Square Duct Machine Description of square duct machine:
We have different automatic air duct production lines for producing square / rectangular ventilation ducts. For example, auto duct line II, auto duct line III, auto duct line IV, auto duct line V and auto duct line VI and VII. Different lines have different configurations.

II Square duct machine - auto duct line III:
This consists of electric decoilers, leveling & grooving device, hydraulic notching & punching device, hydraulic shearer and hydraulic folder. The electrical control system uses a computer with a closed-loop servo-system to increase the precision and reliability of the line.
