The vertical ram of these press brakes drives a punch into a die to form a crease in sheet metal. They accommodate larger sheets than horizontal press brakes and provide more control of bend profiles than straight or box-and-pan brakes. The sheet metal workpiece sits on top of the die along the selected fold and the brake lowers the punch into the sheet, forcing it into the die to make the fold. Press brakes are commonly used to bend automotive panels, create metal containers, and form framing components.
