What The MuShield Company does
The MuShield Company, founded in 1989 in Londonderry, New Hampshire, is a privately held, family-owned precision manufacturer specializing in custom magnetic shielding and sheet metal fabrication. The company designs and produces custom magnetic shields from high-permeability nickel-iron alloys — principally mumetal, HyMu 80, Cryoperm, and silicon iron — for applications where stray magnetic fields would compromise sensitive electronics, instruments, or imaging systems. It also runs an integrated precision sheet metal fabrication operation that includes laser cutting and welding (Trumpf 5-axis TruLaser Cell 3010, IPG LaserCube, Amada C-1500b), CNC machining, in-house tooling design, and a 12-inch Cincinnati Hydroform Press operating up to 15,000 psi. In-house hydrogen heat treating at 2,100°F in a dry hydrogen atmosphere is performed in retort sizes up to 20" x 20" x 40", yielding high-permeability shielding components.
MuShield's proprietary technology platform centers on seamless mumetal tubing produced via advanced metal extrusion — claimed to be the only commercially available offering of its kind globally, with diameters from 0.080 to 2.65 inches and lengths up to 20 feet. Engineering and qualification are supported by ANSYS FEA simulation, Autodesk Inventor CAD, and Magneto software, alongside formal AS9100D, ISO 9001:2015, ITAR, and CMMC Level 1 certifications that qualify the firm for aerospace and defense prime-contractor work.
The company sells through a consultative, direct enterprise sales motion: application engineers work alongside customer engineers on RFQ-driven, quote-based custom projects, supplemented by e-commerce ordering of standardized MSK Tech Kits ($179) and raw material sales. Revenue streams include custom magnetic shielding fabrication, precision sheet metal fabrication services, contract hydrogen heat treating, and material sales. Customers are concentrated in aerospace & defense (Boeing, Honeywell, Raytheon, Northrop Grumman, BAE Systems, NASA, JPL), medical device manufacturing (GE Medical, St. Jude Medical), and research (Smithsonian Astrophysical Observatory), with international reach via a 25-year exclusive representation partnership with Silram Group Ltd. in Israel.
