Tuling Folded Fin Heat Sink
Tuling folded fin heat sinks are corrosion-resistant, stress-resistant and thermally conductive. We utilize progressive die stamping to produce the folded fins. Later, we use soldering or dip-brazing technology to connect the fins to the base.
Our complex folded fin heat sinks can be of different types: round crest, plain flat crest, semi-flat crest, louvered, lanced and offset, wavy, and ruffled. The large surface area of our heat sinks offers a high thermal performance with increased airflow.
Tuling is ISO 9001:2015 and ISO 14001:2015 certified. All our folded fin heat sinks are CE, ROHS, UL, TUV, and SGS compliant.

Tuling Folded Heat Sink Features
Tuling folded heat sinks have a compact design and take less space.
We can combine aluminum and copper to tailor the heat sink’s efficiency.
With high aspect ratio fins, our heat sinks can dissipate heat more efficiently.
The material and machining cost for manufacturing folded fin heat sinks is low.
Tuling Customizable Folded Fin Heat Sink
At Tuling, we can customize all the geometrical features of a folded heat sink. Dimension specifications of a typical folded heatsink are:
| Fin material thickness | 0.002″ to 0.080″ |
| Fin height | 0.020″ to 4.00″ |
| Fin density | 2 to 86 fins per inch |
| Airflow lengths | up to 24″ |
| Heat sink width | up to 24’’ |
| Heat sink height | up to 6’’ |
| Fin angle with the base | 90° |
Tuling Folded Heat Sink Materials and Finishing
Our folded fin heat sinks are made of aluminum and copper due to their excellent thermal conductivity and ease of fabrication. We allow you to select other conductive metals like stainless steel, copper-nickel alloy, titanium alloy, inconel or other nickel alloy.
Tuling facilitates anodizing, paint coating, and powder coating on the heat sinks for enhanced aesthetics and thermal performance. Non-coated milling, brush, and sandblast finishing are convenient where visual appearance is insignificant.
