Hydraulic Duct Elbow Machine

Elbow is a common structure in HVAC duct making areas, being used for corners and turnings, connecting the ducts adapting to the special building structure. Our hydraulic elbow making machine makes it much easier to form the elbow. And the traditional manual work is heavy and noisy.

High production Gorelocker produces standing lock seam elbows and reducers. The high flexibility is achieved by means of 2 separate workstations: a flanging station and seam closing station. Thus the machine is always ready for operation without time-consuming conversion. The standing seam reduces welding to just one longitudinal seam and improves rigidity.

As a fabricator, making duct for others, this kind of hydraulic elbow maker is the best option. It provides a faster process: not having to change dies from Gore Flanging to Gore Connecting– a significant time savings. The diameter range is from 125mm to 1250mm, Galvanized steel thickness: 0.4~1.5mm.
