Work Flow:


Note：
1. Cut to length or cut blank for plasma cutting machine
2.1 Punching and notching for “C” “S” cleat duct. It can cut different types of notches such as ”L”, “U” and “口”. It can also cut blank for “C” and “S” cleat flange machine.
2.2 Manufacture TDF flange duct automatically.
2.3 Cutting blank for angle iron flange or “Z” shape flange machine.Used with a vertical seaming machine to get a full wrap duct.
3. Cutting blank for TTF/LT mate flange. Used with a vertical seaming machineand mate flange machine to get a full wrap duct.
