High-Efficiency Die Casting Solution for Lighting Heat Sink Enclosures with A380 Aluminum
Project Overview – Lighting Industry Demands on Thermal Enclosure Design
Modern lighting systems—especially LED fixtures—require more than just illumination. Thermal management, modularity, and durability are critical. Heat sink enclosures must integrate structural support, housing, and effective thermal dispersion in a compact design. Traditional multi-part assemblies no longer meet the streamlined requirements for IP65+ rated fixtures and high-efficiency lighting systems. Manufacturers need consistent, cost-effective metal casting solutions to maintain quality and production scalability.
Material Selection – Why A380 Aluminum is Ideal for Lighting Housings
A380 aluminum alloy is the industry standard for complex lighting enclosures. Its excellent fluidity supports thin-wall casting and intricate fin structures. With a thermal conductivity of 96 W/m·K and superior corrosion resistance, A380 enables long service life in both indoor and outdoor environments. The alloy is also highly compatible with custom aluminum die casting processes, supporting both structural performance and surface finish flexibility.
Manufacturing Process Breakdown
Precision Die Casting with A380
Our tool and die making specialists design molds with advanced thermal regulation and venting, allowing efficient cavity filling and high fin definition. Complex features are formed with precision sliders and core pulls. Wall thickness control to ±0.1 mm ensures strength-to-weight optimization.
CNC Machining for Mounting and Assembly Interfaces
CNC machining operations post-casting enable high-accuracy control of threaded holes, slots, and flat mounting surfaces. With ±0.05 mm tolerance for critical interfaces, components achieve consistent fit across mass production. Multi-axis machining also supports product customization with minimal tooling change.
Post-Processing – Sandblasting and Powder Coating
We apply sand blasting to prepare the surface and increase coating adhesion by uniformly roughening to Ra 1.6–3.2 μm. Followed by powder coating, the enclosures achieve RAL-compliant visual finish and corrosion resistance exceeding 500 hours of salt spray exposure. These treatments meet lighting sector demands for both durability and aesthetics.
