Metal Wire Mesh Gasket
Metal wire mesh gasket is a high-performance composite material that integrates electromagnetic
shielding, mechanical buffering, and environmental sealing functions. It is composed of precision
woven metal wire mesh (such as stainless steel 304/316L, Monel alloy, beryllium copper, etc.) and
elastic substrates (such as silicone, fluororubber, sponge) through special processes. The core
principle is to form a continuous conductive path through the high conductivity of the metal mesh,
effectively reflecting, absorbing, and attenuating electromagnetic waves, with shielding
effectiveness covering the frequency range of 10kHz to 40GHz; Meanwhile, the flexibility of
the elastic substrate enables it to tightly adhere to irregular gaps, fill machining tolerances, and
resist vibration, impact, and environmental corrosion. The product is widely used in electronic
devices, communication base stations, automotive electronics, aerospace, and military industries,
providing reliable electromagnetic compatibility (EMC) solutions for components such as chassis,
cabinets, connectors, and displays, while meeting IP67 dust and waterproof requirements. Its
design combines high performance and ease of use, and can be quickly installed through methods
such as adhesive bonding, mechanical snap fasteners, or welding, significantly improving the
stability and reliability of the equipment in complex electromagnetic environments.
Product Application
- Electronic devices: used for interface sealing of servers, switches, and industrial control cabinets to prevent electromagnetic interference from causing data transmission errors.
- Automotive electronics: installed in the gaps of the housing of modules such as onboard radar, camera, ECU, etc., to resist high-frequency interference from the engine compartment.
- Aerospace: As a sealing component for aircraft avionics systems and satellite communication equipment, it is suitable for extreme temperatures (-55 ℃ to+200 ℃) and strong vibration environments.
