Tungsten carbide seal rings are important components in industrial equipment, effectively sealing mediums such as gases or liquids.


Compared to unpolished tungsten carbide seals, polished tungsten carbide rings have a smooth and extremely hard protective layer on the surface. This smoothness and polished finish help improve its performance in hard and abrasive environments, further improving its leak-proof capabilities.

Polishing includes two steps: grinding and polishing. Langsun Carbide uses grinding tools or wheels to remove the surface material of the tungsten carbide seal, making its surface more planar. Then, polishing makes the surface smooth.


Polishing requires highly skilled operators as over-grinding or excessive polishing could alter the dimensions of the seal, impacting its use. But you can have complete confidence in Langsun Carbide's production technology.
