Custom Cell Size 0.8-3mm Honeycomb Seal Ring for Aero-engine
The Custom Cell Size 0.8–3 mm Honeycomb Seal Ring for Aero-Engine is a high-temperature, abradable sealing component designed for compressor, turbine, combustor, and labyrinth seal applications. It is manufactured with a precision hexagonal honeycomb core brazed or welded to a metallic backing ring.
The honeycomb cell size can be customized from 0.8 mm to 3.0 mm to optimize leakage control, rub tolerance, thermal stability, and service life. This product is suitable for OEM and retrofit aero-engine sealing systems.

Applications:
· Aerospace & Aviation Sealing: Ideal for aircraft jet engine compressors and turbine shrouds.
· Power Generation Gas Turbines: Used in combined-cycle power plants to minimize parasitic steam leakage, which reduces average heat
consumption by approximately 5 grams per kilowatt-hour of standard coal.
· Industrial Steam Turbines: Enhances rotor stability and dehumidification at blade tips, protecting components from moisture erosion.
· Wind Tunnel & Compressor Flow Straighteners: Ensures laminar airflow and reduces aerodynamic losses in high-speed test facilities.
· EMI/RFI Shielding: The metallic honeycomb structure also acts as an electromagnetic interference (EMI) shielding vent in sensitive electronic enclosures.
Advantages
| 1 | Very low cross coupling |
| 2 | Higher direct damping that labyrinth seals |
| 3 | More forgiving than labyrinth seals in the event of a rotor-stator rub |
| 4 | Variety of materials available to serve a wide range of applications |
| 5 | Capable of sustaining higher temperatures than conventional labyrinth seals |
