Frequently Asked Questions

Q: What is the difference between spot welding and vacuum brazing for EMI honeycomb?

Spot welding is a more cost-effective solution suitable for general commercial needs with medium shielding performance. Vacuum brazing offers superior intensity, higher shielding effectiveness, and can withstand temperatures up to 700°C with enhanced corrosion resistance.

Q: Which materials are best for high-corrosion environments in metal honeycomb manufacturing?

For high-corrosion environments, we recommend SUS316L, Hastelloy X, or adding surface treatments like electroless nickel plating or powder coating to enhance the protective layer.

Q: Can the cell size be customized for specific airflow requirements?

Yes, we offer a wide range of cell sizes from 0.8mm up to 50mm. The cell size directly impacts the balance between the amount of air ventilation allowed and the level of RF shielding provided.

Q: Are these EMI ventilation panels suitable for data center applications?

Absolutely. Our panels are widely used in data center racks, shielded cabinets, and closures to allow necessary cooling air while preventing electromagnetic interference and information leakage.

Q: What frame shapes are available for integration into existing equipment?

We provide customizable frame shapes including "L" type, "C" type, and "H" type to ensure a seamless fit into your specific chassis or enclosure design.

Q: Do your products comply with environmental standards?

Yes, both our spot welding and high-temperature vacuum brazing techniques are fully compliant with ROHS standards, ensuring they are safe for global industrial use.
