TDC Flange Roll Former

Duct flange roll forming Machine brief introduction
Duct flange Rollforming machine was specially designed to manufacture HVAC flanges of 20 and 30 mm size for medium and large producers of square HVAC duct.
The principal benefit is that it isn’t necessary any more to purchase flanges of 4 – 6 m length and cut them to various lengths. On this machine it is possible to manufacture flanges precisely according to the dimensions of the produced air ducts.
Rollforming machine VS5 consists of several parts. At the beginning, sheet metal is being unwound from the vertical decoiler, then it enters through feeding into the very profiling part. Consequently the flange is straightened and cut into desired number of pieces and of required length by hydraulic shears, precisely according to the parameters entered. Automatic line control system can be connected to central production management as well.
Change of 20-30 or 30-20 flange produced is also very easy, you only need to feed the sheet metal into the left or right part of the machine and switch over the control system.
The line can also be equipped with a device for injection of sealing mastic directly during the forming process.

TDC Flange Roll Former specifications

The TDC flange roll forming machine is for making rectangular duct connectors. Slip on Flange is one of the two universal rectangular duct flange making systems in the world. It can save time and material drastically with its well-seal, strong and durable joint structure. So Slip on Flange Roll Form Machines is much suitable for producing a duct with a large sectional area. Many famous buildings in the world utilize this kind of structure in the ventilation system
Our TDC flange roll former is for manufacturing TDC-20 mm, TDC-30, TDC-40 wide slide on frame flange etc. custom TDC flange profiles can be offered on request. The Slip on Flange lines can also be equipped with a device for injection of sealing mastic directly during the forming process.

TDC Flange Roll Former Machine is consisted of Feeding frame (De-coiler), main forming machine, straightening device, round saw tracing cutting unit, etc.
