The aluminum die-casting mold produces a circular aluminum die-cast housing characterized by a combination of a black outer rim and a silver-gray inner cavity. The front features a circular cover surface with a central hole, reinforcing ribs, and peripheral mounting holes; the interior reveals a deep cavity structure, a central boss, edge mounting points, and localized support areas.
The aluminum die casting mold is designed to produce circular aluminum housings featuring a black outer rim and a silver-gray inner cavity. The front face is circular, incorporating a central hole, reinforcing ribs, and peripheral mounting holes; the interior reveals a deep cavity structure, a central boss, edge mounting points, and localized support areas. RUIXIN develops the mold based on blueprints, defining the outer diameter, inner diameter, cavity depth, and edge thickness. Standard dimensional tolerances range from ±0.10mm to ±0.30mm, ensuring consistent appearance across mass-produced units.
The mold incorporates a central hole, peripheral mounting holes, internal bosses, and specific mounting surfaces, demanding high precision in both mold machining and post-casting finishing. RUIXIN accommodates processes such as drilling, reaming, tapping, and trimming; threaded holes can be specified to common standards like M3, M4, or M5. Hole spacing, diameters, and boss dimensions are verified against assembly drawings to minimize fitment discrepancies.
The circular housing requires an optimized wall thickness distribution for the rim and cavity, typically ranging from 2.5mm to 5mm, with localized thickening at mounting points to meet structural load requirements. During the mold development phase, parameters such as transition radii, draft angles, and boss heights are finalized to mitigate issues like short shots (incomplete filling), sink marks, deformation, and uneven edges.
Post-casting treatments include deburring, 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 clean contrast between the black outer rim and silver-gray inner cavity, along with a smooth tactile finish, meeting the strict aesthetic consistency standards required for mass production orders.
The aluminum die-casting mold allows for adjustments to the outer diameter, cavity depth, center hole size, number of mounting holes, edge openings, boss positions, and surface color based on project requirements. RUIXIN supports the entire process—from sample reverse engineering and drawing verification to mold development, trial validation, machining, sandblasting, powder coating, and packaging coordination—to meet OEM procurement needs for aluminum die-cast housings.
In outdoor lighting assembly workshops, these circular aluminum die-cast housings serve as back shells, mounting covers, or driver installation cavities. They can be integrated with light source boards, diffusers, gaskets, and mounting screws, making them suitable for streetlights, garden lights, and floodlights. Buyers can specify requirements based on the fixture's outer diameter, assembly orientation, and surface color.
At industrial equipment assembly sites, parts produced from these aluminum die-casting molds serve as circular equipment covers, mounting housings, or internal protective components. They can be installed on the equipment exterior, at connection interfaces, or in maintenance areas to facilitate screw fastening, cable routing, and structural shielding. Customers can confirm hole locations, wall thickness, and packaging methods based on equipment blueprints.
In warehouse lighting areas, these circular aluminum housings are used for high-bay lights, aisle lights, or loading dock fixture casings. They can be combined with suspension hardware, electrical modules, and light source assemblies, making them ideal for racking aisles, sorting zones, and loading/waiting areas. Procurement can be customized based on warehouse ceiling height, fixture dimensions, and project volume.
In commercial utility rooms, these aluminum die-cast components serve as housings for public lighting equipment, mounting faceplates, or electrical modules. The black finish complements modern commercial equipment aesthetics, while the circular design facilitates integration with suspension, wall-mount, or recessed hardware. Project teams can procure units based on interior design style, installation location, and delivery schedules.
In municipal public facility areas, parts produced from these aluminum die-casting molds are used for public lighting fixtures, equipment covers for transit platforms, or outdoor metal housings. The product is compatible with mounting brackets, cable access points, and external faceplates, making it suitable for installations in areas such as waiting zones, park walkways, service halls, and public passageways.
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.
