KINGKA Tech Industrial Limited specializes in custom die casting heat sinks for electronic cooling and industrial thermal management applications. By combining high-pressure die casting, precision CNC machining, and customized surface finishing, we manufacture aluminum heat sinks designed to meet specific thermal performance, dimensional, and structural requirements.
As an experienced custom die casting heat sink manufacturer, we provide OEM and ODM services, supporting customers from initial design and prototype development to mass production. Our die cast heat sinks are suitable for applications requiring complex fin structures, integrated mounting features, consistent dimensions, and cost-effective large-volume manufacturing.
Our aluminum die casting heat sink manufacturing process injects molten aluminum alloy into a precision steel mold under high pressure. This process enables the production of complex geometries, integrated mounting holes, thin walls, and detailed fin structures.
Common materials include ADC12 and A380 aluminum alloys. Material selection depends on thermal conductivity, castability, mechanical strength, corrosion resistance, and the requirements of the final application.
Every thermal management project has different heat loads, airflow conditions, and installation constraints. We work with customer drawings, 3D CAD files, or physical samples to develop customized die cast heat sinks.
Key design considerations include:
Fin geometry: Fin height, thickness, spacing, and surface area are optimized for the available airflow and cooling requirements.
Base plate design: Base thickness and mounting surfaces are designed to support efficient heat transfer from electronic components.
Thermal performance: Heat dissipation requirements, ambient temperature, and airflow conditions guide the design process.
Precision machining: CNC milling, drilling, tapping, and surface finishing can be applied to critical mounting areas.
Structural integration: Mounting bosses, ribs, and fastening features can be incorporated into a single component to reduce assembly complexity.
A properly designed aluminum die casting heat sink increases the available surface area for convection, helping transfer heat from electronic components to the surrounding air. Fin layout and airflow direction are important factors in achieving the required thermal performance.
Die casting supports intricate shapes and integrated features that may require multiple parts or additional assembly when manufactured using other processes. This makes custom die cast heat sinks suitable for compact electronic enclosures and high-volume industrial products.
Although die casting requires an initial mold investment, it can offer competitive unit costs for medium- to high-volume orders. Repeatable production also helps maintain consistent component dimensions across manufacturing batches.
Depending on the application, available finishing options may include powder coating, painting, anodizing where the alloy and process are suitable, and other protective treatments. Surface treatment is selected according to corrosion resistance, appearance, electrical requirements, and thermal design.
Our custom aluminum heat sinks can be designed for a wide range of thermal management applications, including:
LED lighting: Heat dissipation for high-power LED lamps, streetlights, and industrial lighting fixtures.
Power electronics: Cooling for inverters, power supplies, rectifiers, and electronic control modules.
Automotive electronics: Thermal management for electronic housings, power modules, and control systems.
Telecommunications: Cooling components for communication equipment and network devices.
Industrial equipment: Heat sinks for motor controllers, automation systems, and industrial electronics.
Renewable energy: Thermal management components for solar inverters and related power conversion equipment.
Design review: Evaluate drawings, material requirements, heat load, and installation conditions.
Mold development: Design and manufacture the die casting mold based on the approved component geometry.
Die casting: Produce aluminum components through controlled high-pressure injection and solidification.
Trimming and CNC machining: Remove excess material and machine critical surfaces, holes, and threads.
Surface finishing: Apply the specified coating or surface treatment.
Quality inspection: Check dimensions, surface quality, and structural integrity. Thermal performance testing can be arranged according to project requirements.
Packaging and delivery: Package finished components according to customer specifications.

ADC12 and A380 aluminum alloys are commonly used because of their castability, mechanical properties, and suitability for complex geometries. The appropriate alloy depends on the application's thermal and structural requirements.
Yes. Custom heat sinks can be developed from 2D drawings, 3D CAD files, or physical samples, subject to design review and manufacturing feasibility.
Yes, when the material, fin geometry, base thickness, and airflow are properly designed. For demanding applications, thermal simulation and prototype testing can help verify the design before mass production.
Die casting is well suited to complex shapes and integrated structural features. Extrusion is generally effective for long profiles with a consistent cross-section. The best process depends on geometry, thermal performance, tooling costs, and production volume.
Yes. CNC machining can improve the accuracy of mounting surfaces and threaded holes, while suitable surface treatments can improve appearance and provide additional surface protection.
