Duct Production Line 3 is a highly integrated automatic duct manufacturing system designed for efficient production of rectangular HVAC ducts.
It combines decoiling, leveling, beading, cutting and flange forming into one continuous production line, significantly improving productivity while reducing labor cost.


High efficiency solution for rectangular duct fabrication
Fully automatic production
Integrated coil to duct system
Stable performance & high precision
Duct Production Line 3 is designed for medium to large-scale duct production, offering stable performance, high forming accuracy and consistent product quality.
With PLC intelligent control, the whole line runs automatically from metal coil feeding to finished duct sheet output.
Continuous automatic production significantly increases output and reduces production time.
Precision leveling and forming systems guarantee uniform duct size and high surface quality.
PLC control system with touch screen interface allows easy operation and quick setup.
Only 1–2 operators are required to run the entire production line.
Heavy-duty machine frame ensures long service life and stable operation.
Duct Production Line 3 is widely used in:
HVAC duct manufacturing
Commercial building ventilation systems
Industrial ventilation projects
Tunnel and metro ventilation
Hospital and clean room air systems
High level of automation
Stable and reliable performance
Flexible configuration options
Suitable for mass production
Professional technical support and after-sales service
