The LFB-1500 spiral duct end flanging machine is a round duct processing device used for flanging the ends of round air ducts. It is specifically designed to bend the edges of long duct pipes so they can be connected to flanges. The duct fabrication machine enables fully automatic flanging operation, requires low operator skill, is easy to learn, and can quickly bend the duct ends into a neat, uniform, and smooth flange. This significantly improves the assembly efficiency and connection quality between the duct and the flange.

This spiral duct end flanging machine achieves fully automatic flanging operation, simple to use, requires low personnel skill, and is easy to master.

Flange size is accurate (10-20mm), with smooth and uniform forming, free from distortion or cracks, effectively ensuring the sealing and firmness of the duct-to-flange connection.

The LFB-1500 spiral duct end flanging machine is primarily used for flanging the ends of round air ducts (200-1500mm) for easy connection to angle steel flanges, TDC/TDF flanges (co-plate flanges), etc. It is widely applicable in ventilation duct factories and sheet metal processing workshops for standardized, high-volume production of duct ends.
