Rubber pad forming is a metal forming process in which a rubber pad is inserted between the tool and the workpiece. This process is used to form complex parts such as panels, aircraft skins, and automotive body panels. The rubber pad absorbs shock, allowing the tool to make tighter bends and sharper angles, while minimizing tool and workpiece deformation. The rubber pad also helps to reduce noise and vibration, making the process more efficient and less time-consuming.
