U-Shape Auto Duct Line 5 AML-5U
Last updated: October 14, 2026
Full U-shape auto duct line 5 (AML-5U) for complete rectangular duct production from coil to finished duct. The U-shape layout saves floor space — ideal for workshops with limited area.
Technical Specifications
What is a U-Shape Auto Duct Line 5 AML-5U?
The U-Shape Auto Duct Line 5 (AML-5U) produces complete rectangular duct from coil to finished section. It integrates coil loading, leveling, grooving, notching, folding and seam closing in a U-shaped floor plan that returns the material flow on itself — delivering full Line 5 capability in roughly the floor space of a shorter line.
Key Features
- Complete process: coil loading, leveling, grooving, notching, folding and seam closing
- U-shape layout saves floor space — fits workshops Line 5 straight cannot
- Electric decoilers with independent frequency-controlled motors
- Mitsubishi computer control system with Siemens electrics
- Hydraulic folding station and inline seam closing option
- Coil to finished duct in one continuous line
Need Full Line 5 Output but Your Shop Will Not Fit a Straight Line?
A straight Line 5 is a long machine — the material runs the full length of your building. Shops in leased units, narrow bays or shared buildings simply do not have the run.
The AML-5U folds the same complete process into a U: coil in one end, finished duct out the other, full Line 5 capability in a fraction of the length.
How It Transforms Your Production Line
The U-Shape Auto Duct Line 5 AML-5U works on a proven principle — here is the step-by-step workflow that makes it possible:
Coil Loading
Electric decoilers with independent frequency-controlled motors feed strip at constant tension.
Leveling, Grooving & Notching
The multi-functional main body levels, beads and notches (sharp and TDF) as the strip runs.
Hydraulic Folding
The hydraulic folding station folds the notched blank into a rectangular duct section automatically.
Seam Closing & Output
The inline seam closing option closes the seam; finished duct sections discharge complete — coil to duct in one line.

Problems Solved: Before vs. After
We asked HVAC fabricators about their biggest production headaches. Here is how this machine directly addresses each one:
| Without This Machine | With This Machine |
|---|---|
|
✕ Straight line too long
A straight Line 5 needs floor space the shop does not have |
✓ U-shape layout
Full Line 5 process in a compact footprint |
|
✕ Manual seam closing
Folded sections queue at the hand closer |
✓ Inline seam closing option
Seam closing runs with the line |
|
✕ Multiple operators
Separate stations mean separate people |
✓ Integrated line
One line, one flow, minimal operators |
|
✕ Inconsistent finished duct
Hand-folded, hand-closed sections vary |
✓ In-line process
Repeatable finished duct from coil to section |
Where It Fits in Your Factory
