Product Introduction

We provide CNC precision machining and high-pressure precision die-casting dual-process solutions to create high-performance housings for outdoor floodlights, industrial searchlights, and stage lighting equipment:

CNC process: Adopts a five-axis linkage machining center, suitable for small-batch customization and complex structures (such as thin-walled deep cavities/special-shaped curved surfaces), and uses 6061-T6/7075-T6 as the material, with an accuracy of ±0.01mm, meeting military-grade heat dissipation and IP68 protection requirements.

Die-casting process: Based on 2800T die-casting machine + vacuum-assisted technology, mass production of ADC12/A380 aluminum alloy housings achieves low-cost and high-efficiency production, with a minimum wall thickness of 1.2mm and a daily production capacity of over 5,000 pieces, suitable for rapid delivery of standardized products.

Product Feature And Application

CNC Process Advantages

Five-axis precision machining: linkage milling of complex lens slots/mounting flanges, one-piece molding to eliminate seams, and waterproofness increased by 50%.

Topological optimization and weight reduction: Finite element analysis (FEA) achieves wall (1.5mm) and high strength (compression resistance>150MPa)

Balanced military-grade heat dissipation: densely packed fins (spacing 2mm) + vacuum brazing temperature plate, thermal resistance ≤0.15°C/W.

Advantages of die-casting process

High efficiency and low cost: single-mode life of 200,000 times, cost is 60% lower than CNC (orders of more than 5,000 pieces).

Vacuum-assisted casting: porosity ≤0.5%, X-ray detection meets ASTM E505 first-level standard.

Near-net molding: reduce post-processing steps, surface roughness Ra≤3.2um.

Common advantages

Full environmental protection: IP68 sealing structure (CNC: double O-ring; die casting: secondary injection process)

Intelligent compatibility: pre-set DALI/PWM signal line duct, support EMC shielding (nickel plating/conductive oxidation).

Quick response: CNC supports 3-day expedited proofing, and die casting provides mold flow analysis report

Application scenarios

CNC processing

Military/navigation searchlight (high strength and corrosion resistance)

Customized stage lighting (special-shaped surface + hollow carving)

Ultra-thin outdoor floodlight (wall thickness ≤2mm)

Precision die casting

Municipal road lighting (mass standardization)

Portable emergency light (lightweight one-piece molding)

Product Details

Precision CNC one-piece molding, tolerance control at ±0.01mm, to ensure accurate hole position and tight fit.

Aluminum alloy shell has the advantage of natural thermal conductivity and excellent heat dissipation performance, which effectively reduces the internal working temperature and prolongs the product life.

With nano-level anti-UV surface treatment anodizing, it is corrosion-resistant and does not fade. It is available in a variety of colors such as silver, white, and black, which is beautiful and wear-resistant.

FAQ

Q: How to choose CNC or die-casting process?

A: Decision based on order quantity and structural complexity:

CNC: small batch (<500 pieces), complex structure (deep cavity/thin wall), high mechanical performance requirements (7075-T6).

Die casting: large batch (>3000 pieces), regular structure, cost-sensitive projects.

Q: Why do die castings need T6 heat treatment?

A: Through solution + aging treatment, the yield strength (↑30%) and dimensional stability of ADC12 are improved to adapt to the temperature difference of -40℃~120℃.

Q: How does CNC processing control deformation?

A: Adopt multi-axis synchronous processing strategy + residual stress elimination process (vibration aging/heat treatment), and the flatness reaches 0.05mm/m².

Q: Die casting mold life and cost?

A: The mold core is made of SKD61/H13 steel (HRC48-52), with a life of 200,000 molds, and the mold fee is 30,000-80,000 yuan (depending on the complexity). After dilution, the cost per piece is reduced by 60%-80%.

Q: Can mixed production processes be used?

A: Yes! For example, die-casting the main body + CNC finishing of key interface positions (such as threaded holes), taking into account both efficiency and precision.
