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.
Rotary machine used specialized rolling wheels to process the mental sheets into different shapes covering grooving,envelope line,flattening,cutting ,embossing and round elbow.
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.
The HVAC plasma cutting machine mainly consists of a main unit system and its supporting software system. The electrical control system is computer-controlled and equipped with advanced cutting software, and is commonly used for sealing various types of ducts.
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 basic production process is as follows: The metal sheet passes through the positioning blocks and enters the inlet. The first feeding roller group transports the metal sheet and delivers it to the second feeding roller group. Between the two sets of rollers, rotating blades cut the metal edges into the predetermined groove dimensions. Subsequently, the metal is sent to two pairs of rib pressing rollers, forming two flanges. Then, the metal sheet is fed forward and sent to the bending rollers to achieve a round shape.
