High-Quality High-Performance Square Aluminum & Copper Skived Fin Heat Sink Suppliers - China Factory for LED & Industrial Electronics Supplier, Manufacturers
Product Description
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
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.

Major Features & Advantages
The high-density fin structure maximizes surface area within a compact footprint, solving overheating issues in confined spaces.
No solder joints or adhesive layers interfere with heat transfer, ensuring long-term reliability.
From fin height and thickness to base plate dimensions, we tailor every aspect to your thermal simulation requirements.
All parts undergo strict dimensional inspection and visual checks before packing (Foam + Carton protection).
Technical FAQ
A1: Yes, absolutely. We specialize in custom manufacturing. Please send your drawings (STEP, IGS, PDF) and we will provide a DFM (Design for Manufacturing) review and quote.
A2: Copper provides approximately 60% higher thermal conductivity than aluminum, making it ideal for extremely high-heat density components. Aluminum is lighter and more cost-effective, suitable for general industrial and LED applications.
A3: Yes. We understand that R&D and testing are crucial. We support our clients with low-volume prototyping (as low as 2 units) before moving to mass production.
A4: Generally, sample production takes about 7-10 days, while standard batch production is completed within 15-21 days, depending on the complexity and surface treatment required.
A5: We primarily offer professional Anodizing (Clear, Black, or Custom colors), along with degreasing and anti-oxidation treatments to enhance corrosion resistance, electrical insulation, and aesthetics.
A6: Yes, our engineering team provides a complimentary Design for Manufacturing (DFM) review to evaluate your design for optimal thermal performance and manufacturability before any tooling or cutting begins.
