Aluminum Skiving Fin Heatsink

KINGKA Tech Industrial Limited, founded in 2010, is a professional manufacturer specializing in aluminum alloy thermal solutions. Our main products include high-performance Heat Sinks and Liquid Cold Plates, designed to meet the most demanding thermal management requirements in industries such as telecom, aerospace, automotive, industrial control, power electronics, medical instruments, security electronics, LED lighting, and multimedia/consumer applications.

The Aluminum Skiving Fin Heat Sink is an advanced cooling component produced by a high-precision skiving process, which slices ultra-thin fins directly from a solid aluminum or copper block. This technique ensures excellent thermal conductivity, high fin density, and superior heat dissipation performance compared with traditional heat sink extrusion or die-cast methods. It is widely used where compact size, high efficiency, and lightweight design are essential.
