Bending is a manufacturing method used to reshape materials by applying force to make them conform to a desired angle or shape. It is commonly used with metals, plastics, and other materials. The thickness of the material being bent depends on its type and strength. For example, thin sheet metals can be easily bent, while thicker metals may require specialized machinery or techniques. Typical thicknesses for bending can range from a fraction of a millimeter for thin sheets to several centimeters for certain metals, providing flexibility to create curved or angular components for various applications.
