Product Description
Aluminum6061 Heat Sink Precision Extrusion Molding
Precision Extrusion Technology
The core of the aluminum radiator utilizes precision extrusion molding technology, employing specialized customized molds and high-precision extrusion equipment to integrate 6061/6063 high-purity aluminum alloy ingots into a single, seamless unit.
- Eliminates need for complex processes like splicing and welding
- Solves thermal conduction faults and loose structures in traditional radiators
- Precisely controls fin height, density, and thickness with uniform error ≤ 0.1mm
- Enables formation of dense teeth, wide surfaces, and irregular shapes
- Provides strong rigidity, excellent deformation resistance, and vibration resistance
Manufacturing Efficiency & Consistency
Compared to welding and casting processes, extrusion molding delivers superior production efficiency and product consistency.
- Increases production efficiency by more than 50%
- Ensures high consistency in batch production with minimal individual differences
- Achieves yield rate over 98%, significantly reducing production losses
- Ideal for mass production needs in photovoltaic power plants and new energy production lines
Precision Machining & Assembly
After extrusion molding, installation surfaces and positioning holes undergo CNC precision milling and grinding for optimal performance.
- Installation surface smoothness: Ra0.8μm or better
- Flatness error: ≤ 0.02mm
- Seamless fit with core heating elements, reducing contact thermal resistance
- Precision positioning holes enable direct assembly without secondary processing
- Improves equipment assembly efficiency and reduces labor costs
Surface Treatment & Durability
Advanced surface treatments enhance product longevity and performance in demanding industrial environments.
- Anodizing, sandblasting, or electrophoretic surface treatments
- Forms dense oxidation protective layer on aluminum surface
- Strengthens anti-oxidation, anti-corrosion, dust-proof, and wear-resistant properties
- Resists industrial environment hazards including dust, moisture, and oil
- Optimizes heat exchange efficiency and ensures long-term stable performance
