This high-pressure die-cast aluminum housing features a circular design, combining a black outer rim with a silver-gray inner cavity. The exterior is arrayed with a ring of curved cooling fins, while the top surface incorporates a square mounting area, a central aperture, and screw mounting points. The interior features a deep, circular cavity structure with visible rectangular mounting zones, peripheral holes, and localized raised bosses. The component resembles the housing of a circular industrial light fixture; production can be finalized based on drawings, samples, dimensions, and specified surface colors.
High-pressure casting rapidly fills the mold cavity with molten aluminum, making it ideal for forming circular housings, deep-cavity structures, and dense rib patterns. RUIXIN adjusts mold designs based on product dimensions, wall thickness, and structural features—typically accommodating wall thicknesses of 2.5mm to 5mm—to minimize issues such as material shortages, sink marks, and uneven molding.
The outer ring of the casting features multiple curved heat-dissipation ribs, increasing the surface area for air contact. With an aluminum alloy thermal conductivity typically ranging from 96W/m·K to 180W/m·K, the material is well-suited for metal housings requiring efficient heat transfer. Rib height, spacing, thickness, and orientation can be customized according to blueprints to meet specific structural requirements.
The housing incorporates features such as a center hole, screw holes, a rectangular mounting surface, edge mounting points, and internal cavity bosses, demanding high mold precision and post-processing accuracy. RUIXIN controls hole spacing, outer diameter, cavity depth, and mounting surface positioning based on 2D drawings or 3D files, typically maintaining dimensional tolerances between ±0.10mm and ±0.30mm.
Castings 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. These treatments result in a clean contrast between the black outer ring and silver-gray inner cavity, ensure smooth edges, and eliminate noticeable burrs or localized color inconsistencies.
Outer diameter, cavity depth, rib count, center hole size, mounting surface shape, and surface color can all be adjusted to meet project requirements. RUIXIN provides comprehensive support—covering mold development, sample validation, machining, drilling, tapping, sandblasting, powder coating, and packaging—to fulfill OEM aluminum die-casting procurement needs.


For industrial facilities, these high-pressure cast components serve as housings for circular high-bay luminaires. Compatible with light source boards, power modules, and mounting brackets, they are ideal for assembly projects destined for workshops, production lines, and large indoor spaces; buyers can specify dimensions based on wattage and installation height.
In sports arenas, these high-pressure cast parts are used as housings for circular arena lights, pendant fixtures, or high-bay lights. Their compact, circular design facilitates modular assembly for manufacturers. Custom production is available to meet specific requirements regarding illumination coverage, mounting methods, and exterior colors.
In warehouse and logistics centers, these high-pressure cast components serve as housings for high-bay lighting fixtures. Suitable for aisleways, sorting zones, and loading/unloading areas, the housings integrate with driver compartments, light source boards, and suspension hardware, making them ideal for bulk procurement.
In shopping mall public areas, these high-pressure cast components are used for indoor general lighting or large-space fixtures. Their black finish complements modern commercial aesthetics, and they can be manufactured to meet specific requirements for suspension methods, dimensions, and surface colors—making them suitable for atriums, corridors, and public seating areas.
In airport departure lounges, these high-pressure cast components serve as housings for large-space lighting fixtures. Their circular structure allows for easy integration with suspension systems and lighting modules, making them ideal for public infrastructure projects requiring uniform aesthetics across large quantities. Buyers can specify mounting hole locations, outer diameters, packaging, and surface finish requirements based on project blueprints.
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.
