TDC Flange Roll Forming machine for the Manufacture of Air-condition Rectangular Ducts Fittings
Duct TDC flange Roll-forming machine was specially designed to manufacture HVAC flanges of 20mm, 30 mm or other size for medium and large producers of square HVAC duct.
Roll-forming machine consists of several parts. At the beginning, sheet metal is being unwound from the vertical de-coiler, 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 round saw style cutter, precisely according to the parameters entered. Automatic line control system can be connected to central production management as well.
