[0002] Vehicle body covering parts refer to the surface or internal parts with a spatial shape made of metal sheets that cover the engine and chassis and form the cab and the vehicle body. They can be divided into three categories: external covering parts, internal covering parts, and skeleton covering parts according to their functions and positions. Stamping is a pressure processing method that applies pressure to materials using a die installed on a press at room temperature to cause separation or plastic deformation, thereby obtaining the required parts.
