TDC Machine

Transverse Duct Corner Machine

Liberty TDC flange roll forming machine is mainly for manufacturing connecting flanges used in ventilation ducts. The finished flanges have many features such as high working efficiency, good sealing performance, good connecting results, etc. They are suitable for those ducts with large sections. The TDC flange roll forming machine is comprised of decoiler, main forming unit and cutting system.  We have four models: T-20, T-30, T-35, and T-40

TDC angle - flanged joints requires a ordinary circular saw cut for cutting. Cut two lengths of the flanges 30mm shorter than duct overall dimesion. The flanges should be cut in the direction shown to prevent metal cutting damage on the Cut flanges. If any burring has occurred during cutting of the flange, this must be removed before assembly.

Insert four corners joints into the end of the flange. Please note. Ensure the corners are fully inserted into the flange. Complete the whole frame by securing the corner.


 Install the frame to the duct, should be fairly tapped when inserting from one side of the frame and then along the full length of the flange.


Fix the flange frame on the duct by spot weld or nail. Fixing distance should be according to Standards


When the frame is securely fixed, it is suggested that a duct sealant needs to be applied, on either the inside or outside of the flange and on the corner piece where it meets the duct.
