Duct Manufacture Auto-line Ⅳ

Rectangular Duct manufacture auto line Ⅳ for the Manufacture of Air-condition Rectangular Ducts

Rectangular Duct Forming Machine or duct manufacture auto coil line Ⅳ is designed according to the customer’s request and advice, then manufacture the new one machine after our engineer’s studying the ducting standard of the domestic and foreign, Line combines a feeding metal frame, leveler grooving roll, hydraulic notch and punch square machine, hydraulic shear, movable pittsburgh lock machine, duplex trans-verse flange manufacturing machine, TDF hydraulic folder and CNC system. Is efficient, saves work area by inline positioning of machines.
It’s a new one completely in the present market, with full functions, working stable and automatic control system.
The following is the shape of flange, we can design the just shape according to customer’s request.

Duct manufacture auto line Ⅳ Advantage

All the duct processing can be completed with this line.
The efficient will be 3—6 times than the normally line, can reduce 5-8 operators, and reducing the raw material cost.
Low cost: this line can check head material and the tail material automatically, and calculate the left material,
Multi-purpose: Slitting the sheets, product the sheets, “ ”,“ ”,“ ” of duct with the flange or without.
United lock-seam pre made.
Simple operating, only need to input the duct type, size and quantity, all operation will be controlled automatically.
Material Range: Galvanized sheet 0.4-1.2mm, width: 1300mm.
High efficiency: 0-18 m/min.
Smaller working area requirement, 15mx4m.
Convenient moving designing: overall designing, adopt the standard connecter, suit for machine movement.
With the world famous brand electrical components to achieve the Stable quality.
