This equipment is a high‑efficiency sheet‑metal forming system specially designed for manufacturing body panels of buses, trucks, rail‑transit vehicles, and special engineering vehicles. Using a continuous cold‑roll‑forming process, it converts metal coils in a single pass into body‑panel components—such as side panels, roof panels, and floor panels—featuring reinforcing ribs, corrugations, or special cross‑sections. With high forming accuracy, excellent production efficiency, high material utilization, and consistent strength, it is suitable for large‑scale, standardized production of vehicle body panels.
