The car door seal strip is mainly responsible for the sealing work of the car door. It is usually installed at the edge of the car door, closely attached to the body, and looks like a strip or circle of rubber, silicone or other materials, soft and elastic.
If you drive out on a rainy day without the sturdy defense line of the car door seal, rainwater will flow freely into the car through the gaps in the door. Imagine if the seats and floor mats are all wet, not only is it extremely uncomfortable to ride, but long-term accumulation of water can also easily breed mold in the car and emit unpleasant odors. Even worse, once rainwater comes into contact with the electronic circuits inside the car, problems such as short circuits and malfunctions can occur at any time, posing a serious threat to driving safety.
And high-quality car door seals, with their close fitting characteristics to the body of the car, are like installing a waterproof gate on the door, which can effectively block rainwater intrusion and ensure that the interior of the car remains dry and comfortable at all times.
On busy city roads or high-speed highways, the noise from the outside world, the honking of other vehicles, and the roar of tires rubbing against the ground are all heard. If the sealing of the car door is poor, these noises will enter the car without obstruction, making the driver and passengers shout loudly for communication.
After long-distance driving, the ears will be tortured and the fatigue will intensify. But with the car door seal strip, things are very different. It uses its own flexible material to fill the gaps in the door, isolating most of the external noise and mechanical noise generated during vehicle operation, creating a relatively quiet and comfortable small space inside the car, allowing for comfortable conversations, listening to music, and broadcasting.
Daily driving, especially near dusty construction sites, unpaved roads, or areas with strong sandstorms, is filled with a large amount of dust and sediment particles in the air. If the car door seal is not tight, these tiny but annoying dust particles will easily enter the car with the airflow and fall on the dashboard and seats.
Within a few days, the car will become dusty and difficult to clean. Moreover, inhaling dust into the human body can also affect health. At this moment, the car door seal is like a loyal guardian, firmly blocking dust particles outside the car with a fine fit, ensuring the fresh and clean air inside the car to the greatest extent possible, and making every breath worry free of "dust".
In the scorching summer, the sun outside the car is scorching hot, and the ground temperature is soaring. If the car door seal is not good, hot air will continuously pour into the car, greatly reducing the cooling effect of the air conditioning. It's like being in a steamer, and no matter what, it won't cool down; In the cold winter of December, the piercing cold air will take advantage of the gaps and quickly dissipate the heating inside the car, making people shiver with cold.
The car door seal strip plays a magical role in insulation. In summer, it prevents hot air from penetrating and assists the air conditioning in keeping it cool; In winter, it keeps the interior warm, reduces heat escape, and maintains a pleasant temperature throughout the year, greatly improving driving comfort.
Although the main function of the car door seal is not to provide collision prevention, it can still be useful in the event of a minor collision or external impact on the vehicle door. Its soft and elastic material can instantly cushion some of the impact force, reduce the collision force between the car door and the body frame, avoid excessive deformation of the car door due to hard collision, and thus protect the safety of passengers in the car to a certain extent, adding an invisible auxiliary guarantee to passenger safety.
