The Cold Forged Round Heat Sink is a high-performance thermal solution designed for efficient heat dissipation in various applications. Utilizing advanced cold forging technology, this heat sink achieves precise straightness and maximized heat dissipation per square millimeter. The process is particularly suitable for forming complex shapes, such as plate-fin, round pin, and oval fin heat sinks. Additionally, cold forging is an ideal manufacturing method for copper heat sinks, as it eliminates the need for high-temperature processing, minimizing material damage and ensuring excellent thermal conductivity.

Winshare Thermal is a pioneer in cold forging technology, with extensive experience in producing both standard and high-power forged heat sinks. Our cold-forged heat sinks are widely used in LED lighting, high-voltage inverters, wind power converters, and motor controllers. By overcoming challenges such as low thermal conductivity in die-cast microchannels and high processing costs, Winshare provides cost-effective and high-performance cooling solutions.
