Key Technical Parameters

Parameter Specification Engineering Value
Base Material AL 6061-T6 Superior mechanical strength and machining precision compared to die-cast aluminum.
Surface Finish Conductive Oxidation (Chemical Film / Alodine) Strictly controlled at 5-8μm thickness to ensure excellent electrical conductivity and optimal EMI/RFI shielding.
Corrosion Resistance Passed 168 Hours Salt Spray Test (NSS) Exceeds standard chemical film requirements, guaranteeing durability in harsh outdoor and marine environments.
Dimensional Accuracy Critical Dimensions Strictly Controlled SPC (Statistical Process Control) applied to ensure batch-to-batch consistency.
Threaded Holes High-Density Precision Array (M2/M2.5/M3) Positional tolerance within ±0.05mm for seamless PCB and cover assembly.

Core Product Features

Optimized for EMI Shielding

The Conductive Oxidation finish is precisely controlled to a thickness of 5-8μm. This ensures excellent electrical continuity across the entire surface, providing a reliable low-resistance ground path for superior EMI/RFI shielding effectiveness.

High-Density Precision Machining

Capable of machining complex patterns of threaded holes (M2/M2.5/M3) on thin walls without causing deformation. We utilize Forming Taps to create stronger, more durable threads in aluminum, preventing stripping during repeated assembly.

Enhanced Corrosion Resistance

While standard chemical films often pass 48-96 hours of salt spray, our advanced process guarantees 168 Hours of Salt Spray Resistance (NSS). This makes our enclosures exceptionally suitable for outdoor telecommunications and marine applications.

Complex Cavity & Pocket Milling

Expertise in deep pocket milling with tight depth tolerances (e.g., 11.6±0.1mm) to accommodate specific internal components. We ensure clean internal corners and edges, with deburring performed per standard Q/YS 104.7 to prevent any potential wire damage.

Manufacturing & Quality Control Process

1
Material Certification 100% Genuine AL 6061-T6 material with full Traceability Reports.
2
CNC Machining 4-axis/5-axis simultaneous machining to complete side holes, tapped holes, and complex cavities in a single setup, ensuring high positional accuracy.
3
Surface Treatment Control Dedicated production line for conductive oxidation; coating thickness is verified on every batch using the Eddy Current method.
4
Final Inspection

  • CMM Measurement Comprehensive verification of all “Critical Dimensions” (marked with boxes on the drawing).
  • Thread Gauging 100% inspection of all threaded holes using GO/NO-GO gauges.
  • Visual & Salt Spray Test Final visual inspection and regular salt spray testing to validate corrosion resistance.
