Advantages of extruded heat sinks
- The production process of extruded heat sinks is simple, and material costs are relatively low.
- Extruded heat sinks exhibit excellent thermal performance under medium to high airflow conditions.
- Extruded heat sinks have outstanding surface smoothness and appearance.
- Extruded heat sinks can easily undergo secondary processes such as anodizing, drilling, and welding.
- The cross-sectional design of extruded heat sinks provides omnidirectional heat conduction properties.
Given the comprehensive advantages of extruded heat sinks in terms of molds, performance, and manufacturing costs, we strongly recommend them as your preferred solution for thermal management.Quick Quote
The most cost-effective manufacturing process for extruded heat sinks
- Heating the aluminum billet, which typically has a cylindrical or square shape, with the diameter or side length depending on the final dimensions of the heat sink profile.
- Extruding the billet by applying high pressure to extrude it from the mold, forming the desired shape of the heat sink profile.
- Cutting the extruded heat sink profile to the required length.
- To further enhance the mechanical properties of the heat sink profile, thermal treatment is often applied.
- Anodizing is typically performed to protect the surface of the heat sink profile from corrosion.
- Ensuring that the heat sink profile meets quality standards by conducting rigorous inspections.
