Aluminum Machine Enclosures

In electronics and manufacturing, an enclosure is a protective housing that contains, organizes, and shields electronic or mechanical components. Aluminum machine enclosures like rack mount chassis provide structural support, EMI shielding, and environmental protection for sensitive equipment in industrial, military, and commercial settings.

A Type 3 enclosure is rated for outdoor use and designed to protect against rain, sleet, and wind-blown dust. In the context of MIL-C-5541E Type I Class 3, it refers to a chemical film finish applied to aluminum surfaces for corrosion protection — commonly used in military and government electronics enclosures.

Ron Nunes rack mount chassis systems are available in heights ranging from 1U to 9U (1¾" to 15¾"), with additional options at 17½", 19¼", and 21". This wide range accommodates diverse electronics packaging requirements from compact single-board systems to larger multi-component installations.

Standard depths available include 8", 14", 20", and 26 inches. Custom depths are also available upon request, allowing OEMs and systems integrators to match chassis dimensions precisely to their component layouts and rack infrastructure specifications.

The primary chassis material is aluminum sheet 0.125" thick, Alloy 6061-T6 per QQ-A-250/11 and ASTM B209. Chassis plates use Alloy 5052-H32, and handles are extruded aluminum Alloy 6061-T5. Stainless steel options and MIL-C-5541E gold chemical film finishes are also available for military-grade applications.
