1. What is a Die-Cast Heat Sink?

A die-cast heat sink is a product made by injecting molten metal materials such as aluminum alloy or zinc alloy into a mold under high pressure to form the component in one go. Compared to traditional extruded or stamped heat sinks, the die-casting process allows for more complex structures, higher dimensional accuracy, and better surface finish.

2. Main Advantages

1. Flexible and Diverse Structures
The die-casting process supports customization of various complex structures, such as integrated fins, mounting holes, and wiring chambers, reducing the need for multiple processing steps.

2. Excellent Heat Dissipation Performance
Made from highly thermally conductive aluminum alloys (such as ADC12 and A380), die-cast heat sinks, when properly designed, offer excellent thermal conductivity and heat dissipation efficiency.

3. High Strength and Corrosion Resistance
Die-cast components have high density, strong mechanical properties, and are not easily deformed, making them suitable for outdoor and harsh industrial environments.

4. Attractive Appearance
Surfaces can be treated with powder coating, electrophoresis, anodizing, and more to enhance aesthetics and durability.

3. Common Application Scenarios

·LED Lighting Heat Sinks: Main bodies for LED street lights, floodlights, high bay lights, etc.

·Power Module Housings: Serve as both structural components and heat sinks.

·Automotive Electronics: Such as battery management systems and onboard control modules.

·New Energy Equipment: Heat dissipation units for photovoltaic inverters and energy storage systems.

·Communication Devices: Enclosures and heat sinks for 5G base stations.
