Specifiche tecniche
High-Precision Micro-Forming
Achieving a density of 50 FPI requires extreme precision in blade alignment and profile geometry. Nexmek's micro-fin blades are designed with a unique low-drag flank angle that facilitates the flow of aluminum during the rolling process, ensuring sharp, uniform fin tips and consistent root spacing.
- Advanced CNC profile grinding for 0.005mm accuracy
- Optimized for 1060 and 1100 series aluminum
- Prevents tube deformation in high-density sequences
Fin Density & Capacity Standards
Our tooling supports a wide range of micro-fin configurations for various industrial requirements.
| Density (FPI) | Pitch (mm) | Application | Target Industry |
|---|---|---|---|
| 32 FPI | 0.79mm | Residential AC | HVAC-R |
| 40 FPI | 0.63mm | Commercial Cooling | Industrial |
| 50 FPI | 0.50mm | Compact Evaporators | Automotive/EV |
| 60 FPI | 0.42mm | Precision Cryogenics | Aerospace |
Maintaining Tube Structural Integrity
High-density finning can often stress the base material of the tube. Our micro-fin blades are engineered to balance the radial load, ensuring that even when forming 50 fins per inch, the internal wall thickness remains within specification. This is critical for systems using modern high-pressure refrigerants or for aerospace components where reliability is paramount.
