The common plate flange machine is a specialized equipment for forming flanges at the connection ports of the air duct's own plate. The common plate flange system is one of the international systems with a large number of flange connections for wind pipe production, which is convenient and particularly suitable for the production of air ducts with small cross-sectional areas. The common plate flange system can be used for large-scale industrial production and is an efficient duct flange system. Has good rigidity and stability, and has a beautiful and smooth shape during motion molding. Combined with reinforcement machines, shearing machines, and flange folding machines, a simple fully automatic air duct production line can be formed. The machine has a rigorous structure and good performance, saving customers costs and reducing expenses. It is an excellent choice for small-scale production customers.

The common plate flange machine is a specialized equipment for flange forming at the connection port of the air duct's own plate. The common plate flange system is one of the two major systems for producing flange connections for international wind pipes. It has the characteristics of low cost, good sealing performance, and simple and convenient installation, and is particularly suitable for the production and manufacturing of air pipes with small cross-sectional areas. The common plate flange system can be used for large-scale industrial production and is a high-efficiency duct flange system. A fully automatic air duct production line can be formed by combining a common flange machine with a biting machine, a reinforcing machine, a shearing machine, a folding machine, etc.
