CNC-Machined Heat Sinks

Our CNC-machined heat sinks redefine thermal management for industries where exact fitment and extreme heat flux are critical. Using advanced 5-axis CNC machining, we create intricate geometries, from micro-fins to integrated mounting systems, that traditional methods cannot achieve.

With in-house CNC capabilities, we deliver functional prototypes in 3-5 days and full production in 2-3 weeks.

Why CNC-Machined Heat Sinks?

✔️ Complex Geometries – Perfect for tight spaces and non-standard component layouts.

✔️ Zero Tooling Costs – Ideal for prototypes and low-to-medium volume orders.

✔️ Material Versatility – Aluminum, copper, or hybrid designs for optimal conductivity-to-weight ratios.

✔️ Rapid Iteration – Modify designs in hours, not weeks.
