Siemens Numerical Control (SNC) Nanjing operates in a highly variable manufacturing environment, managing high-mix, low-volume orders with monthly line changes and delivery timelines compressed from 45 days to 10. In response, SNC Nanjing launched a coordinated digital transformation, supported by a comprehensive toolkit spanning end-to-end digital twin technology, modular automation, advanced manufacturing operations and more than 50 AI-driven use cases. The initiative reduced lead time by 78%, accelerated time-to-market by 33%, lowered field failures by 46% and boosted productivity by 14%. It also benefitted SNC's sustainability performance thanks to a 28% reduction in Scope 1 & 2 carbon emissions.
