TDF flange making machine, mainly used for making flange at edge of plate for further joint, is also among basic equipment for modern duct forming line. All bearings of TDF flange making machine used are ball bearings rather than traditional needle bearings, so the TDF flange makingmachine is more durable. The flange shape made by the TDF flange making machine is nice and practical, which makes it a perfect part of duct forming line.
