Sheet Metal Bending: Basics, Types, and Tips for …

Product Details: The sheet metal bending process involves applying a force to a sheet metal part to change its geometry and physically deform without breaking. This force causes stress on the sheet metal beyond its yield strength, causing the material to physically deform without breaking or failing. The process typically uses machines like press brakes, which work by lowering a punch onto a sheet metal positioned on a die, creating the desired geometry. There are several sheet metal bending methods, including V-bending, bottoming, wipe bending, roll bending, and rotary draw bending.
