What is sheet metal bending?

Sheet metal bending refers to the process of turning flat sheet metal into three-dimensional through pressure equipment and special molds, which is called sheet metal bending.

Due to different materials, thicknesses, lengths and widths of plates and different shapes and angles to be formed, there are bending machines with different tonnage and pressure, and upper and lower molds with different heights, shapes and v-openings and special molds with special shapes.
