HMEMC designs, builds and installs high-performance shielded rooms and shielded machine rooms for EMI/EMC, TEMPEST and medical use. Buyers in United States use our systems for automotive and EV and other applications where shielding performance has to be provable, not promised.
HMEMC manufactures shielded room systems in Changzhou, Jiangsu, and has been supplying EMC and RF shielding equipment to overseas laboratories for years. For United States we work as high-performance shielded rooms and shielded machine rooms for EMI/EMC, TEMPEST and medical use, covering design, manufacture, shipping, installation and commissioning.

automotive and EV, aerospace and defence, semiconductor, medical, telecom. Shielded Room systems from HMEMC are typically used for:
FCC Part 15 and Part 18, ANSI C63.4 / C63.25 methodology and MIL-STD-461 for defence work. A2LA and NVLAP accredited laboratories are typical buyers.
US laboratories buy on documentation and uptime. They expect clear drawings, verified performance and spare parts availability.
FCL ocean freight to Los Angeles, Long Beach, Houston or Savannah; air freight for components. Shipments are packed for ocean or air freight, with drawings, packing lists and installation manuals prepared in English. Our site team travels for assembly, alignment and commissioning, and performance is verified by independent metrology laboratories before handover.
Yes. United States is an active market for us. Equipment is packed for ocean or air freight and shipped to fcl ocean freight to los angeles, long beach, houston or savannah or any port you nominate, with our site team available for installation and commissioning.
Standard components are typically ready in 6 to 10 weeks, and large chambers or shielded rooms are quoted with a project schedule. Installation time on site depends on the size of the room; a shielded room is usually assembled in a few days, while a full chamber takes longer.
Performance is specified per frequency band rather than as a single number, because shielding effectiveness falls as frequency rises. Small components such as vents are rated up to 100 dB at 40 GHz, and complete rooms are specified to the attenuation you need, then verified by third-party metrology laboratories.
We work either directly or through local partners, depending on what suits the project. Either way, engineering questions are answered by our own engineers, and installation can be carried out by our site team or supervised jointly with your contractor.
