Manual TDF Folding Machine TDF-1500
Last updated: October 14, 2026
Manual TDF flange folding machine available in 1300/1500/2000/2500mm widths. Precision folding of TDF flanges on duct edges without power — the economical entry into TDF flange fabrication.
Technical Specifications
What is a Manual TDF Folding Machine TDF-1500?
A manual TDF folding machine forms TDF (Transverse Duct Flange) profiles on the edges of rectangular duct panels by hand. The panel edge is progressively folded through the roller or brake action to create the flange that bolts duct sections together with gaskets. Manual models deliver the same flange geometry as powered versions — at the lowest entry cost, for shops whose volume does not justify powered folding.
Key Features
- Folds TDF flanges on duct panel edges without power
- Four widths: 1300, 1500, 2000 and 2500mm
- Bend angle range 0-135 degrees for full flange geometry
- Handles 0.5-1.2mm — the TDF flange gauge range
- 180kg (1500mm) — portable enough to move to the work
TDF Flange Work Without the Budget for a Powered Folder?
Powered TDF folding is fast — but it is a machine, a footprint and a price. Shops doing modest TDF volumes, or starting out in flange fabrication, need the same flange geometry without the investment.
The manual TDF folder folds 0.5-1.2mm panels through 0-135 degrees across four widths — real TDF flanges, hand-powered, at the entry price of the category.
How It Transforms Your Production Line
The Manual TDF Folding Machine TDF-1500 works on a proven principle — here is the step-by-step workflow that makes it possible:
Panel Positioning
The duct panel edge is positioned against the folding line; the target angle is set.
Initial Fold
The leading handle or lever folds the edge through the first stage of the TDF profile.
Progressive Folding
The panel is advanced and folded section by section along its width.
Flange Complete
The finished TDF flange runs the full width of the panel, ready for corner attachment.

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 |
|---|---|
|
✕ Powered folder budget
A powered TDF folder is a large first investment |
✓ Manual folding
Same flange geometry at the entry price |
|
✕ Outsourced flange work
Sending panels out for flanging adds cost and lead time |
✓ In-house folding
Flanging done in your shop, on your schedule |
|
✕ Inconsistent hand folding
Mallet-and-folder flanges vary panel to panel |
✓ Dedicated TDF geometry
Purpose-built folding produces repeatable flanges |
|
✕ Fixed-position machines
Powered folders anchor to one spot |
✓ 180kg portable
Move the folder to the work, not the work to the machine |
Where It Fits in Your Factory
This machine is versatile enough to serve multiple production scenarios. Here are the most common configurations our customers use:
Entry-Level TDF Shops
Real TDF flanges at the lowest cost of entry into flange fabrication.
Low-Volume Flanging
Modest TDF volumes where a powered folder would sit idle.
Portable Flanging
180kg — light enough to reposition as shop layout changes.
Repair & Small Batch
One-off panels and repair flanges made on the spot.
