On 31 July, a delegation of leaders from the Shenzhen Branch of China Quality Certification Centre (CQC) visited HIRAYS for inspection and guidance. The delegation was received and accompanied throughout by HIRAYS' senior management team. The two sides held in-depth discussions on quality management system development, innovation in testing technologies, and compliance certification for CCC-regulated products.

During the visit, the delegation toured HIRAYS' smart manufacturing workshop and R&D laboratories, walking through its standard assembly lines and precision testing zone. They conducted a comprehensive review of the company's deployment of smart manufacturing, advanced R&D and standardised testing capabilities, and spoke highly of HIRAYS' end-to-end quality control system and its independently developed, proprietary precision testing technologies.

HIRAYS' Director of the R&D Centre gave the delegation a detailed briefing on the company's in-house quadrupole mass spectrometry-based electrolyte leakage detection system. Developed specifically to address the new national standard for power banks and the associated CCC certification requirements, the system extends a mature electrolyte leakage detection approach proven in the traction battery sector into power bank manufacturing. It identifies trace electrolyte leakage with high specificity while effectively eliminating interference from vapours given off by adhesives and cleaning agents, fully satisfying the stringent compliance requirements of the updated rules.

The system has now been deployed at scale by leading consumer electronics brands and top-tier contract manufacturers in China and overseas. Validated through sustained volume production, it has earned broad market recognition for its operational stability, detection accuracy and compliance readiness.

The CQC Shenzhen Branch leaders commended HIRAYS for being among the first to overcome the key technical barriers in quadrupole mass spectrometry-based electrolyte leakage detection, for developing a sector-specific solution, and for bringing the technology into industrial application ahead of the market. They noted that HIRAYS' technical route and volume-production practice carry clear exemplary value for the industry: the solution is replicable and scalable, and offers an important technical reference for the power bank sector as it implements the new national standard and reinforces the baseline of product safety.

As China's authoritative quality certification body, CQC has long helped manufacturers improve quality and upgrade their capabilities by leveraging standards, certification and testing. This on-site visit and technical exchange identified concrete directions for refining HIRAYS' quality management system and provided authoritative, professional support for the company's technology iteration, compliance certification and commercial-scale expansion.

Looking ahead, HIRAYS will remain committed to its mission of "continuously creating value for customers through professional expertise", deepen collaboration with CQC, and draw on the institution's standards and certification resources to strengthen technological innovation and end-to-end quality control. The company will continue to advance in precision testing, applying robust, high-performance testing technologies to support compliant, high-quality growth across advanced manufacturing sectors, including consumer electronics and new energy.
