Recently, several products have received authoritative provincial-level certifications, highlighting the strong technological capabilities and market competitiveness of Wanxiang’s related industrial companies in specialized industry segments.

Wanxiang Intelligent Manufacturing Co., Ltd., Wanxiang 123 Co., Ltd.

Zhejiang Province's First (Set)

The Zhejiang Provincial Department of Economy and Information Technology has released the list of first-of-its-kind (set) equipment certified for 2025 in Zhejiang Province. Wanxiang Intelligent Manufacturing Co., Ltd.'s "High-Freedom 'Zero-Hysteresis' Electronic Brake Angle Assembly" and Wanxiang 123 Co., Ltd.'s "High-Safety Semi-Solid Lithium-Ion Battery Cell Energy Storage System" have been certified.

The “High-Freedom ‘Zero-Drag’ Electronic Brake Caliper Assembly” features a domestically pioneered six-link steering knuckle, which reduces weight by 20%-30% and improves performance by 15%-25%, significantly enhancing vehicle steering responsiveness and handling stability. It innovatively adopts a two-dimensional optimized design for both the caliper assembly and the wheel hub unit, reducing drag torque from 1.2 N·m in comparable international products to just 0.5 N·m, thereby increasing range by 5% and contributing to energy conservation and emission reduction in new-energy vehicles. The product’s EPB electronic parking brake system boasts industry-leading intelligent features; its master-slave MCU dual-redundancy design reaches an advanced industry standard, and its sealing performance meets IP5K/IPX7 protection ratings. Key technical indicators have been verified by authoritative institutions and comprehensively outperform similar domestic products, earning the company four authorized invention patents. Currently, this product is being supplied to multiple major automakers and is supported by an intelligent production line, presenting broad market potential.

The “High-Safety Semi-Solid Lithium Battery Cell Energy Storage System,” independently developed by Wanxiang 123, builds upon semi-solid battery cells and incorporates a fully immersed pack design along with tiered fire-retardant liquid-cooling modules. It has successfully passed three authoritative tests—GB/T36276, UL9540A, and IEC62619—in one go. Moreover, the unit cost of this product is 23.5% lower than the average domestic price of liquid-based energy storage systems in 2024, and it has now entered successful mass production. Test data show that the temperature difference during system cycling can be controlled within 3℃, and the thermal runaway early-warning time is 10 minutes earlier than conventional temperature alarms. This system simultaneously meets the three core safety requirements—“source material safety, process monitoring safety, and end-of-line fire safety”—demonstrating the company’s leading technological prowess in the field of high-safety energy storage.

Wanxiang Intelligent Manufacturing Co., Ltd.

Zhejiang Province Manufacturing Single-Item Champion

The Zhejiang Provincial Department of Economy and Information Technology has released the first list of Zhejiang Province’s Manufacturing Single-Champion Enterprises, and Wanxiang Intelligent Manufacturing Co., Ltd. has been selected for its “New Energy Passenger Vehicle Chassis Brake System” product.

The chassis braking system is a critical safety component of a vehicle. It supports the vehicle’s entire weight and can quickly and effectively reduce the vehicle’s speed or bring it to a complete stop, ensuring driving safety. In emergency situations, it can also work in coordination with other vehicle systems to provide stability control and prevent loss of vehicle control.

The “New Energy Passenger Vehicle Chassis Braking System” features an EPB collaborative electronic caliper control system based on a dual-ECU architecture. Key performance indicators such as the hydraulic fluid volume required by the front and rear calipers, drag torque, and deformation levels all surpass industry benchmarks. This system represents a technological breakthrough in the field of 24V-powered, highly reliable, heavy-duty vehicle electronic parking brake systems. The product’s “closed-type torsion beam,” independently developed by our company, achieves a weight reduction of over 20% and exhibits significantly superior overall performance compared to similar products in the industry. It boasts exceptionally high torsional stiffness, ensuring both lightweight design requirements and robust product strength. In terms of aluminum alloy subframes, this product also delivers a weight reduction of more than 20%, filling a gap in China’s domestic processing technology for aluminum alloy structural components and making our company one of the few domestic suppliers capable of mastering this technology.

Qianchao Senwei Co., Ltd.

“Jiangsu Boutique”

The Jiangsu Provincial Administration for Market Regulation has released the list of products certified under the “Jiangsu Excellence” program for 2025. The precision forged component—injector housing for common-rail systems—produced by Qianchao Senwei Co., Ltd. has been awarded certification.

This product employs a flashless forging process, breaking through the traditional bottleneck of insufficient material utilization—typically below 70%—and boosting material utilization to as high as 98%. At the same time, the flashless process fully preserves the metal flow lines. Combined with a specially optimized tempering process, it successfully addresses the industry challenge of easy cracking in conventional forged parts after tempering, further enhancing the internal microstructural stability of the material and endowing the product with outstanding structural and mechanical performance. Thanks to precise process control, the dimensional tolerances for the forged components are tightly maintained within ±0.5 mm, ensuring perfect fit and compatibility with all injector assembly components and comprehensively meeting critical performance requirements such as structural strength, sealing, corrosion resistance, and heat resistance. The product has been granted an invention patent for “A Molding Die for Injector Bodies,” filling a technological gap in China’s precision forging of high-end injector housings. The company has established an intelligent manufacturing system, built dedicated production lines, and independently developed and designed an automated spray-cooling system, thereby raising the service life of molds to industry-leading levels and providing a solid foundation for efficient mass production.

Technological innovation is the fundamental driving force behind the leapfrogging of product iterations. All companies under Wanxiang will continue to focus on the technological pain points and core market demands in their respective niche segments, using independent R&D as the engine to boldly scale new heights in technology. Upholding a long-term perspective, we will make breakthroughs step by step and persist in our efforts over the long haul. Relying on lean manufacturing, we will refine and hone exceptional product quality. Through relentless dedication and continuous improvement, we will steadily build robust product capabilities.
