"Aluminum casting parts" refers to metal components produced through the aluminum casting process. The sample shown here is a circular, disc-shaped aluminum housing featuring a black outer rim combined with a silvery-gray inner surface. The front side incorporates multiple parallel ribs, circular apertures, and localized mounting bosses, while the back side displays a dense rib pattern, numerous screw bosses, an outer rim, and locating holes. The product resembles a circular light fixture housing, a heat-dissipation disc, or an industrial aluminum cover plate; production can be confirmed based on technical drawings, samples, diameter, hole specifications, and surface color requirements.
These aluminum casting parts feature a circular disc structure; the outer rim, inner flat surface, central area, and specific hole locations are all formed during the molding process. RUIXIN confirms specifications—such as outer diameter, thickness, rim width, and hole distribution—based on customer 2D drawings or 3D files, with standard dimensional tolerances ranging from ±0.10mm to ±0.30mm. The circular profile ensures consistent aesthetics for mass production and facilitates seamless assembly with components like faceplates, bases, or retaining rings.
The inner surface features multiple sets of parallel ribs and screw bosses, creating a distinct structural layout within the compact disc area. Rib height, thickness, and spacing are adjustable according to drawings, with standard wall thicknesses ranging from 2.5mm to 5mm. For large-diameter circular aluminum parts, a strategic rib layout helps minimize disc deformation, localized shrinkage, and edge unevenness, thereby enhancing mass production quality.
The surface incorporates multiple rows of elongated ribs to increase the contact area between the aluminum part and the surrounding air. With a thermal conductivity typically ranging from 96W/m·K to 180W/m·K, the aluminum alloy is ideal for metal housings requiring efficient heat transfer. RUIXIN adjusts rib orientation, spacing, and thickness based on product diameter, installation space, and structural drawings to meet the development needs of various circular aluminum castings.
The surfaces undergo processes such as deburring, trimming, sandblasting, powder coating, and painting. Sandblasting roughness can be specified between Ra3.2 and Ra6.3, while powder coating thickness is controlled within the 60μm to 100μm range. These treatments result in a cleaner appearance—highlighting the black outer rim, ribbed sections, and silver-grey inner surface—and a smoother edge feel, effectively minimizing casting marks, burrs, surface particulates, and color inconsistencies.
These aluminum casting parts allow for adjustments to the outer diameter, disc thickness, number of ribs, screw boss locations, hole specifications, outer rim openings, and surface color to meet specific project requirements. RUIXIN supports the entire process, including sample reverse engineering, drawing verification, mold development, prototype validation, and coordination regarding secondary operations (drilling, tapping, sandblasting, powder coating) and packaging. For OEM aluminum casting orders, production plans are finalized based on the client's assembly methods and procurement batch requirements.
For industrial facility ceilings, these aluminum castings serve as housings or backplates for circular high-bay lights. Compatible with light source boards, power modules, suspension hardware, and mounting screws, they are ideal for lighting projects in production workshops, equipment zones, and large indoor spaces. Specifications can be determined based on ceiling height, fixture diameter, mounting method, and project volume.
In warehousing and logistics centers, these circular aluminum products are used for the housings of high-bay lights, aisle lights, and loading dock fixtures. They integrate with lenses, wiring compartments, suspension brackets, and light source modules, making them suitable for sorting areas, entry/exit points, loading staging areas, and cargo transit zones. Product dimensions can be customized according to warehouse ceiling height, illumination coverage, and mounting location.
For sports venue roofs, these aluminum castings serve as housings for arena lights, training facility lights, or large-space suspended fixtures. Their circular, disc-like design facilitates integration with suspension systems, mounting brackets, and light source components. Production details can be finalized based on factors such as seating areas, the playing field, mounting height, and fixture layout.
In commercial plaza atriums, these aluminum castings are used for lighting fixture housings in large public spaces. The black outer rim complements the aesthetic of modern commercial facilities, making them suitable for corridors, open lounge areas, mall entrances, and shared spaces. Procurement specifications—including finish color, suspension method, fixture size, and packaging—can be customized.
In municipal public buildings, these aluminum castings serve as fixture housings for service halls, waiting areas, public corridors, and administrative offices. They are designed for assembly into complete lighting units using lenses, suspension hardware, light source components, and mounting screws. Project procurement orders can be placed based on drawing numbers, hole specifications, surface treatments, packaging requirements, and delivery batches.
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.
