Sheet Metal Bending

Bending is a common sheet metal fabrication process which finds use in almost all industries that use sheet metal fabricate parts. Industries that work with sheet metal or use sheet metal parts need bent geometries in one way or the other.

Prolean offers accurate angles with bending services. Our veteran engineers and advanced brakes and presses ensure quality bent parts at your end.

Sheet Metal Bending

Bending is as simple as the name sounds. A machine bends a sheet of metal along a straight axis and creates U, V, or channel shapes. Bending finds use in the manufacturing of casings of electronics, panels for automobiles and airplanes, construction parts and other similar applications in other industries.

How Does Bending Work?

Fabricators use machines called press brakes for sheet metal bending. The process begins by placing the sheet metal on the machine. Once the sheet is in the right position, the machine uses force to bend the metal using mechanical, hydraulic, or pneumatic systems. Due to the elastic nature of metals and stresses in bent sheet metal, when the machine releases a part the bend angle reduces a little due to the springback effect.

The sheet has to be over-bent by a certain angle to account for this effect and achieve accurate angles. The shape of the bend and angle of the bend depend on the material and design. Bending usually doesn’t require any further work after coming out of the machine and the part goes for the next machining process or to an assembly line.


Advantages of Sheet Metal Bending

Rolean’s sheet metal bending services offer the most accurate angles and best part quality. With our modern brake presses and experienced engineers, the results are always close to perfect.

Our broad range of materials allows you to choose quality sheet metals that work best for your applications and have strength to take the application loads. We do manufacturability checks and offer design help when required to make sure complex parts have optimum design and efficient production.
