The duct line Ⅴ adds a bending machine that is not found on duct line IV. The end product is almost a fully rectangular duct that can be used immediately after the edges have been sealed with a seam closer and corners have been inserted.

The production line is fully automated, which saves labor and increases both the precision and productivity. The duct line V features a prefill angle flange former or a TDF flange former, both of which are easily interchangeable and easy to operate.

Duct line Ⅴ consists of the material compartment, flange former, duct beader, sheet shearing machine, and angle pressing machine.
