Air duct production line  Ⅷ is a new type of air duct automatic production line of our company. The U-shaped structure not only saves the production site, but also reduces the delivery time of raw materials. The production efficiency is high (about 20-23 seconds per piece). The department fully automatically realizes the fixed size cutting, beading, automatic cutting ,the notching, single hem forming, pittsburgh forming, TDF flange and the angle iron flange ,automatically forming and bent into ”L“, ”U“, ”口“ shaped duct. Equipped with punching support air, TDF flange hole is optional. Pittsburgh is formed before bending the short side of the large size duct. It has the advantages of high automation, high efficiency, labor saving and material saving.

HVAC duct line  Ⅶ ,with U-shaped structure not only saves the production site, but also reduces the delivery time of raw materials. The production efficiency is high (about 20-23 seconds per piece). The department fully automatically realizes the fixed size cutting, beading, automatic cutting ,the notching, single hem folding, pittsburgh forming, TDF flange and the angle iron flange ,automatically forming and bent into ”L“, ”U“, ”口“ shaped duct. Equipped with punching support air, TDF flange hole is optional. Pittsburgh is formed before bending the short side of the large size duct.C+S flange is optional.It has the advantages of high automation, high efficiency, labor saving and material saving.

HVAC duct line VI,the U-shaped structure not only saves the production site, but also reduces the delivery time of raw materials. The production efficiency is high (about 20-23 seconds per piece). The department fully automatically realizes the fixed size cutting, beading, automatic cutting ,the notching,pittsburgh forming, TDF flange and the angle iron flange ,automatically forming and bent into ”L“, ”U“, ”口“ shaped duct. Equipped with punching support air, common plate flange hole is optional.It has the advantages of high automation, high efficiency, labor saving and material saving.

Ventilation duct machine The air duct production line V is composed of feeding frame, leveling and beading, hydraulic punching point and square mouth, hydraulic shearer, movable pittsburgh forming machine,feeding platform, duplex flange machine, duplex angle iron flange machine (or double snap lock machine), servo feeding platform and TDF hydraulic folding. The computer control part adopts full computer control, bending with servo feeding, accurate positioning, especially when processing the bigger air duct, to ensure the bending accuracy.

HVAC duct fabrication machine Ⅲ features in high auomation,high efficiency and saving materials,which is very suitable for mass production of square ducts. Autoline - III consists of a metal feeding frame, leveling and grooving equipment, hydraulic punching square notch equipment, hydraulic cutter and folder. The electrical control system uses a computer with a closed-loop and servo-system to increase the precision and reliability of the manufacture line. The maximum working speed is 16m/min.The length tolerance is±0.3mm. The diagonal line tolerance is ±0.5mm.   One team will produce 1000㎡of square duct by using this system.

Air Duct Machine Line Ⅱ is mainly for TDF flange blanking,meanwhile,it can be used for normal sheet blanking.Matched with TDF forming machine,pittsburgh lock former,folder and angle joint joint,the line can produce nice TDF ducts.
