HMEMC designs, builds and installs brazed aluminium honeycomb waveguide vents that keep airflow while holding attenuation. Buyers in South Africa use our systems for mining and other applications where shielding performance has to be provable, not promised.
HMEMC manufactures honeycomb waveguide vent systems in Changzhou, Jiangsu, and has been supplying EMC and RF shielding equipment to overseas laboratories for years. For South Africa we work as brazed aluminium honeycomb waveguide vents that keep airflow while holding attenuation, covering design, manufacture, shipping, installation and commissioning.

mining, power utilities, telecom, automotive assembly, defence. Honeycomb Waveguide Vent systems from HMEMC are typically used for:
SANS and ICASA requirements with CISPR/IEC based test methods; SANAS accredited laboratories are key customers.
African buyers need a supplier who stays involved after delivery, including installation, commissioning and spare parts.
Durban and Cape Town ports; installation and commissioning support on site. 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. South Africa is an active market for us. Equipment is packed for ocean or air freight and shipped to durban and cape town ports 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.
