Waterproof treatment of parts in automobile assembly

1. Body seal

Body sealing is the first line of defense to prevent moisture from invading the interior of the car. By using high-quality sealing strip, adhesive tape or liquid sealant to seal the door frame, window frame and other parts, rainwater can be effectively prevented from infiltrating into the car from these gaps. In addition, for the parts of the underbody that are easily eroded by accumulated water, anti-rust primer is usually sprayed or plastic covering plates are used to protect them, so as to prolong their service life.

2. Electrical system protection

Automobile electronic equipment is very sensitive, once water enters, it may lead to short circuit or even permanent damage. To this end, the manufacturer will consider the waterproof problem at the beginning of the design. For example, wire connections are usually wrapped in waterproof materials; ECU (Engine Control Unit) and other key sensors will also be placed in a relatively dry position, and waterproof case will be installed outside to further improve the protection level.

3. Lamp sealing

Headlights, taillights and turn signals are not only an important guarantee for driving safety at night, but also a part of vehicle appearance design. In order to ensure that their functionality and aesthetics are not affected, all lamps need to undergo strict sealing tests. Generally speaking, the interior of the lamp will be filled with inert gas and maintain a certain pressure, and the outer surface will adopt a special waterproof coating, so that it can work normally without water leakage even in heavy rain.

4. Choice of seats and interior materials.

Although the seat itself is not directly threatened by external water sources, considering the occurrence of water splashing, it is particularly necessary to choose a fabric with good air permeability and rapid drainage as the seat fabric. In addition, the instrument panel, ceiling and other interior decoration parts should also be made of materials that are easy to clean and difficult to absorb water, thus reducing the possibility of mildew.

conclusion

To sum up, reasonable waterproof treatment can significantly improve the overall performance and user experience of the car. With the development of technology, the future cars will have a more advanced and perfect safety protection system, providing users with a more comfortable and comfortable driving environment.
