To be a valuable global supplier
for metallic honeycombs and turbine parts
The honeycomb gas seal is composed of a back plate (a base plate facing the casing wall) and a metal honeycomb (a brush cross section facing the tip of the turbine rotor blades) brazed together. This design effectively reduces the air passage clearance between rotating components and improves engine efficiency. Therefore, it is widely used in the cold and hot ends of gas turbines and aero engines.
The primary reasons for using honeycomb seals as rotor blade end seals (friction seals, wear-resistant seals, etc.) are twofold:
(1) To provide a gas path seal, preventing hot engine gas from bypassing the turbine rotor blade ends;
(2) To provide a sacrificial surface on which the rapidly rotating blades will rub.
Achieving these objectives results in higher fuel efficiency and extended service life for all rotating components.
