking bends when you’re working with sheet metal.

Sheet Metal Bending - Manufacturing

Bending of sheet metal is a common and vital process in manufacturing industry. Sheet metal bending is the plastic deformation of the work over an axis, creating a change in the part's geometry. Similar to other metal forming processes, bending changes the shape of the work piece, while the volume of material will remain the same.

Sheet Metal Forming - CustomPart.Net

Sheet metal forming processes are those in which force is applied to a piece of sheet metal to modify its geometry rather than remove any material. The applied force stresses the metal beyond its yield strength, causing the material to plastically deform, but not to fail. By doing so, the sheet can be bent or stretched into a variety of complex shapes.
