Types of Automotive Door Seals
Automotive door seals come in various types, each serving a specific purpose. Below is a comparison table of the different types of automotive door seals.
| Type | Description | Material Used |
|---|---|---|
| Primary Door Seal | Mounted on the door, acts as the first barrier against elements. | EPDM Sponge Rubber |
| Secondary Door Seal | Mounted on the vehicle body, enhances sealing performance. | EPDM Solid Rubber + Metal Carrier |
| Glass Run Channel | Stabilizes window glass during movement, mounted inside the door frame. | EPDM Solid Rubber + Flock |
| Hood Seal | Seals between the hood and the vehicle body, preventing air and water entry. | EPDM Sponge Rubber |
| Trunk Seal | Prevents air and water from entering the trunk compartment. | EPDM Solid Rubber + Metal Carrier |
| Sunroof Seal | Prevents dust and moisture penetration into the vehicle. | EPDM Solid Rubber |
Primary Door Seal
The primary door seal is attached to the vehicle door using self-adhesive tape or plastic retaining clips. It acts as the first sealing barrier between the vehicle door and body, working in conjunction with the secondary door seal for optimal performance.
Secondary Door Seal
The secondary door seal fits into the vehicle body panel and plays a major role in isolating the vehicle cabin from outside elements. It also buffers impacts from the door’s opening and closing, ensuring easy closing and better sealing.
Glass Run Channel
The glass run channel is mounted to the insides of the automotive door window frame, allowing the movable window glass to slide freely. It stabilizes the glass during movement and is often covered with flock or coated with abrasion-resistant polyurethane (PU) to minimize friction.
Hood Seal
Hood seals act as a sealing barrier between the hood and the front portion of the vehicle body. They are essential for maintaining the engine compartment’s integrity against external elements.
Trunk Seal
The trunk seal fits into the body panel around the trunk, preventing air, water, and debris from entering the trunk compartment. This seal is crucial for maintaining the cleanliness and functionality of the trunk area.
Sunroof Seal
Sunroof weatherstrips prevent the penetration of dust and moisture into the vehicle, ensuring a comfortable driving experience.
Conclusion
In summary, automotive door seals are essential components that enhance the performance and comfort of vehicles. They are designed to withstand various environmental conditions while providing effective sealing against water, air, dust, and noise. Manufacturers like Hebei Shida Seal Group, Letu Automotive, and Ruyi Rubber offer a wide range of high-quality automotive weatherstrips and seals tailored to meet diverse automotive needs.
