Product Overview
Engineer superior thermal management with Shenzhen Sunmy Hardware. Our Custom Square Body Heat Sinks are designed for high-power applications requiring exceptional heat dissipation efficiency. Whether for high-lumen LED lighting, industrial power supplies, or CPU cooling, this series combines high-density fin capability with precise geometric stability. Available in both 6000 Series Aluminum Alloy (for lightweight efficiency) and Pure Copper (for maximum thermal conductivity), our heat sinks are manufactured to meet exact client specifications.
Process & Manufacturing Insights: Precision Engineering
At Shenzhen Sunmy Hardware, we utilize advanced manufacturing techniques to overcome the limitations of standard extrusion.
Skived Fin Technology (Micro-Cutting)
Unlike traditional bonded fins, our skiving process carves fins directly from the solid metal block. This creates a one-piece construction with zero thermal resistance between the base and the fins, significantly improving heat transfer performance.
Precision CNC Machining
Post-molding, we employ high-precision CNC machining for face milling, drilling, and tapping. This ensures flat mounting surfaces and accurate hole positioning for seamless integration into your assembly.
Surface Treatment
We offer professional surface finishing, primarily Anodizing (Clear/Black/Custom), to enhance corrosion resistance, electrical insulation, and aesthetic appeal.
