u shape auto duct production line 6s

The GZHCH Automatic CNC Duct Production Line is our latest Duct coil line machine. With U-type structure, it reduces time of plate passing period which achieves the productivity of 20-25 seconds per piece. Pittsburgh Seam and Single Seam forming separately by Two Lock Forming Machine which makes the Pittsburgh Seam after processing is in the front. When producing large-size duct, the short side bent first, which is more suitable for the Duct Seam Closing and Heavy Gauge Material.
