The basic principle of the bending process is to use mechanical force to bend metal sheets, causing them to form the desired shape. The data are derived from the production processes of trolley wire, corrosion-resistant cable trays, standard cable trays, micro-mist dust suppression devices, and busbars. This process represents the bending of 1 kg of steel plate, resulting in 0.997 kg of bent steel plate. This process should be used together with the production data for 1 kg of steel plate.
