What is the difference between the Super Line 5 (AML-6) and the U-shape Line 5 (AML-5U)?

Both produce complete rectangular duct. The AML-6 integrates all functions into one machine — the most compact option, built for small and medium shops. The AML-5U uses a U-shaped multi-station layout for shops that prefer station-based flow. The right choice depends on your floor plan and maintenance preference; our engineers will lay out both options against your building.

What functions does the AML-6 include?

Beading, notching, shearing, Pittsburgh lock forming (movable type), duplex TDF flange forming, duplex angle steel flange forming and folding — the complete rectangular duct process, plus servo feeding, all under one computer control system.

How much coil can it hold?

Four electric coil cradles with four material trays, taking 5-7 tonnes per roll — enough coil capacity to run production without constant coil changes.

What are the dimensions and power?

AML-6-1300 measures 5600×3600×1650mm at 13kW and 4 tonnes; the 1500 and 1600 models run 15kW at 4.5-5 tonnes. Working speed is 16 m/min in 0.45-1.5mm material.

Is the AML-6 suitable for high-volume production?

It is designed for small and medium duct shops needing full-process capability in one machine. For very high-volume production, a conventional straight Line 5 with dedicated stations may deliver more throughput per shift — our engineers compare the two against your target output.

What is a Super Auto Duct Line 5 AML-6?

The Super Auto Duct Line 5 (AML-6), also called the Mini Auto Duct Line 5, packs the complete duct production process into one machine: beading, notching, shearing, Pittsburgh lock forming, duplex TDF flange forming, folding and shearing. It is the economical, space-saving answer for small and medium duct shops that need full-line output without full-line floor space.

Key Features

All functions in one machine: beading, notching, shearing, Pittsburgh, duplex TDF flange forming, folding and shearing
Four electric coil cradles, 4 material trays (5-7t per roll)
Movable type lock forming machine plus duplex TDF and angle steel flange formers
Servo feeding platform and hydraulic folding machine
Computer controlling system throughout
Economical and space-saving — built for small and medium duct shops

Full Duct Process Needed, but a Conventional Line 5 Will Not Fit?

A conventional Line 5 is a train of separate stations — lockformer here, flange former there, folding station at the end — and the floor plan grows with every station you add.

The AML-6 integrates the whole process into one machine: coil cradles, host, movable lockformer, duplex TDF and angle steel flange formers, servo feeding and hydraulic folding, all under one computer control system. Full process, one machine, compact footprint.

How It Transforms Your Production Line

The Super Auto Duct Line 5 AML-6 works on a proven principle — here is the step-by-step workflow that makes it possible:

Coil Loading

Four electric coil cradles with four material trays (5-7t per roll) feed the line continuously.

Forming Functions

The host performs beading, notching and shearing as the strip runs.

Lock & Flange Forming

The movable type lock forming machine, duplex TDF flange former and duplex angle steel flange former run in sequence.

Folding & Output

The servo feeding platform and hydraulic folding machine complete the section — coil to finished duct in one machine.

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
✕ Multi-station footprint A conventional Line 5 spreads across the whole shop	✓ All-in-one machine Complete process in one compact machine
✕ Material handling between stations Every station transfer is handling and delay	✓ Integrated stations Continuous flow inside one machine
✕ Small shops priced out Full Line 5 lines are built for large plants	✓ Economical configuration Full process sized for small and medium shops
✕ Complex line control Many stations, many controls to coordinate	✓ One control system Computer controlling system runs the whole process
