Aluminum die-cast parts are formed from aluminum alloy using a die-casting mold into a rounded-rectangular housing; the exterior is dark grey-black, while the interior features a silver-grey metallic mounting surface. The product incorporates a lateral circular connector mount, a circular cable pass-through hole, reinforcing ribs along the edges, an internal mounting cavity, and multiple screw mounting points.
These aluminum die-cast parts are formed using molds, allowing for precise control over rounded outer frames, lateral mounting brackets, internal cavities, and hole layouts based on technical drawings. RUIXIN verifies dimensions—such as length, width, height, hole spacing, and edge profiles—against 2D drawings or 3D files. Standard dimensional tolerances typically range from ±0.10mm to ±0.30mm, ensuring consistent appearance and assembly fit across mass-production orders.
With a density of approximately 2.7g/cm³, aluminum alloy is significantly lighter than steel, making it ideal for large housings and mass-produced assembly components. The design combines hollow cavities with structural ribs to minimize overall weight while maintaining precise external dimensions. For aluminum housings requiring transport, assembly, and on-site installation, the lightweight material reduces handling strain and facilitates integration with brackets, light poles, or faceplates.
The internal structure features multiple linear ribs and open mounting areas, maximizing the surface area for heat exchange with the surrounding air. With a thermal conductivity typically ranging from 96W/m·K to 180W/m·K, aluminum alloy is an excellent choice for metal housings requiring efficient heat transfer. Rib height, spacing, thickness, and orientation can be customized according to product drawings, enabling the development of aluminum die-cast housings in various specifications.
The housings incorporate features such as cable routing holes, screw bosses, mounting holes, lateral pivot points, and internal locating surfaces, demanding high precision in both mold making and post-processing. RUIXIN offers secondary operations including drilling, tapping, trimming, and hole adjustment, with threaded holes available in common sizes such as M3, M4, and M5. For products requiring integration with lighting accessories or structural components, hole placement accuracy is critical for efficient downstream assembly.
Aluminum die-cast parts can undergo various surface treatments, including 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. After processing, the dark grey-black outer frame and silver-grey inner cavity appear neater, with smoother edges and corners; visible burrs, casting marks, and localized color variations are minimized, meeting the appearance standards for mass-produced aluminum parts.
For outdoor street light poles, these aluminum die-cast parts serve as luminaire housings, driver compartments, or bracket connectors. A lateral circular mount allows for connection to the pole arm, while the internal cavity accommodates the light source board, wiring components, and mounting hardware. Buyers can specify dimensions based on pole height, beam angle, and luminaire specifications.
In industrial parks, these aluminum die-cast housings are suitable for roadway lights, security gate lights, and equipment access path lighting. The dark gray-black finish suits industrial environments, and the rounded-rectangular shape facilitates assembly with the lens cover and mounting bracket. Project teams can order custom batches based on mounting orientation, housing dimensions, mounting hole locations, and packaging requirements.
At logistics warehouse loading docks, these aluminum housings are used for lighting fixtures covering truck bays, warehouse entrances, and cargo transfer zones. The housing integrates with brackets, light source boards, and wiring compartments for assembly. Customers can specify product details based on platform width, wattage, and mounting method.
At commercial parking lot entrances, these aluminum die-cast parts serve as housings for access lane lights, entry/exit lights, and parking area illumination. The rectangular housing design allows for easy mounting on poles, wall brackets, or cantilever structures. Buyers can select the finish color and packaging method based on the parking lot's aesthetic, required illumination range, and project scale.
For municipal public walkways, these aluminum die-castings serve as outdoor lighting housings for plaza perimeters, pedestrian paths, park trails, and recreational areas. Products can be customized to match specific luminaire designs, mounting heights, and site constraints, facilitating the procurement and installation of complete public lighting systems.
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.
