Automotive Sealing Components Classification

Door Seals: Installed at the junction of the door and the body, made of elastic rubber. They achieve waterproofing and dustproofing by filling gaps through deformation, while also blocking external noise from entering the cabin. They also cushion vibrations from metal-to-metal collisions when the door closes.

 

Window Seals:Surrounding the edge of the window glass, made of high-temperature resistant and anti-aging rubber. Maintaining elasticity within a temperature range of -40℃ to 120℃, they ensure a complete seal when the window is closed, providing dual functions of preventing rainwater penetration and reducing wind noise.

 

Engine Compartment Seals:Made of high-density elastomer material, installed at the junction of the engine compartment and other areas of the body. They effectively isolate oil splashes and mechanical noise generated by engine operation, and prevent moisture from seeping into critical electrical systems through gaps.

 

Sunroof Seals:Located on the edges of the sunroof rails and frame, made of highly elastic rubber. A deformation compensation mechanism provides all-weather waterproofing, maintaining a closed state even at speeds exceeding 100km/h, significantly reducing wind noise at high speeds.
