In today's automotive industry, undergoing a deep transformation towards electrification and intelligence, the thousands of fasteners in each vehicle serve not merely as connecting components but as the very "skeleton" safeguarding lives. The failure of a single 10.9-grade main reduction gear bolt can cripple a high-torque motor, while a minute hydrogen embrittlement crack could have catastrophic consequences on the road. Zhejiang Jieneng Auto Parts Co., Ltd. understands this implicitly. Its three-decade-long dedication to rigorous quality systems and meticulous process control forms the most robust defense line for automotive safety.
Quality is the cornerstone of Zhejiang Jieneng's existence. Beyond obtaining IATF16949 and other international automotive quality management certifications, the company has established comprehensive, end-to-end in-house testing capabilities. Its CNAS-accredited laboratory is equipped with advanced monitoring and inspection tools, including temperature control, metallographic structure analysis, universal testing, torque testing, and salt spray testing. To counter the "hidden killer" of hydrogen embrittlement common in high-strength fasteners, Jieneng employs strict dehydrogenation processes and subsequent inspections to effectively mitigate the risk of delayed fracture. In critical areas like new energy vehicle drive systems, bolts must withstand high-frequency vibration and complex stress environments. Through precise control over friction coefficients and clamping force, Jieneng ensures every bolt achieves the required preload during assembly, preventing loosening failures due to torque decay.
This relentless pursuit of safety and quality has earned the company long-term market trust. As a long-standing supplier to FAW Jiefang and other major domestic OEMs, Jieneng's products have proven their mettle in the demanding conditions of commercial vehicles. This reliability stems not only from the credibility of its CNAS-accredited lab but also from a corporate culture deeply rooted in the principles of "customer first, technology foremost." As China's automotive industry surges forward, Zhejiang Jieneng is using these "safety screws" to fortify the skeleton of domestic vehicles, ensuring the smooth and steady journey of "Made in China."
