Core Mechanical Components

🔷Product Overview

Our die casting aluminum heatsinks are engineered for superior heat dissipation and durability. Designed for demanding applications in electronics, LED lighting, automotive, and renewable energy systems.

🔷Features

• Corrosion protection — Extend service life in harsh environments.
• Improved thermal emissivity — Better heat dissipation via anodizing or coatings.
• Enhanced appearance — Color matching and branding options.

🔷Common Surface Treatment Options

• 1. Anodizing
• Hard anodizing for wear resistance
• Decorative anodizing with color choices (black, silver, red, blue, gold, etc.)
• Improves emissivity and corrosion resistance
• 2. Powder Coating
• Durable, colorful finish
• Good for non-critical thermal surfaces
• Excellent mechanical protection
• 3. Chromate Conversion Coating (Alodine)
• Conductive surface for EMI shielding
• Corrosion protection without changing dimensions
• Suitable for grounding applications
• 4. Electroplating
• Nickel, tin, or silver plating for conductivity
• Enhanced wear resistance and corrosion protection
• 5. Sandblasting / Polishing /Matte
• Uniform surface texture before anodizing or painting
• Improves adhesion of coatings
• 6. Laser Engraving
• Permanent, high-contrast marking for part numbers, logos, or serial codes
• No ink, no fading — resistant to wear, heat, and chemicals
• Can be applied directly to anodized or bare aluminum
• Ideal for branding, traceability, and compliance markings

🔷Surface Treatment Comparison Table

Process	Typical Thickness	Corrosion Resistance	Wear Resistance	Thermal Effect	Appearance & Color Options	Special Advantages
Anodizing	5–30 µm	★★★★☆	★★★☆☆	↑ Improves emissivity	Black, silver, red, blue, gold, custom colors	Increases heat radiation, strong corrosion protection
Powder Coating	50–150 µm	★★★★☆	★★★★☆	↓ Slightly lower	Wide RAL/Pantone range	Excellent mechanical durability, thick protective layer
Chromate Conversion	<1 µm	★★★☆☆	★★☆☆☆	Neutral	Yellow, clear, olive drab	Maintains conductivity, good for EMI shielding
Electroplating	5–10 µm	★★★★☆	★★★★☆	↓ Slightly lower	Metallic finish (nickel, tin, silver)	High conductivity, good wear protection
Sandblasting / Polishing/ Matte	N/A	Depends on top coat	★★☆☆☆	Neutral	Matte or brushed metallic	Creates uniform texture, improves coating adhesion
Laser Engraving	N/A	N/A	Permanent mark	Neutral	High-contrast engraving (usually white on anodized)	Permanent, precise branding & traceability without chemicals
