Jiangsu Real Longding Industrial Co., Ltd.

Jiangsu Real Longding Industrial Co., Ltd. is a wholly-owned subsidiary of Shanghai Real. It is a high-tech enterprise integrating automotive metal materials, sealing, and advanced manufacturing, and is a global leader in automotive intelligent brake valve bodies and automotive turbocharger compressor impellers. Real Longding has achieved a compound annual growth rate of 35% in revenue over the past three years and is expected to maintain rapid growth over the next five years, with a Pre-IPO plan. The company's main business includes ONE-BOX valve bodies, ASU valve bodies, ESC valve bodies, ABS valve bodies, turbocharger compressor impellers, aluminum-ceramic brake discs, and various machined and anodized products. Its valve bodies have received support from the Innovation Fund Program of the Ministry of Science and Technology.

Automotive safety intelligent braking ONE-BOX valve body

Supported by the Innovation Fund Program of the Ministry of Science and Technology of China; independently developed new aluminum alloy materials with 40% higher performance and 1-micron precision; equipped with 90 Japanese-imported dual-pallet horizontal machining centers, more than 160 vertical machining centers, 20 high-pressure cleaning units, and comprehensive post-processing capabilities including cleanliness testing; annual production capacity of 3.6 million pieces.

Automotive & Motorcycle ABS/ESC Valve Bodies

The ABS precision machining plant is mainly engaged in the production of automotive ABS components. Its process flow—from machining, deburring, laser marking, ultrasonic cleaning, and high-pressure cleaning to packaging and shipping—is completed in a single integrated operation. It is equipped with 150 Japanese-imported dual-pallet horizontal machining centers, more than 60 vertical machining centers, and comprehensive post-processing capabilities including dimensional, profile, burr, and cleanliness inspection.

Air Suspension ASU Valve Body

Supported by the Innovation Fund Program of the Ministry of Science and Technology of China; independently developed new aluminum alloy materials with 40% higher performance and 1-micron precision.

Turbocharger compressor impellers, aerospace blisks

Equipped with more than 50 imported dual-spindle machines from Germany, including SW and Chiron. By early 2024, cumulative deliveries had reached 10 million pieces, with an annual production capacity of 4.5 million pieces. A newly built 13,000 ㎡ plant was put into production in early 2024. The company possesses 3D modeling technology, surface optimization technology, and five-axis program calculation and editing capabilities. The impellers feature 1-micron precision, a rotational speed of 5,000 revolutions per second, a linear speed of 520 meters per second, and reliable operation for 10,000 hours under alternating temperature environments. Projected production capacity for 2026 is 8 million pieces.

Aluminum-ceramic composite materials

The first domestic enterprise to adopt the stir casting process. Real's independently developed rail transit brake discs have entered small-batch supply to Knorr-Bremse, a global leader in rail transit. Advantages of aluminum-ceramic composite rail transit brake discs and automotive brake discs: light weight (one-third of cast iron), wear resistance (8 times that of cast iron), fast heat dissipation (3 times that of cast iron), high strength, corrosion resistance, high friction coefficient, energy saving and environmental protection, and brake performance free of judder and noise. Annual production capacity is 200,000 automotive aluminum-ceramic brake discs and 30,000 metro brake discs.

Aluminum alloy forgings

The plant is equipped with Japanese-imported vertical machining centers as well as press-fitting, air-tightness testing, and other equipment, and performs precision machining of castings such as bracket products and hydraulic valve bodies. Major customers include ACTUANT (domestic and international), Knorr-Bremse, SAIC Volkswagen, and others.

Precision machined parts

Process parameters of the anodizing line are automatically monitored. The required chemicals are automatically analyzed and automatically added, ensuring stable production on the anodizing line. The anodizing line has an annual production capacity of 3 million pieces for valve bodies and master cylinders, and 5 million pieces for 1-box valve bodies.

Jiangsu Real Longsheng Impeller Technology Co., Ltd.

Jiangsu Real Longsheng Impeller Technology Co., Ltd.'s intelligent brake actuator (ESC-HCU) has been awarded a major national special project for core technology breakthroughs in intelligent automotive chassis. The company has process R&D capabilities in the design and manufacturing of electronic stability system HCU products (ABS-HCU, ESC-HCU, and One-box solenoid valves — under development). Vehicles equipped with its products are exported to multiple countries. In 2021, it became the first company in China to achieve localized mass production of ESP-HCU, a project that addressed a bottleneck in core technologies for new energy vehicles for the National Development and Reform Commission. Longsheng's main business covers automotive intelligent braking system actuators (ESC-HCU) and linear solenoid valves, serving the automotive, embodied intelligence, and humanoid robot sectors.

 

As a major domestic manufacturer of HCUs, the company offers low costs, short production cycles, and complete new automotive HCU assembly solutions. Its annual production capacity for automotive electronic stability control system HCUs is 1.5 million sets.

Solenoid Valve Series Products

The servo electric presses used on the solenoid valve production line feature Kistler 100% assembly process monitoring (displacement & force). 100% testing of external leakage with 200 bar high-pressure nitrogen; 100% in-line inspection of stroke, air gap, and electrical response characteristics; i_dp_q linear control of USV solenoid valves; and in-line monitoring of current values corresponding to 50/100 bar. Annual production capacity of linear solenoid valves is 15 million units, making the company a leading enterprise in this domestic market segment.

Integration Capabilities

Brake-by-wire systems are one of the key technologies of intelligent chassis. They replace traditional vacuum boosters and vacuum pumps with electric motors to achieve faster and more precise braking control. Brake-by-wire technology is particularly suited to the needs of electric vehicles, since EVs lack a stable vacuum source, and brake-by-wire avoids the drawbacks of adding a vacuum pump, such as lightweighting challenges, noise issues, and short service life. In addition, brake-by-wire enables energy recovery for new energy vehicles, improving driving range.

As a national-level specialized, refined, distinctive, and innovative (SRDI) "Little Giant" enterprise, Jiangsu Real Longding Industrial Co., Ltd. has been deeply engaged in the brake-by-wire field for many years. Keeping pace with intelligent driving trends, the company has successfully developed the valve body for the ONE-BOX intelligent integrated braking system, ranking among the top in domestic market share, and has successively achieved breakthroughs in multiple bottleneck technologies, including the hydraulic control unit for electronic stability systems.

Looking ahead, as the brake-by-wire market experiences explosive growth, Real Longding is accelerating the release of newly built production capacity and advancing the expansion of its overseas markets through technical centers in its European headquarters and North America region. The company always upholds the mission of empowering China's intelligent manufacturing with specialization, refinement, and intelligence, and is committed to promoting the domestic substitution of core automotive components, contributing solid strength to the high-quality development of the global automotive industry.
