This die-cast aluminum component is an elongated rectangular housing featuring a dark gray-black finish and a frame with rounded edges. The front face incorporates a large metal mounting surface, a pattern of ventilation holes, circular cable access ports, and a dedicated electrical component compartment; the rear features multiple rows of reinforcing ribs, while the ends are equipped with circular mounting bosses. Designed with the aesthetic of an outdoor lighting housing, the part boasts a refined surface texture achieved through sandblasting or powder coating and can be manufactured according to specific drawings, samples, and color requirements.
These die-cast parts are formed using precision molds, allowing for strict control over the elongated frame, rounded edges, side mounting brackets, and internal mounting surfaces according to specifications. RUIXIN verifies dimensions—such as length, width, height, hole locations, and edge profiles—against 2D drawings or 3D files. Standard dimensional tolerances typically range from ±0.10mm to ±0.30mm, ensuring consistent appearance across mass-production orders.
The rear of the die-cast part features multiple rows of linear cooling fins, increasing the surface area for heat exchange between the aluminum housing and the surrounding air. With an aluminum alloy thermal conductivity generally ranging from 96W/m·K to 180W/m·K, these parts are ideal for metal housings requiring efficient heat transfer. Fin height, spacing, and thickness can be customized based on drawings to meet specific structural requirements.
The housing incorporates features such as screw bosses, cable pass-throughs, hinge holes, mounting slots, and internal component cavities, demanding high mold accuracy and precise post-processing. Hole diameters, spacing, and face positions are controlled through processes like drilling, tapping, and trimming. Threaded holes can be specified in common sizes (e.g., M3, M4, M5) to ensure seamless assembly with other components.
The parts undergo surface treatments such as deburring, 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 60μm and 100μm. These treatments result in uniform color and smooth edges, effectively minimizing visible casting marks, burrs, and localized color variations.
Housing dimensions, cooling fin orientation, hole configurations, internal cavity layouts, mounting brackets, and surface colors can all be tailored to project needs. RUIXIN supports the entire process—from mold development and sample validation to machining, surface finishing, and packaging—to meet procurement requirements for OEM aluminum die castings and custom aluminum alloy parts.
These die-cast parts serve as aluminum housings for street light heads mounted on urban roadway poles. Their elongated shape facilitates integration with light source boards, lens panels, and wiring components, while the circular side connector fits seamlessly with pole arms, making them ideal for mass assembly in roadway lighting projects.
In industrial park passageways, these die-cast parts are suitable for factory road lights, security gate lights, and exterior wall-mounted walkway lights. Their clean design and dark gray-black finish blend well with industrial environments; buyers can specify housing dimensions based on project location, desired aesthetics, and mounting orientation.
At logistics warehouse loading docks, these die-cast parts serve as housings for lighting fixtures illuminating vehicle docking areas, cargo transfer zones, and warehouse entrances. The aluminum housing integrates with brackets, wiring compartments, and light source modules to form a complete fixture capable of covering these operational areas.
At commercial parking lot entrances, these aluminum housings are used for passageway lights, entry/exit lights, and pole-mounted fixtures. Their rectangular shape allows for easy integration with poles, wall brackets, or cantilever structures, making them suitable for underground garage entrances, open-air parking lots, and parking area lighting.
These die-cast parts are suitable for outdoor lighting fixtures in public areas such as municipal plaza walkways. Their dark finish complements the style of public infrastructure, and the housings can be customized based on walkway width, lighting angles, and installation methods, making them ideal for plaza perimeters, pedestrian paths, and recreational walkways.
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.
