This die-cast aluminum alloy component is a rectangular, deep-cavity housing featuring a black border combined with a silver-gray interior. The front side incorporates a rectangular mounting surface, screw holes, and recessed beveled edges, while the rear side displays vertical reinforcing ribs, mounting tabs along the edges, and lateral connection structures. Its overall design resembles an industrial light fixture housing; production can be executed based on provided drawings, samples, dimensions, and specified surface colors.
These components are formed from aluminum alloys—materials with a density of approximately 2.7 g/cm³—making them significantly lighter than steel counterparts. For large rectangular housings, this lightweight material helps reduce the overall weight of the assembly. RUIXIN selects common die-casting alloys such as ADC12 and A380 based on specific product dimensions, wall thickness, and structural requirements.
Featuring rectangular mounting surfaces, screw holes, mounting tabs, lateral connection points, and internal stepped cavities, these parts demand high mold precision and exacting post-processing standards. RUIXIN controls dimensions—including length, width, hole spacing, and mounting surface positioning—based on 2D drawings or 3D files, typically maintaining dimensional tolerances between ±0.10 mm and ±0.30 mm.
The interior of the housing features multiple vertical ribs that increase the internal metal surface area for heat transfer. With a thermal conductivity generally ranging from 96 W/m·K to 180 W/m·K, these aluminum alloy housings are ideal for applications requiring efficient heat dissipation. Rib height, spacing, and thickness can be adjusted according to drawings to meet diverse specifications.
Surfaces undergo treatments such as deburring, trimming, sandblasting, powder coating, and painting. Sandblasting roughness can be specified within the Ra3.2 to Ra6.3 range, while powder coating thickness is controlled between 60 μm and 100 μm. These treatments result in a clean appearance—contrasting a black outer frame with a silver-gray inner cavity—and ensure smooth, refined edges.
Housing dimensions, cavity depth, hole configurations, rib layouts, mounting tab positions, and surface colors can all be tailored to project requirements. RUIXIN supports the entire process—from mold development and sample validation to drilling, tapping, surface finishing, and packaging—to fully meet OEM aluminum die-casting procurement needs.
In building facade lighting applications, these die-cast aluminum alloy housings serve as casings for floodlights, spotlights, or wall-mounted fixtures. Their rectangular shape facilitates the installation of light source boards, lens panels, and mounting hardware, making them ideal for illuminating commercial buildings, office facades, and campus complexes.
For stadium grandstand areas, die-cast aluminum alloys are used for high-power lighting fixture housings. Given the high mounting positions, the housings are designed to integrate seamlessly with brackets, mounts, and wiring assemblies. Buyers can specify housing dimensions based on beam angles, fixture size, and mounting requirements.
At factory loading docks, these aluminum housings are suitable for platform lights, passageway lights, or warehouse door lighting. The internal cavity accommodates light source components, while the outer frame integrates with covers and fasteners, supporting night-time loading/unloading, vehicle docking, and exterior facility lighting.
In port and terminal areas, these die-cast aluminum housings are used for outdoor industrial lighting equipment. The black finish is well-suited for industrial environments, and the rectangular shape allows for modular assembly by manufacturers. Bulk procurement can be tailored to specific pole heights, mounting orientations, and site quantities.
In logistics and warehouse aisles, die-cast aluminum alloy housings are used for high-bay fixtures, area lights, and aisle lighting. The housings accommodate light source boards, driver compartments, and mounting brackets, making them ideal for lighting projects covering racking aisles, sorting areas, entry/exit points, and vehicle staging areas.
We are a manufacturing company specializing in aluminum die casting, in-house tooling, and secondary processing for stable volumeproduction. With a practical engineering mindset and a production system built around repeatabity, we support customers from molddevelopment through mass production, delivering consistent parts with reliable lead time control.
Our core capability is high pressure die casting supported by dedicated machining and finishing operations. By managing tooling, processvalidation, and production control under one root we reduce quality variation and keep project schedules predictable. For customers whorequire ready-to-assemble parts, we provide drlling, tapping, trimming, and fixture-based machining to maintain dimensional consistency frombatch to batch.
To meet functional and appearance requirements, we offer surface preparation and finishing options incuding sandblasting and powdercoating. Each projectis handled with clear checkpoints, from incoming inspection and in-process controlto final inspection before shipmentwith documentation support for commercial-grade requirements and bulk orders.
We work as an OEM and ODM solution provider for global projiect buyers who value stable manufacturing. responsive engineering support, andlong -term production continuity. Whether you are developing a new product or optimizing an existing design, we focus on making parts that are consistent, scalable, and ready for real-world use.
