Let's show you how to make TDF Duct by automatic operation

Advantages of spiral ducts

1 Good product matching and high degree of standardization; 2 Strong airtightness; 3 Low ventilation loss; Low ventilation noise, round tubes are better than square tubes. 4 Convenient factory inspection; 5 Material saving; 6 Convenient installation, few connection points, small installation space, and low installation cost. 7 The overall installation layout is beautiful and high-grade. 8 Convenient daily maintenance and cleaning. 9 Small cross-section wet perimeter, small resistance along the way, and smaller energy loss. 10 Fully machined, one-time molding without secondary processing. 11 High-speed flying cutting machine is used, and the pipe diameter accuracy is high. 12 Four methods are used: reducing sleeve connection, sleeve connection, flange connection, and belt connection, which makes installation more convenient. 13 The quality of external insulation of the pipe is better than that of rectangular ducts.

About TDF Flange Machine

The TDF Flange Machine is a special equipment for forming the flange on the plate connection port of the air duct itself. The common plate flange system is one of the two major flange connection systems for air duct production in the world. It has the characteristics of low cost, good sealing performance, simple and convenient installation, and is especially suitable for the production of air ducts with small cross-sectional areas. The common plate flange system can be used in large-scale industrial production and is a high-efficiency air duct flange system. The combination of the common plate flange machine and the seaming machine, the beading machine, the shearing machine, the folding machine, etc. can form a fully automatic air duct production line.
