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.
Circle angle iron forming machine employs coil to form angle iron flange then cut off the processed work pieces with pleasant appearance and accurate dimensions. The equipment has advantage of compact structure and easy operation.Angle iron punching machine can be matched with the angle iron forming machine to produce perfect circle angle iron.
The 3-roller bending machine features the diamond structure and is used for thicker sheets. The upper roller can be lifted to facilitate plate removal.It is cut into two kinds:symmetric and asymmetric.
With vertical structure, angle iron bender can bend various inner and outer angle iron. It also can roll round steel, round pipe,square pipe, U steel by changing rolling wheels. It is an ideal equipment for bending angle iron flange and section bars and widely used in construction, decoration, hardware, light industry, and chemical industries, etc.
Spiral elbow making machine is of electric and hydraulic type, both of which have two functions: one is used to process single and double hem, and the other is used to press and connect.
Spiral ovalizer is used for the ovalizer duct manufacturing.After spiral duct,the ovalizer duct machine expands it into standard size,with the character of good shape,high efficiency,easy operation.It is indispensable for duct manufacturing.
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.
Duct lock forming machines can process galvanized sheet with different thickness into various shapes,such as profile pittsburgh,single hem,double hem,snap hem,elbow,S shape and so on.
Dcoiler and leveler line is used for different roll bending.It gets a flat plate of requirement width and length after decoil,leveler and cutting.It is combined with feeding shelf,decoiller,leveling,transporter,guiding device set-to- length device,plastic-cover device,shearing machine,transporting table.
Tile rolling forming machine is produced by clients drawing.

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.
