Manufacturing Process

• Extrusion: Most heatsinks are made via aluminum extrusion, allowing cost-effective mass production.

• CNC Machining: Used for high-precision heatsinks with tight tolerances.

• Die-Casting: For more complex, non-extrudable shapes.

• Bonding & Skiving: Used for ultra-thin fins in high-performance cooling.

Surface Treatments

• Anodizing (Black/Color): Improves corrosion resistance and emissivity (heat radiation).

• Powder Coating: Adds protection and aesthetic appeal (less common for high-performance heatsinks).

• Bare Aluminum: Sometimes used for cost-sensitive applications.

Common Applications

• Electronics Cooling: CPUs, GPUs, power transistors.

• LED Lighting: Keeps LED junctions cool for longer lifespan.

• Power Electronics: IGBTs, inverters, motor drives.

• Automotive & Aerospace: Battery cooling, power electronics.
