This aluminum mold casting is a small, cylindrical aluminum component formed via a molding process; it features an all-black finish and resembles a circular end cap or connecting sleeve. The front face features a central circular hole, an annular groove, and small holes on either side, while the back reveals internal cavity slots, an arc-shaped opening, and positioning structures.
The aluminum casting features a small, cylindrical profile, making it ideal for developing aluminum parts where space is at a premium. Key dimensions—such as outer diameter, height, hole depth, and internal cavity size—are verified against technical drawings, with wall thicknesses typically ranging from 2mm to 4mm. With an aluminum alloy density of approximately 2.7g/cm³ (significantly lighter than steel), the parts are easy to package, transport, and assemble in bulk. For small components like connectors, end caps, and fasteners, precise dimensional control is crucial for ensuring a proper fit during subsequent assembly.
The casting incorporates a central hole, small side holes, internal cavity slots, and annular steps, demanding high mold accuracy and precise post-processing. RUIXIN controls parameters such as hole diameter, hole spacing, slot depth, and end-face height based on 2D drawings or 3D files, typically maintaining dimensional tolerances between ±0.05mm and ±0.20mm. Features such as holes and slots undergo drilling, reaming, tapping, and trimming to ensure compatibility with screws, shafts, or positioning components.
The casting requires high-quality finishing on its outer circular edges, end-face steps, and internal cavity corners. RUIXIN offers processes including deburring, trimming, sandblasting, powder coating, and painting; sandblasting roughness is typically specified between Ra3.2 and Ra6.3, while powder coating thickness is controlled between 60μm and 100μm. These treatments result in a uniform black finish and smooth edges around central holes and annular slots, minimizing visible casting marks, burrs, and localized color variations.
The design integrates a central hole, positioning holes, internal cavity slots, and an outer cylindrical profile into a compact form factor. Internal features such as reinforcing ribs, locking slots, or mounting steps can be incorporated according to drawings, with specific hole diameters, slot widths, and step heights determined by assembly requirements. This compact structure minimizes the part's footprint, making it suitable for small aluminum die-cast products requiring concealed mounting, end-point fixation, or localized connections.
For aluminum mold castings, specifications such as outer diameter, height, center hole size, side hole positioning, internal cavity shape, annular groove depth, and surface color can be adjusted to meet project requirements. RUIXIN supports the entire process, including sample measurement and mapping, drawing approval, mold development, prototype validation, and coordination on machining (drilling, tapping), surface finishing (sandblasting, powder coating), and packaging. For OEM orders of small aluminum castings, production details are finalized based on assembly requirements, batch quantities, and delivery schedules.
For luminaire bracket connections, aluminum mold castings are suitable for small connecting sleeves, rotating end caps, or fixed circular mounts. These components integrate with screws, support rods, luminaire housings, and adjustment mechanisms to facilitate angular connections, end-point anchoring, or localized locking. Buyers can specify dimensions based on bracket diameter, hole orientation, and finish color; these parts are ideal for outdoor lighting, floodlights, and industrial lighting applications.
On machinery control panels, aluminum mold castings serve as knob bases, circular covers, or positioning mounts. They can be installed on the panel exterior or at fixed internal locations, working in conjunction with screws, shafts, and plastic components. Customers can finalize specifications based on panel thickness, aperture size, and mounting orientation, streamlining both initial assembly and subsequent maintenance or replacement.
At the ends of automation fixtures, aluminum mold castings function as positioning end caps, limit sleeves, or small locking components. Their compact size allows for easy installation on fixture sides, slider ends, or adjustable structural points. Buyers can determine dimensions based on movement direction, connection hole specifications, and assembly/disassembly requirements; these parts are well-suited for automation equipment, tooling fixtures, and inspection jigs.
In furniture hardware assembly, aluminum mold castings are used for adjustable bases, circular connecting covers, decorative end caps, or bracket mounts. Their black finish complements modern hardware aesthetics, and they integrate seamlessly with metal rods, screws, and support structures. Customization options—including product series, surface color, packaging, and hole specifications—facilitate mass assembly and organized shipping.
In industrial maintenance settings, aluminum mold castings serve as small replacement parts, end caps, or connectors. They can be procured based on part numbers, hole diameters, outer diameters, heights, and surface colors, allowing maintenance personnel to quickly match parts to installation points. These components are ideal for repair and replacement needs across lighting systems, tools, support structures, and small mechanical modules.
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.
