Lighting Project Aluminum Die Casting Parts | Sandblasted Round Mounting Plates & Covers
OVERVIEW Custom aluminum die casting components for lighting projects, including round mounting plates, ceiling rose bases, and fixture end caps. Manufactured from AlSi12Fe (EN AC-43400) casting alloy—a high-silicon, corrosion-resistant aluminum grade that naturally resists rust and oxidation, making it well-suited for indoor and semi-outdoor lighting environments. Parts are produced via High-Pressure Die Casting (HPDC), followed by CNC machining for precise hole patterns and threading, and finished with uniform sandblasting as a ready-to-paint substrate for the customer's final coating process. MANUFACTURING SPECIFICATIONS • Material: AlSi12Fe (EN AC-43400) – European-standard casting aluminum alloy • Alloy Characteristics: ~10–13% Silicon, 0.6–1.1% Iron; excellent fluidity, pressure tightness, and natural corrosion resistance • Process: High-Pressure Die Casting (HPDC) + CNC Drilling & Tapping + Sandblasting • Surface Finish: Glass-bead or aluminum-oxide sandblasting for a uniform matte texture (customer applies final paint/powder coat) • Machining: Precision-drilled mounting holes, tapped threads, and wire-exit ports • Dimensional Control: Flatness and hole-position tolerance controlled via CNC • Corrosion Behavior: Silicon-rich surface forms a stable passive layer; inherently resistant to rust without additional plating KEY ADVANTAGES • Naturally Rust-Resistant: AlSi12Fe's silicon-iron composition provides inherent corrosion protection—no plating or anodizing required for many lighting applications. • Ideal Paint Base: Sandblasted surface creates excellent mechanical tooth for the customer's final coating, reducing peel and bubble risks. • European Material Standard: AlSi12Fe compliance signals traceability and alloy consistency for EU-based lighting brands. • Pressure-Tight Casting: Good fluidity and low hot-tear tendency yield dense, porosity-controlled parts. • Ready-to-Assemble: CNC-machined holes and threads ensure accurate fit with drivers, LED modules, and suspension kits. • Cost-Efficient Volume: Die casting + sandblast finish delivers a functional, paintable part at competitive unit cost. TYPICAL APPLICATIONS • LED panel light mounting brackets • Ceiling light rose bases and canopy plates • Track lighting fixture end caps • Downlight and spotlight housing components • Commercial and residential lighting project hardware • Lamp driver boxes and decorative covers PROCESS NOTE AlSi12Fe requires controlled melt temperature and die temperature to avoid die soldering and to maintain surface finish. Sandblasting parameters are tuned to achieve consistent Ra without embedding media into the softer aluminum matrix. All sharp edges are broken and burrs removed. Parts are packed to protect the sandblasted surface during transit, arriving clean and ready for the customer's paint line. QUALITY ASSURANCE • Material certificate (mill cert) confirming AlSi12Fe chemistry per EN 1706 • CMM inspection of hole positions, flatness, and critical dimensions • Thread gauge verification on all tapped holes • Surface roughness (Ra) check post-sandblasting • Visual inspection for sandblasting uniformity and cleanliness • COC and FAIR available per customer requirements
