The definition and importance of leakage testing of zinc die-casting parts

Leakage testing of zinc alloy die-casting parts refers to using professional testing technology to identify defects such as tiny pores, cracks and poor interface sealing in zinc alloy die-casting parts to ensure the sealing and reliability of the product during use.As automobiles become lighter and electronic products become more complex, the sealing quality of die-cast zinc parts has become a key factor affecting overall performance.

According to "GB/T 2828-2012" (China's National Sampling Inspection Standard) and international standards such as ISO 20485, leak testing methods usually include gas leak detection, vacuum detection and water pressure testing.Data shows that after using high-precision leak testing equipment, product repair rates can be reduced by more than 30%, significantly reducing corporate production costs and after-sales risks.

For example, an automobile engine parts supplier introduced helium leak detection technology to achieve a detection speed of 10 frames/minute, ensuring the sealing performance of parts and meeting the strict requirements of high-end engines for die-cast zinc parts.

Advanced leakage testing technology and application of die-cast zinc parts

Currently, commonly used leakage testing technologies for die-cast zinc parts include gas leakage method, pressure decay method, vacuum method and fluorescence penetrant detection method.Among them, the gas leakage method is widely used in the detection of zinc alloy parts with complex structures due to its high sensitivity and fast detection speed.

For example, using helium as a tracer gas and using a mass spectrometer to detect trace leaks, the minimum detection sensitivity can reach 10^-9 Pa·m³/s, providing guarantee for high-precision die-cast zinc parts.The pressure decay method monitors the pressure changes in the test chamber and is suitable for batch testing and has high efficiency.According to market research, more than 65% of zinc alloy die-casting manufacturing companies use a combination of pressure attenuation and gas leakage to improve detection accuracy.

At the industry application level, products such as electronic connectors and precision valves that require extremely high sealing performance give priority to helium or nitrogen leakage testing solutions to ensure safety and corrosion resistance.

Key international and domestic standards for leakage testing of zinc die-casting parts

Standardized management is the basis for ensuring the testing quality and industrial applicability of zinc die-casting parts.At present, the mainstream leak test-related standards cover design specifications, test procedures and data analysis methods.Among them, ISO 20485:2017 proposes clear test methods and qualification standards for the sealing performance of castings.

Chinese industry standards such as Q/320505 SSH 002-2020 specify the test conditions, equipment parameters and improvement directions for the air tightness testing of die-cast zinc parts.According to data from a key die-casting enterprise, the standardization of the leak detection process under the guidance of standards has increased the detection rate by about 10%.

At the same time, in order to adapt to the development of intelligent manufacturing, some companies combine IoT technology to realize real-time collection and analysis of leakage test data, and promote dynamic updates of standards and quality tracking.

Future trend: Leak testing technology in the direction of intelligence and green environmental protection

With the rise of Industry 4.0 and green manufacturing concepts, leakage testing technology for zinc die-casting parts has also shown a trend of intelligent and environmentally friendly development.The combination of smart sensors and big data technology can realize automatic detection and fault warning, greatly improving detection efficiency and accuracy.According to statistics, after the application of the intelligent detection system, the test time is shortened by 25% on average and the data processing error is reduced by 15%.

The promotion of environmentally friendly detection agents and non-destructive detection technology has reduced the environmental pollution caused by traditional solvent detection.With the help of laser scanning, X-ray imaging and computer vision, companies can reduce equipment energy consumption and chemical waste generation while ensuring detection accuracy, and meet the requirements of sustainable development.

Enterprise application scenarios are increasingly enriched, such as the leakage test of die-cast zinc parts for new energy vehicle battery casings, which integrates automated manipulators and intelligent control systems to achieve no manual intervention in the entire process, promoting industry upgrading.

Practical suggestions: Key points to improve the leakage testing effect of die-cast zinc parts
