On the development path of aluminum boxes, in addition to the conventional features of being sturdy, durable, beautiful, and elegant, some instrument aluminum boxes used for storing precision equipment have even higher requirements, such as shock absorption, waterproofing, and so on. Today, let''s take a look at the waterproof sealing of aluminum boxes. The waterproofing of aluminum boxes depends on two aspects: the design of the box body and the sealing rubber strips.
Box Body Design:
The design of the aluminum box has a very significant impact on its sealing performance. The box body at the supporting hinges and hinges should be completely closed. This requires manufacturers to have stricter control over precision during the production process.

Sealing Rubber Strips:
After the box body is closed, there will inevitably be some gaps between the metals. These gaps need to be sealed with rubber strips. Adding a sealing rubber strip around the opening of the aluminum box can achieve a better sealing effect.
Appendix: Waterproof Grade
The waterproof grade of aluminum boxes can be divided into the following categories according to industry standards:
0: No protection
1: Water droplets dripping onto the shell have no impact
2: When the shell is tilted at an angle of 15 degrees, water droplets dripping onto the shell have no impact
3: Water or rainwater splashing onto the shell from a 60-degree angle has no impact
4: Liquids splashing onto the shell from any direction cause no harm
5: Washing with water causes no harm
6: Can be used in the environment inside the cabin
7: Can withstand immersion in water (at a depth of 1m) for a short period of time
8: Can be immersed in water for a long time under a certain pressure
Generally, the waterproof grade of aluminum boxes is mostly above level 4. For aluminum boxes with waterproof requirements of level 7 or 8, you can call the manufacturer to customize them.
