RECOMMENDED PRODUCTS
Also known as Lock Former or Pittsburgh Seamer, it's a multi-functional machine for varying uses in the HVAC ducting industry. Designed for the formation of different types of seams, which are used in the manufacture of rectangular and round ducts, chimneys, gutters. The rolls are made from the highest quality case-hardened steel and can be easily changed.
GZHCH Automatic CNC Duct Production Line is our latest coil line. With U-shaped structure, it reduces time of plate passing period which achieves the productivity of 20-25 seconds per piece. The design adopts the Duct Line III as the main brain, 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 seam closing.
