Operational & Technical Details

The Nanjing facility is Siemens’ first built entirely from a digital blueprint. Every process was simulated and optimized using a comprehensive digital twin before physical assembly. This approach allowed for faster construction and integration of complex systems. The plant utilizes Siemens’ Digital Twin Composer software, which leverages Nvidia Omniverse libraries to create photorealistic, real-time virtual models of the entire operation.

This virtual environment enables rapid iteration and problem-solving without physical disruption. To manage increasing order variability and shrinking delivery times, the factory deployed more than 50 distinct AI applications. These systems, combined with modular automation, provide the flexibility needed for high-variety, low-volume production of controls for machine tools, drives, and electric motors.

Market Impact Analysis

By achieving Lighthouse status, Siemens validates its “Digital Native Factory” concept as a new industry benchmark. The Nanjing plant now functions as a powerful showcase for Siemens’ Digital Industries software and automation hardware, demonstrating tangible ROI for digitalization to potential customers. The success of this model strengthens Siemens’ competitive position in the advanced manufacturing sector in China and globally. Furthermore, the documented 28% reduction in carbon emissions provides a clear blueprint for other industrial players to link productivity gains directly with sustainability targets, meeting rising ESG demands from investors and regulators.
