The foundation of any enterprise is inseparable from its products, and the life of a product is entirely dependent on its quality. Quality is not merely the result of production—it is an efficient, all-encompassing, and continuous interaction involving everyone in the organization, across all dimensions and at all times. It is a concentrated reflection of the company’s value orientation, technological capabilities, employee ethos, and management standards. Wanxiang has always adhered to the principle of “quality first,” continuously strengthening the cultivation of a quality-oriented culture, persistently innovating and refining quality management methods, and adapting to changing market demands and rising user expectations.

Quality awareness begins in the heart, and quality responsibility is put into practice through action. “Quality awareness begins in the heart” means cultivating a deep-seated awareness and understanding that stems from within—one that fosters a genuine appreciation for and reverence toward quality. “Quality responsibility is put into practice through action” requires translating this awareness into concrete actions: it calls for fulfilling one’s duties conscientiously at one’s post and working strictly according to established standards and procedures.

Zhang Jun, from the Wanxiang Qianchao Digital Intelligence Innovation Center, is responsible for handling all customer quality issues at Wanxiang Qianchao. Due to significant differences in specialized products and varying customer quality requirements, this position is characterized by high work pressure, complex tasks, and urgent deadlines for problem resolution. To promptly and efficiently address quality issues, prevent escalation of customer complaints, and ensure customer satisfaction, Zhang Jun often stays on-site at manufacturing facilities across various companies, analyzing problems, identifying root causes, and organizing corrective actions. With a strong focus on user service and his professional quality expertise, he has earned recognition and praise from customers.

While addressing client issues, he proactively took on responsibilities for process quality management, organized risk assessments and improvements for special processes such as heat treatment and welding, led the implementation of tiered review inspections and targeted corrective actions for exported products, and spearheaded the effective deployment of Wanxiang Qianchao’s QPR quality issue resolution tools. In 2024 alone, he conducted over 60 audits of various types and organized the compilation of more than 50 quality defect cases.

Quality Innovation, Digital Intelligence Together. In October 2023, Wanxiang Precision officially launched the development of its Quality Management Digital System (QMS). The system’s features address two major pain points—“system silos” and “time delays in inspection”—by integrating previously independently operated quality functions such as incoming inspection systems, precision measurement systems, inspection resource management, and metallographic testing into a unified platform. Additionally, the system is interconnected with other systems like SRM, WMS, and BPM, enabling seamless data exchange and integration throughout the operational process.

Through digital innovation based on quality fundamentals, we digitize the process data for all company inspections—including incoming material inspection, first and final inspections, metallographic inspection, precision measurement, physicochemical testing, and finished-product outgoing inspection—and implement closed-loop management by digitally tracking nonconforming products resulting from inspection anomalies, managing problem resolution, and maintaining a knowledge base of lessons learned.

Currently, the production line quality inspection and quality resource management modules have been launched and are in operation. The functions of other modules are currently undergoing intensive debugging and testing. Once the digital quality system is fully operational, it will help the company better meet the quality control requirements of “9N” customers, enhance internal quality management efficiency, and ensure that “quality and digital intelligence” go hand in hand.

Building the QC brand to win market trust. On the journey toward excellence in quality, the constant-velocity drive shaft manufacturer has demonstrated through concrete actions the essence of “Building the QC brand to win market trust.” Thanks to its outstanding product quality and customer service, the company has been recognized three times over the past two years as an “Outstanding Supplier” by a renowned Japanese automotive brand. This recognition not only affirms the manufacturer’s past achievements but also reflects users’ high regard for the QC brand’s premium-quality attributes.

To ensure the quality of delivered products, the Quality Department of the Constant Velocity Drive Shaft Plant took the lead in introducing the “9N” User SQGK Management System. After undergoing four training sessions and six rounds of coaching and diagnostics, the plant leveraged the 12 tools of the SQGK system to establish model work teams and enhance on-site management capabilities of manufacturing teams. Thanks to these efforts, the “9N” user’s diagnostic score for the Constant Velocity Drive Shaft Plant improved significantly and has remained at a high level, meeting the user’s requirements for entry and continued compliance.

Since mass production began in 2019, Nissan’s project has cumulatively supplied over 2.8 million drive shafts and has consistently maintained outstanding performance in terms of zero-kilometer defects, three-guarantee returns, and after-sales claims. Over the past 12 months, its rolling zero-kilometer defect rate has been 7 PPM, the three-guarantee return rate has been 172 PPM, and the after-sales claim rate has been 425 PPM—placing it far ahead of all other supplier performance metrics among automakers.

Upholding the quality baseline and safeguarding product safety—Wanxiang 123 has always adhered to the quality baseline, regarding product safety as the lifeline of the company’s development. The company boasts a professional quality team dedicated to meticulously maintaining every detail of product quality.

To deepen the upgrade of quality management processes, the Quality Department continuously enhances quality control across the entire product lifecycle—covering product design and development quality, supplier quality, production process quality, and after-sales service quality. We are making concerted efforts on multiple fronts: optimizing the procedures for handling production abnormalities and refining systems such as "spare parts management," "non-conforming product management," "production and line shutdown management," and "change-point management." In terms of raw material incoming inspection and in-process anomaly control, we have intensified both the initial quality checks and follow-up reviews to ensure that 100% of issues are effectively closed-looped. We strictly implement the 8D problem-solving methodology and take the lead in supervising the closed-loop rectification of quality issues reported by customers. Meanwhile, the company has established a Six Sigma culture, constantly identifying new opportunities for improvement and optimization. We also plan and carry out diverse quality activities, encouraging employees to submit improvement suggestions and innovative ideas, thereby fostering a positive and dynamic quality culture involving all staff members.

Thanks to the tireless efforts of the quality team, the company has effectively controlled its quality costs. From January of this year to date, the proportion of quality costs has dropped by 2.6% compared to the lowest level in previous years, the rate of customer complaints has decreased by 30%, and customer satisfaction has improved by 25%. The Wanxiang 123 quality team will continue to work hard, uphold the quality baseline, and safeguard product and service quality.

Quality is not merely a simple metric or a number—it is a spirit, a belief, and the very soul of a company. The process of building quality—from the procurement of raw materials and production processing to after-sales service—is not just a physical manufacturing process; it is also a process of shaping,凝聚ing, and nurturing spirit, culture, ideas, and consciousness. When we uphold a quality ethos that emphasizes rigor, meticulousness, and the relentless pursuit of excellence, our enterprise will possess enduring vitality.
