Square Duct Auto Production Line IV (DML-VI, 1250/1550mm, 16m/min) | DDM Machinery, Shanghai, China
Square Duct Auto Production Line IV (DML-VI-1250 / DML-VI-1550)
DDM Machinery: Shanghai, China
Servo-controlled rectangular HVAC duct line from coil to finished duct, handling 0.5 to 1.2mm sheet up to 1,550mm wide with automatic notching, cutting, flanging, and folding, and length tolerance of ±0.5mm.
The Square Duct Auto Production Line IV is a complete line for making rectangular HVAC duct from coil. The line consists of a decoiler, a leveller and grooving unit, "V" and square notching units, a cutting unit, a bending unit, a reciprocating lock former, a feeding unit, and duplex flange forming units for both TDF and angle-iron flanges. A servo system controls the whole production process.
DDM says the line has a small footprint for its output, low energy consumption, and is easy to move, and that it can produce a wide variety of rectangular ducts. It has its own separate console, and a closed-loop feedback system that DDM says greatly improves accuracy and stability. The stated accuracy is ±0.5mm on length and ±0.8mm on the diagonal.
The control components are branded: a Mitsubishi HMI display and PLC, Mitsubishi frequency converter, a Japanese Nemicon inverter, a Taiwanese Hydromax pump, and Taiwanese high-temperature resistant tubing.
Why Choose an Automatic Duct Line?
Rectangular duct involves many steps: cutting the blank, notching the corners, forming the seams, folding, and making flanges. On a manual setup each step needs a machine and an operator. An automatic line does them in one pass and holds tight tolerances.
- Tight tolerances. ±0.5mm length and ±0.8mm diagonal.
- Both flange types. Duplex forming for TDF and angle-iron flanges.
- Fewer operators. Servo control across the whole process.
- Reliable components. Mitsubishi PLC and HMI, and Mitsubishi frequency converter.
- Two widths. 1,250mm and 1,550mm maximum sheet width.

Frequently Asked Questions
What thickness and width of sheet can it handle?
0.5 to 1.2mm, in maximum widths of 1,250mm (DML-VI-1250) or 1,550mm (DML-VI-1550).
How accurate is it?
DDM states ±0.5mm on length and ±0.8mm on the diagonal.
What flange types does it make?
TDF flanges and angle-iron flanges, with duplex forming machines for each.
How fast does it run?
Up to 16m/min (see notes).
How much space does it need?
About 18m long by 3.4 to 3.6m wide.
What controls does it use?
A Mitsubishi HMI and PLC, with a servo system and closed-loop feedback.
Does DDM make other duct lines?
Yes. DDM lists Square Duct Auto Production Lines II, III, and V.
Is financing or staged payment available?
Yes. A deposit secures your order and begins production, with the remaining balance due only once your machine has been built, inspected, and is ready to ship.
Should I buy new or used?
These lines are available new, built to order.
