Die Casted Heat Sink Parts

Die Casted heat sink Parts are high-performance thermal management components manufactured using advanced die-casting technology. By injecting molten metal into precision molds under high pressure, these parts achieve complex geometries, high dimensional accuracy, and excellent repeatability.
These die cast heat sink parts are widely used in electronic devices to absorb and dissipate heat efficiently, ensuring stable operation, preventing overheating, and extending the lifespan of equipment. Materials typically include high-quality aluminum alloys or copper, offering optimal thermal conductivity and mechanical strength.

Manufacturing Process

1. Raw Material Management

• Aluminum alloys or copper ingots are inspected for chemical composition, mechanical properties, and surface quality.

• Material certificates (AMS/ASTM) are verified.

2. Mold Preparation

• High-precision die-casting molds are fabricated and tested.

• Preheating ensures stable casting conditions.

3. Melting & Casting

• Molten metal (Al or Cu) is injected under high pressure into the die mold.

• Rapid cooling and solidification achieve precise dimensions and complex shapes.

4. Demolding & Cleaning

• Cast parts are ejected, trimmed, and burrs removed.

• Cleaning ensures optimal thermal contact and surface quality.

5. Surface Treatment

• Optional anodizing, powder coating, or chemical passivation enhances corrosion resistance and thermal performance.

6. Precision Machining (Optional)

• CNC machining can refine key mounting surfaces, fins, or threaded holes to strict tolerances.

7. Inspection & Quality Control

• Dimensional inspection with CMM (flatness ≤0.1 mm, parallelism ≤0.08 mm)

• Thermal performance testing (flow, heat dissipation efficiency)

• Leak testing (if required) and visual inspection
