The TDF Flange Forming Machine is a special equipment for forming flanges on the connection ports of the air duct itself. The common plate flange system can be used in large-scale industrial production and is an efficient air duct flange system. It has good rigidity and stability, and the shape of kinematic molding is beautiful and flat. Combined with beading machine, shearing machine, common plate flange folding machine, etc., a simple automatic air duct production line can be formed. The machine has a rigorous structure and good performance, which saves a lot of cost for customers.
