This machine can be formed at the flange (PDF) at the same time continuous rotary riveting. Production speed of 10m /min. only needs to replace the corresponding roll, you can produce the 20mm for your production needs, 30mm or 35mm flange. The flange machine can be single-side or both sides at the same time.

      PDF flange is a better choice than TDC flange, it does not like the TDC flange to the flange according to the specific size of the pipe to cut off the flange, combination, installation, riveting, but the small side of the flange directly to the wall of the duct, reducing the manufacturing cost and improve the work efficiency.
