Bending Sheet Metal Around Corners

The solution is to have a radius on the tool that you ll be using to bend the metal.

Bending sheet metal around corners.

Bending a brittle metal beyond its limits could cause the metal to snap and break. Commonly used equipment include box and pan brakes brake presses and other specialized machine presses. Bending is a manufacturing process that produces a v shape u shape or channel shape along a straight axis in ductile materials most commonly sheet metal. As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be.

The slack between the wipe die and the punch plays an important role in getting a good result. As a result the wipe die also determines the bend s inner radius. A short video showing how to bend an outside corner demonstrated on a pro series metal bending machine but applicable to most machines. It is important to make sure that the sheet is properly pushed onto the wipe die.

Typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork. If you bend to a sharp inside corner with sheet metal you ll be adding a ton of internal stresses. Even on malleable materials you can end up cracking the metal at the bend or weakening it to the point where it ll break with minimal force. Find metal siding trim at lowe s today.
