Die-Cast Heat Sink

Die Casting Process Advantages

Our die casting technology combines precision engineering with efficient production capabilities

Complex Shapes

Die casting allows intricate designs including undercuts, thin walls, and integrated features that would be impossible or costly with other manufacturing methods.

Superior Thermal Performance

Utilizing high-conductivity aluminum alloys (A380, ADC12) with thermal conductivity up to 96 W/mK for efficient heat transfer and optimal cooling performance.

Cost Efficiency

Reduced machining operations, minimal material waste, and rapid production cycles make die casting ideal for medium to high-volume manufacturing.

Frequently Asked Questions

Common questions about die-cast heat sinks

What are the advantages of die-cast heat sinks over extruded types?

Die-cast heat sinks offer greater design flexibility with complex 3D geometries, integrated mounting features, and variable fin patterns. They excel in applications requiring intricate shapes, undercuts, or asymmetric designs that cannot be achieved through extrusion.

What aluminum alloys are used for die-cast heat sinks?

We primarily use A380 and ADC12 aluminum alloys, which offer excellent castability, good thermal conductivity (96-113 W/mK), and superior mechanical properties. These alloys are specifically formulated for die casting applications.

What is the minimum order quantity for die-cast heat sinks?

Due to tooling costs, die casting is most economical for medium to high volumes. Typical minimum order quantities range from 500-1000 pieces depending on part complexity. We can discuss specific project requirements during consultation.

Can die-cast heat sinks be customized with specific colors?

Yes, we offer various surface finishing options including anodizing in multiple colors (black, natural, custom colors) and powder coating in virtually any RAL color. These finishes also provide corrosion resistance and enhanced durability.

How does thermal performance compare to other heat sink types?

While die-cast aluminum has slightly lower thermal conductivity than pure aluminum extrusions, the ability to create optimized fin designs, larger surface areas, and integrated thermal paths often results in comparable or superior overall thermal performance.

Do you provide thermal simulation and design assistance?

Yes, our engineering team provides comprehensive design support including thermal analysis, CFD simulation, and design optimization. We work closely with customers to ensure heat sink designs meet specific thermal and mechanical requirements.
