Heatsink Extrusion Profiles for Better Thermal Management
Heatsink Extrusion
Aluminum heat sink extrusions provide excellent heat dissipation. They optimize thermal conductivity for high-power electronics. Available in both standard and custom profiles, these extrusions extend component lifespan by maintaining much lower operating temperatures. They also eliminate the need for bulky, noisy cooling fans. Additionally, these heat sinks fit into tight spaces, making them ideal for LED lighting and power supply applications.
At Conglin, we bring decades of project experience in automotive, aerospace, medical, and solar industries. We deliver customized aluminum extrusions that fulfill your specific performance needs. For high-quality heat extrusions, trust Conglin’s expertise.

Multiple Mold Selection
Aluminum heat sink profiles are produced using different extrusion die structures based on profile geometry and functional needs.
- Solid dies are used for simple fin structures without internal cavities, offering stable extrusion and consistent quality.
- Semi-hollow dies apply to profiles with narrow slots, grooves, or clip features, helping balance metal flow and maintain die strength.
- Hollow dies are required for profiles with internal channels or tubular sections, using ports and welding chambers to form enclosed cavities.
Common heat sink designs include straight fins, serrated fins, round housings with external fins, and profiles with integrated mounting slots, each requiring precise die design to ensure uniform fins and reliable thermal performance.
