This aluminum alloy die casting is a small, cylindrical component formed using a die-casting mold. It features an all-black finish, multiple vertical anti-slip ribs along its exterior, and a circular threaded hole at the top; the interior reveals an assembly cavity, positioning posts, and connection points.
The aluminum die-cast part features a circular disc structure, with the outer rim, central area, and rear mounting surface formed in a single molding process. RUIXIN verifies dimensions—such as outer diameter, disc height, edge notches, and central bosses—against customer drawings, typically maintaining tolerances between ±0.10mm and ±0.30mm. The circular profile ensures visual consistency during mass production and facilitates subsequent assembly with components like lamp shades, face rings, or mounting hardware.
The front face of the aluminum die-cast part incorporates multiple screw bosses, locating holes, a central mounting position, and small raised features, demanding high mold precision and exacting post-processing standards. RUIXIN controls hole spacing, diameters, boss heights, and feature positioning based on 2D drawings or 3D files, accommodating common thread specifications such as M3, M4, and M5. For circular aluminum parts requiring multi-hole alignment, positional accuracy is critical for ensuring smooth subsequent assembly.
Multiple sets of radial ribs are distributed across the front face to increase the part's surface area. With a thermal conductivity typically ranging from 96W/m·K to 180W/m·K, the aluminum alloy is ideal for producing metal housings that require efficient heat transfer. Rib height, thickness, quantity, and angle can be adjusted according to drawings, enabling the development of circular die-cast parts with varying diameters, power ratings, and aesthetic specifications.
The aluminum die-cast part undergoes 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 60μm and 100μm. These treatments result in a cleaner appearance—highlighting the black outer rim, radial ribs, and silver-gray back—and a smoother edge feel, effectively minimizing visible casting marks, burrs, and localized color variations.
The aluminum die-cast part can be modified to meet project requirements, including adjustments to the outer diameter, central hole, edge notches, number of ribs, mounting boss positions, and surface color. RUIXIN supports processes including sample reverse engineering, drawing verification, mold development, and prototype validation, as well as secondary operations such as drilling, tapping, sandblasting, powder coating, and packaging coordination. For OEM aluminum die-casting orders, production details are confirmed based on assembly specifications and batch production schedules.
For industrial facility ceilings, these aluminum die-cast components serve as housings for circular high-bay lights. Compatible with light source boards, power modules, suspension brackets, and mounting hardware, they are ideal for lighting projects in production workshops, equipment zones, and large indoor spaces. Buyers can specify requirements based on fixture diameter, installation height, and project volume.
In warehouse and logistics centers, these aluminum die-cast parts are suitable for high-bay warehouse lights, aisle lighting, and loading dock fixtures. Designed to integrate with suspension hardware, wiring compartments, and lens covers, they facilitate the mass assembly of lights for sorting areas, entry/exit points, loading staging areas, and cargo handling zones.
For sports venue ceilings, these aluminum die-cast housings are suitable for arena lights, training facility lighting, or large-space suspended fixtures. Their circular design allows manufacturers to easily integrate them with suspension systems, light source modules, and mounting brackets. Project specifications—such as illumination area, mounting location, and aesthetic requirements—can be tailored to the specific project.
In commercial plaza atriums, these aluminum die-cast housings are used for large-scale public lighting fixtures. Their black finish complements the modern aesthetic of commercial spaces, making them suitable for corridors, open lounge areas, mall entrances, and shared public spaces. Buyers can customize options regarding color, mounting methods, and packaging.
In municipal transit waiting halls, these aluminum die-cast components serve as housings for public lighting fixtures. They integrate with suspension hardware, lenses, light source assemblies, and mounting screws to form complete fixtures, making them ideal for waiting areas, service halls, public walkways, and platform lighting projects. Orders can be placed based on drawing numbers, mounting hole configurations, and surface finish requirements.
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.
