EMI/RFI Shielding Enclosures

Lancaster Metals Science is a leading manufacturer of EMI / RFI shielding enclosures. Processing a wide variety of metals including steel, nickel-iron alloys with high permeabilities, brass, copper and nickel silvers assures that Lancaster Metals can produce an enclosure that will perform to your specific shielding requirement. In addition, Lancaster Metals offers a wide range of plating options including tin, tin-lead and silver to enhance the solderability of the base metal.


One of the benefits of photochemically machining a shielding enclosure is the possibility of incorporating precisely etched bend score lines in the flat blank design to facilitate the final forming of the enclosure. Such score lines, while adding no cost or additional time to the fabrication of the flat blank, allow the enclosure to be precisely formed without the need for any additional form tooling — thus avoiding the costs and delays associated with such tooling.

Variety of enclosure designs including single piece enclosures, shields with removable covers and multi-piece enclosures that feature internal walls.

For enclosures less than 120 mm by 32 mm, Lancaster Metals also offers tape and reel packaging.

EMI/RFI Shielding Enclosures
Various nickel silver enclosures with removable covers. “A” shows covered enclosure which is shown without its cover in “B”, revealing internal dividers that are soldered in place.
“C” & “D” show enclosures with covers that are secured with formed spring fingers. All these enclosures are also shown inverted and in greater detail.
