T Duct Line 4 processes metal sheets with a thickness of 0.5-1.2mm (maximum width 1500mm). It integrates integrated functions including uncoiling, leveling, beading, punching, locking, and flange forming, effectively resolving material jamming issues and reducing the need for heavy maintenance. Its 3-line bending design saves raw material; meanwhile, the bearing steel reels boast a 5-times longer service life. Equipped with CNC automatic material withdrawal and production memory functions, the line features a compact structure, easy operation, and is ideal for duct manufacturing.

The Super Auto Duct Line 5 realizes full automation of duct production, covering core processes including coiling, leveling, locking, flanging, and folding. Equipped with precise servo feeding technology, it performs exceptionally well in square duct manufacturing—while also saving raw material. The line operates stably via a 10-inch touchscreen, and a single operator can achieve high production output.
