Sinoextrud: Your Aluminum Heat Sink Manufacturer
Aluminum Heat Sinks are essential for passive thermal management in high-power electronics and mechanical systems. Their lightweight, high-conductivity design allows efficient heat dissipation across a wide range of devices.
We manufacture customized heat sinks using extrusion, CNC machining, and skiving technologies to support applications in LED lighting, communication base stations, solar inverters, and electric vehicle systems.
Our range of surface finishes improves both corrosion resistance and thermal emissivity. Black anodizing is especially effective in enhancing heat radiation, while clear finishes preserve conductivity where grounding is required.
Advanced processing capabilities such as slotting, drilling, and bonding allow seamless integration into your system architecture. We also provide thermal interface material application and component assembly upon request.
With extensive tooling capabilities, stable production lines, and strong R&D support, we deliver high-precision heat sinks for OEMs and industrial clients seeking reliable thermal control solutions.
