TDF flange machine is a special equipment for flange forming on the plate connection port of air duct itself. TDF flange former is one of the systems with a large number of flange connections in air duct manufacturing in the world, which has the characteristics of convenience and is especially suitable for air duct production with small cross-sectional area. The TDF flange can be used in large-scale industrial production, and it is a high-efficiency duct flange system. It has good rigidity and stability, and its shape is beautiful and flat. Combined with the bar press, plate shearing machine, flange folding machine, etc., it can form a simple full-automatic air duct production line. The machine has strict structure and good performance, which saves costs and reduces expenses for customers and is the best choice for small-scale production customers.
