Precision 1/20th of a Human Hair! SAIC Power's "Master Ren" Team Ensures Engine Manufacturing Excellence

At the engine production workshop of Shanghai New Power Automotive Technology Co., Ltd., precision control is pushed to the extreme—tolerances are kept within one-twentieth the width of a human hair. As the manufacturing hub for the automotive "power heart," the facility houses a dedicated Skills Master Studio tasked with tackling production-line challenges, led by Ren Jianxin, affectionately known among colleagues as "Master Ren." He and his team understand that even minuscule deviations at the manufacturing front end can amplify through subsequent processes; therefore, achieving ultimate precision at the source is essential to ensuring consistent, reliable vehicle quality. This relentless pursuit of detail has become a key driver behind China's high-quality development in automotive manufacturing.
