Much radio frequency infrastnxture equipment is required to mount in an EIA compatible relay rack or cabinet. In many of the relatively low vol- ume products developed for two way radio infra- structure equipment, very little tooling dollars are available and yet low piece part cost is required. Traditionally, EIA rack mount compatible chassis' are made from short run fabricated/stamped sheet metal, or die casting technology. These designs are typically structurally sound with the added benefit of EMI/RFI shielding. For certain applications, extremely low volumes make the tooling dollars required for custom stamped or die cast designs prohibitive. A short run fabricated sheet metal enclosure is a feasible alternative but would result in a high piece part cost due to the more labor inten- sive nature of its fabrication. An attractive and unique alternative is extrusion technology.
