Frequently Asked Questions

Q: What is the main advantage of honeycomb vents over standard perforated sheets?

Honeycomb vents provide significantly higher electromagnetic shielding effectiveness (SE) while maintaining a much larger open area for airflow, preventing heat buildup in shielded enclosures.

Q: Can the cell size be customized for different RF frequencies?

Yes, we offer a wide range of cell sizes from 0.8mm up to 8mm. Smaller cell sizes generally provide better shielding against higher frequency interference.

Q: Which materials are available for the honeycomb core and frame?

We provide materials including SUS304, 316L stainless steel, carbon steel, aluminium, brass, and Hastelloy X to suit various chemical and environmental requirements.

Q: What is high-temperature vacuum brazing and why is it used?

Vacuum brazing is a joining process performed in a vacuum furnace. It creates an extremely strong, leak-proof, and electrically conductive bond between the honeycomb core and the frame.

Q: Do you offer surface treatments for corrosion protection?

Yes, we offer various coatings including electroless nickel plating, white oxidation, electrophoresis, powder coating, and tin plating depending on your application.

Q: How long does it typically take to manufacture custom EMI honeycomb panels?

For quantities below 50 pieces, the standard delivery time is 4-6 weeks. This ensures precision engineering and rigorous quality testing for each custom panel.
