HVAC Air Pipe Production Line
Air Duct Wind Tower Production Line
Rectangle Air Duct Production Line
Duct manufacture auto line is designed for large volume workshops and is used to work with the coiled metal with weighting up to 6 tons, thickness up to 1,2 mm and minimal duct size 160x160 mm.
The machine provides high efficiency production of straights air-ducts. The production process can be managed by only one operator. The quantity and the parameters of the required products are inserted directly through the Touch Screen of the controller with a convenient and easy to manage interface.
Duct manufacture auto line has a modular design which allows to use it in different configurations: feeding & straightening of the coiled metal, bending, punching, cutting-to-length, Pittsburgh forming, TDF flange, “C” flange, angle iron flange forming, duct folding and closing
