Metallic Enclosures

Metallic enclosures incorporate multi-layered corrosion-resistant alloys with anodized or passivated surface treatments to prevent oxidation, even in highly saline or chemically aggressive environments. Precision-machined gasket interfaces ensure compliance with IP67, IP68, and NEMA 4X standards, effectively preventing moisture ingress, particulate contamination, and pressure differentials that could cause condensation buildup inside sealed systems. For applications requiring extended submersion resistance, enclosures undergo hydrostatic pressure testing to validate long-term sealing performance.

Technical Advantages

Our metallic enclosures are CNC-milled from aerospace-grade 6061-T6 or 7075-T6 aluminum and reinforced with internal structural ribbing to resist deformation under impact forces. Vibration-isolated mounting brackets and elastomeric damping interfaces reduce mechanical stress on enclosed PCBs and electronic modules, ensuring compliance with MIL-STD-810G, DO-160, and IEC 60068-2 standards. We offer hardened enclosures with AR500 or titanium alloy reinforcements engineered to withstand mechanical loads exceeding 100g acceleration profiles for applications exposed to extreme acceleration or ballistic threats.

Certain high-precision applications require enclosures that maintain vacuum integrity, inert gas sealing, or hermetic encapsulation to prevent exposure to contaminants or atmospheric degradation. Our enclosures are precision-machined to tolerances within ±5 microns, utilizing laser-welded seams and high-compression gasket materials to achieve helium leak rates below 10⁻⁶ mbar∙L/s, meeting NASA and ESA outgassing specifications. For high-altitude and space-based systems, our pressure-equalizing MEMS-based breather valves ensure that enclosures maintain structural stability during rapid pressure changes, preventing deformation or failure of internal components.
