From Water Testing to Leak Testing: Wafu Brothers Leading the Innovation in Seal and Waterproof Testing Technology
Published on: May 12, 2025
1. Limitations of Traditional Water Testing
In traditional manufacturing, water testing has been widely used as the primary method for seal testing due to its ease of operation and low cost. However, water testing has many limitations:
- It cannot provide quantitative leakage data, making it difficult to meet high-precision testing requirements.
- It may cause secondary contamination or damage to the product, especially unsuitable for electronic products.
- The testing process relies on manual observation, which is subjective and has poor repeatability.
As the demand for product sealing performance increases, traditional water testing is no longer sufficient to meet the quality control standards of modern manufacturing.
2. Advantages of Leak Testing
Leak testing, as a non-destructive testing method, is gradually replacing traditional water testing and becoming the mainstream technology for seal testing. Its main advantages include:
- High precision: Detects even tiny leaks with accuracy up to ±0.1 Pa.
- Non-destructive: Does not require product damage, making it suitable for finished product testing.
- Automation: Easy to integrate with production lines for automated testing, improving efficiency.
- Data-driven: Provides quantitative leakage data, facilitating quality traceability and analysis.
Leak testing has been widely applied in industries such as new energy vehicles, medical devices, and consumer electronics, becoming an important means of ensuring product quality and safety.
