Key Features
- Thin-wall tube bent without wrinkling
- True S shape follows the drawing board
- Flared ends accept brass fittings
- Pressure-ready joints for refrigerant
What Ruins a Bent Copper Refrigerant Line?
Short answer: Wrinkles and ovality. This video shows 6mm T2 copper tube swept into S-bends on a CNC machine with close mandrel support - then the ends are flared and fittings added for pressure-tight lines.
What the Video Demonstrates
| Step | Operation | Result |
|---|---|---|
| 1 | Tube on bend die | Supported wall |
| 2 | S sweeps | Round section |
| 3 | Ends flared | Fitting-ready |
| 4 | Sets bundled | Install-ready |
Key Applications
- Air-conditioner and refrigeration lines
- Heat-pump connection tubing
- Hydraulic and pneumatic copper runs
Why Mandrel Bending for Thin Tube
| Empty-hand bend | Mandrel CNC (shown) |
|---|---|
| Wall crumples outside | Section stays round |
| Flow restriction | Full bore kept |
FAQ
Can you bend aluminum tube too? Yes - same machines, different dies.
Do you supply the fittings? Brass flare fittings are assembled in the same shop.
