EMI / EMC Shielded Aluminum Enclosure Machining Capability

Precision CNC Machined EMI / EMC Shielded Aluminum Enclosures

We specialize in high-precision CNC machining of EMI / EMC shielded aluminum enclosures, designed for applications where electromagnetic interference control, structural integrity, and dimensional accuracy are critical. Our machined shielding housings are widely used in RF communication, aerospace electronics, test & measurement systems, industrial control, and high-reliability electronic equipment.

Our EMI / EMC enclosures are fully machined from solid aluminum billets, ensuring superior precision and shielding continuity compared to die casting.

Core Machining Capabilities

• 3-Axis, 4-Axis CNC Milling

• Multi-face machining with precise re-fixturing

• Deep pocket milling and multi-level internal cavities

• Dense hole arrays for electronic modules and connectors

• Precision sealing grooves and mounting interfaces

• Drilling, tapping, counterboring, and thread milling

Critical Machining Focus

• High flatness and parallelism on mating surfaces

• Tight tolerance control on enclosure joints

• Burr-free edges for reliable grounding and assembly

Typical tolerance capability:

±0.01 mm, tighter tolerances available upon request.

Surface treatment plays a critical role in electromagnetic shielding effectiveness. We offer multiple options based on application requirements:

• Chemical Conversion Coating (Chromate / Alodine)

Preserves surface conductivity for grounding and EMI continuity

• Selective anodizing (non-shielding areas only)

• Conductive anodizing (specialized applications)

• Conductive coating (silver, nickel, copper-based)

• Laser marking for traceability

⚠️ Thick standard anodizing is not recommended for EMI contact surfaces unless conductivity is preserved.

Each shielding enclosure undergoes strict quality inspection:

• CMM (Coordinate Measuring Machine) dimensional inspection

• Flatness and sealing surface verification

• Thread and hole position accuracy checks

• Visual and surface integrity inspection

• Assembly trial fitting upon request

Our inspection process ensures mechanical precision and reliable electromagnetic shielding performance in demanding environments.
