Frequently Asked Questions

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

Spot welding is more cost-effective and suitable for commercial-grade needs with medium shielding. Vacuum brazing provides superior mechanical strength, high-temperature resistance (up to 700°C), and maximum shielding performance for critical applications.

Q: Which materials are available for EMI shielded honeycomb panels?

We offer a wide range of materials including SUS304, SUS316L, Carbon Steel, Brass, Hastelloy X, and Aluminium to meet various corrosion and conductivity requirements.

Q: Can the cell size and frame shape be customized?

Yes, we provide customizable cell sizes ranging from 0.8mm to 50mm and offer frame shapes in "L", "C", and "H" types to ensure a perfect fit for your specific enclosure.

Q: What surface treatments are available for these panels?

Our available surface treatments include electroless nickel plating, white oxidation, electrophoresis, powder coating, tin plating, and various professional paints.

Q: Are these products compliant with environmental regulations?

Absolutely. Both our spot welding and high-temperature vacuum brazing technical processes are fully compliant with ROHS standards.

Q: Where are EMI/RF shielded honeycomb ventilation panels typically used?

They are widely used in data centers, marine vessels, vehicles, shielded chambers, racks, and any facility requiring airflow while preventing electromagnetic interference or information leakage.
