Automatic 7-Line Duct Production Machine adopts a U-shaped structure design, capable of producing rectangular air ducts of various specifications with significantly improved production efficiency compared with traditional equipment. 

        It is compatible with 0.5-1.2mm galvanized steel and 0.5-1.0mm 304 stainless steel plates, with a dimensional precision of ±0.5mm and a maximum processing speed of 10m/min, supporting 1300/1500mm plate widths. 

      It can integrate single-angle locking, common plate flange, edge folding and other processes in one, and punch 9-15° dovetail slots, suitable for processing 0.5-1.5mm galvanized steel and 304 stainless steel plates. Equipped with a fully automatic feeding system, it realizes the whole-process automation of duct production with stable performance and complete functions.
