This low-pressure casting features a circular aluminum alloy housing with a black and silver-gray finish. The front side is characterized by closely spaced concentric ribs, a central cylindrical opening, and peripheral ventilation holes, while the back serves as a circular mounting plate featuring a central recess, screw holes, and elongated outer slots. The product resembles a circular luminaire housing or an aluminum heat-dissipation casing; production can be finalized based on drawings, samples, diameter, hole specifications, and surface color requirements.
Produced via low-pressure casting, the process involves a gentle filling of molten aluminum, making it ideal for circular housings, annular rims, and multi-ribbed structures. Wall thickness typically ranges from 2.5mm to 5mm, with localized thickening at mounting points as specified in drawings; this minimizes issues such as material shortages in thin-walled areas, edge deformation, and uneven molding.
The casting features multiple radial ribs on the front and ventilation holes along the outer rim, maximizing the surface area for heat exchange between the aluminum housing and the surrounding air. With an aluminum alloy thermal conductivity typically ranging from 96W/m·K to 180W/m·K, it is well-suited for applications requiring efficient heat conduction. Rib height, spacing, thickness, and orientation can be customized according to client specifications.
Incorporating features such as a center bore, screw holes, a circular rim, a mounting face, and localized bosses, this component demands high mold precision and exacting post-processing standards. RUIXIN controls critical dimensions—including outer diameter, hole spacing, face height, and assembly positions—based on 2D drawings or 3D files, typically maintaining tolerances between ±0.10mm and ±0.30mm.
Surface treatments include 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 clean contrast between the black outer rim and the silver-gray face, along with smooth edges and a reduction in visible casting marks and burrs.
Specifications such as outer diameter, center bore size, rib count, elongated edge slots, face depth, screw hole locations, and surface color can be tailored to project requirements. RUIXIN offers comprehensive support—covering mold development, sample validation, machining, drilling, tapping, surface finishing, and packaging—to meet OEM aluminum casting procurement needs.
These low-pressure castings are suitable for use as housings for circular, high-mounted light fixtures on industrial facility rooftops. The housing can be assembled with light source boards, power modules, suspension hardware, and mounting screws, making it suitable for lighting projects in production workshops, assembly areas, and large indoor spaces.
In warehousing and logistics centers, this type of circular aluminum housing is suitable for high-bay warehouse lights, aisle lighting, and loading dock fixtures. Buyers can specify housing dimensions based on rack height, installation location, fixture specifications, and project volume, facilitating mass assembly by manufacturers.
For stadium and arena ceilings, low-pressure cast housings are ideal for overhead lighting fixtures. The circular design integrates seamlessly with suspension systems, mounting brackets, and lighting modules, making it suitable for lighting projects in basketball arenas, training halls, badminton courts, and multi-purpose sports facilities.
In commercial plazas, these aluminum housings are suitable for lighting fixtures in public areas. The black finish complements the aesthetic of modern commercial spaces, and the housing supports suspension, wall-mounting, or bracket-mounting configurations—ideal for corridors, atrium perimeters, and open indoor areas.
For municipal public buildings, low-pressure cast housings are suitable for lighting fixtures in lobbies, waiting areas, service centers, and public corridors. Project teams can specify outer dimensions, mounting hole patterns, colors, packaging, and inspection requirements based on technical drawings, streamlining subsequent bulk procurement and on-site installation.
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.
