Metal Shielding Wire Mesh

Shielding net is an electromagnetic protection device made of metal materials such as copper and tin

plated copper wire as the core. It uses a precise metal weaving structure to reflect, absorb, and convert

electromagnetic waves, effectively isolating external electromagnetic interference and preventing

internal signal leakage. This shielding network exhibits excellent shielding effectiveness in the frequency

range of 10MHz to 3GHz, and is widely used in places with strict electromagnetic environment requirements

such as radar stations, hospitals, and laboratories, ensuring stable operation of equipment and reducing

electromagnetic radiation risks. Its weaving density exceeds 80%, adopting an optimized weaving

angle of 30-45 °, endowing the product with the dual characteristics of non-magnetic and wear-resistant,

and supporting single or multi-point grounding methods, flexibly responding to the shielding needs of

different frequency bands. In addition, some models of shielding nets also have a light transmittance

of 50% -70%, which can perfectly adapt to scenarios that require both ventilation and light transmittance,

such as instrument display windows and chassis ventilation ports, achieving the unity of functionality

and practicality.

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.
• In the field of new energy, it is used for electromagnetic shielding of photovoltaic inverters and energy storage battery packs to ensure the safe operation of equipment under high voltage and high current conditions.

Product characteristics
