Folded Fin Heat Sinks

Folded fin heat sinks are advanced thermal solutions created by folding thin metal sheets into tightly packed, accordion-like fin arrays. This design maximizes surface area while maintaining a compact footprint, making them ideal for applications where space, weight, and heat density are critical constraints.

Our proprietary Manufacturing Process enables micron-level precision in fin folding, achieving 40% higher surface density than stamped alternatives. Prototypes delivered in 5-7 days with thermal validation reports.

Why Choose Folded Fin Designs?

✔️Space Efficiency – Ideal for densely packed electronics (e.g., avionics, servers).

✔️Weight Reduction – 30% lighter than solid machined fins with equivalent performance.

✔️Customizability – Adaptable to curved surfaces or irregular layouts.
