Frequently Asked Questions

Q: What materials are best for corrosive environments in metal honeycomb manufacturing?

For highly corrosive environments, we recommend SUS316L or Hastelloy X, as they provide superior chemical resistance compared to standard carbon steel or aluminium.

Q: How does vacuum brazing improve the performance of EMI honeycomb panels?

Vacuum brazing creates a high-strength, seamless bond between the honeycomb cells and the frame, maximizing electrical conductivity and ensuring superior RF shielding effectiveness.

Q: Can these ventilation panels be customized for specific frame shapes?

Yes, we offer specialized frame types including "L" type, "C" type, and "H" type, along with fully customizable dimensions to fit your specific enclosure requirements.

Q: What surface coatings are available for EMI shielded honeycomb vents?

We provide a wide range of finishes, including electroless nickel plating, white oxidation, electrophoresis, powder coating, and tin plating to match your aesthetic and functional needs.

Q: Are the products compliant with environmental regulations like ROHS?

Absolutely. Both of our welding technical processes are fully compliant with ROHS standards, ensuring they are safe for use in global markets.

Q: Which industries typically use these EMI honeycomb ventilation panels?

Our panels are widely used in data centers, marine vessels, military vehicles, and any facility requiring high-efficiency air ventilation combined with RF shielding or information leakage prevention.
