CNC machined heatsinks
CNC machined heatsinks are milled from solid or plate aluminum for complex geometries, tight tolerances and low-volume runs — including embedded heat pipes and custom interfaces.
When to choose CNC machined
A CNC machined heatsink is the right call when the shape can't be extruded or bonded — curved bases, embedded channels, precise mounting patterns, or low quantities where a die isn't justified. We machine from 6061/6063 plate or from near-net extrusion to save material.
Typical specs
- Tolerance: ±0.01–0.05 mm
- 3/4/5-axis milling
- Embedded heat pipes
- Finish: anodized
Capability
| Parameter | Capability |

| Features | channels, pockets, threads |
| Finish | anodize II/III |
Design tip
- Start from near-net extrusion when volume allows to cut cost.
- Define datum and critical surfaces clearly on the drawing.
