HVAC machine 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 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.

Besides the advantages of spiral tube machine, Al foil tube machine also features good retractility and incurvating capability. It suits in ventilation systems as low demand on installation with much bending paths, such as kitchen, toilet.

The spiral air duct machine is divided into molding type of rolling cutting and steel strip of saw cutting. The molding of corresponding size must be used for each size of spiral air pipe. For the steel strip type,adopt different specifications and lengths of steel strip, can process the corresponding size of air duct.

Angle iron flange punching and cutting including total 5 parts: Feeding device, major part, cutting device, hydraulic and electric system. PLC control system can improve accuracy , more effective and lower cost.

Lock formiing machines,as one of our flagship products,including representative LC-10,LC-12 and LC-15 series,can process galvanized sheet with different thickness intovarious shapes.Normal lock formers can process galvanized sheet with thickness in the range of 0.5-1.5mm,at most 2.0mm.LC-12DR and LC-15DR can process 6 kinds of profiles. If customers need, we can design special machines to make special profiles.The machine features in light weight,so it is easy to move and suitable to be used at sites.

With the advantages of reasonable design and structure, high precision and  efficiency, flexible adjustment and convenience. Function: automatic detection coil parameters, decoiler and feeding with one key, automatic adjustment Automatic switching, automatic detection and calculation with safe and reliable
