Jiangsu Haifa Machinery Manufacturing Co., Ltd.

Ningbo Shenglong Automotive Powertrain System Co., Ltd. (hereinafter referred to as "Shenglong Shares") announced via its WeChat public account that the high-pressure pump head, a core component independently developed by the company for the 800V fully active hydraulic suspension system, has successfully passed customer validation and officially entered mass production. To ensure a smooth transition from trial production to mass production, Shenglong Shares has set up a fully automated assembly line equipped with comprehensive in-process inspection equipment to guarantee the consistency and reliability of every product off the line. The high-pressure pump head now in mass production is a key precision component of the 800V fully active hydraulic suspension high-pressure pump. This product category previously faced multiple industry technical challenges, including high R&D and design thresholds, stringent machining precision requirements, and difficulties in high-pressure sealing. Leveraging its national-level enterprise technology center, Shenglong Shares' R&D team has overcome these challenges through multiple rounds of technical breakthroughs, successfully resolving issues such as high-pressure dynamic sealing, precision fit, and wear resistance, achieving full domestic production and independent control of this core component. Building on Shenglong Shares' years of technical expertise in pump products, combined with mature one-dimensional simulation analysis, rigorous EOL (End-of-Line) testing systems, and professional NVH (Noise, Vibration, and Harshness) optimization technologies, the mass-produced high-pressure pump head has achieved significant upgrades in operational noise, power consumption performance, and core functionality. Shenglong stated that the company consistently keeps pace with the transformation of the automotive industry, continuously pushing its own boundaries, and remains committed to the philosophy of "providing customers with high-quality solutions." It will continue to strengthen breakthroughs in globally leading technologies such as the high-pressure pump head for fully active hydraulic suspension systems, helping China's automotive industry achieve technological catch-up with overseas luxury brands in the field of chassis dynamic control.
