F. Other specific Features of Comifo Coil Line:
1) Formula Programme, which insure setting and producing different materials with different sizes, different quantities in one time.
2) Coil Draw Back, draw back coil is not needed; Comifo coil line can draw back the coil automatically for further production, which saves time and no waste materail.

G. Duct auto lines are Comifo's star products.
