Collaborating with GAC Group to Promote the Intelligent Upgrade of Automotive Seal Testing

1. On-Site Assessment Focused on Seal Testing Scenarios, Fruitful Technical Exchange

To facilitate the implementation of the partnership, WaFu Brothers dispatched a senior technical team to visit GAC Group on June 7 for an in-depth on-site assessment and technical exchange. The visit focused on key topics such as “seal testing technology applications,” “intelligent production line upgrades,” and “non-standard automation system integration,” specifically targeting the high-precision sealing requirements within the automotive manufacturing sector.

At GAC Group’s intelligent manufacturing base, the WaFu Brothers team held technical discussions with department heads regarding leak testing requirements for multiple key automotive components, including headlamp assemblies, battery packs, door modules, seat control units, and thermal management systems. Through comparative analysis of different product process characteristics, WaFu Brothers showcased its expertise in differential pressure testing, micro-leakage detection, vacuum methods, and other seal testing solutions.

In particular, for the new energy vehicle (NEV) sector, GAC Group has set higher requirements for the sealing performance of battery packs, charging ports, and electronic control units. In response, WaFu Brothers offered customized leak tester solutions that support multi-channel testing, rapid pressure range switching, and integration with MES systems, helping clients achieve automated, standardized, and efficient testing processes.

2. Building Non-Standard Automated Seal Testing Lines to Boost Manufacturing Efficiency

As automotive manufacturing becomes increasingly intelligent, traditional manual testing can no longer meet the demands of flexible production and consistent quality. Drawing from its mature experience in integrating non-standard automated seal testing lines, WaFu Brothers proposed several highly automated test unit designs. These integrate leak testers, sensors, data acquisition modules, and robotic loading/unloading systems to ensure stable testing and automatic result determination at high takt times—improving overall line efficiency and pass rates.

The WaFu Brothers team also gave a detailed demonstration of how seal testing equipment can be connected to a client’s MES system. Through real-time data acquisition, traceability systems, and anomaly alert mechanisms, they showed how to enable full-process quality monitoring and help customers build “data-driven” smart factories.

3. Strategic Cooperation Enters Deeper Waters, Accelerating Localization of High-End Testing Equipment

Since its founding in 2009, WaFu Brothers has been dedicated to seal testing technology R&D and equipment manufacturing. With over 16 years of experience in automotive, medical, new energy, and electronics high-end manufacturing sectors, the company’s core products include differential pressure leak testers, flow-based seal testers, and multi-station detection systems, widely applied in non-destructive testing of critical components.

This strategic cooperation with GAC Group signifies growing recognition of domestically produced seal testing equipment by mainstream automakers and lays a solid foundation for WaFu Brothers to further expand into the automotive industry supply chain.

4. Future Collaboration Directions

• Joint development of customized seal testing systems tailored to various vehicle structures;
• Co-establishment of demonstration production lines to promote the use of intelligent seal testers in vehicle manufacturing processes;
• Promotion of seal testing standards and construction of shared databases;
• Talent development for high-end testing to enhance overall industry capabilities.

5. Conclusion

This strategic partnership between WaFu Brothers and GAC Group is not only a powerful alliance but also a strong testament to China’s ability to localize core seal testing technologies in the “Made-in-China” ecosystem. At this crucial stage of intelligent manufacturing transformation, WaFu Brothers remains committed to technological innovation and customer-centric solutions, driving the broader application of domestic leak testers in the global high-end manufacturing market.

We firmly believe that through close collaboration with GAC Group, WaFu Brothers will take a solid and significant step forward in promoting independent and intelligent development of seal testing technologies in China’s automotive industry.
