4.4 Quality, Monitoring & Data Infrastructure

The Manufacturing Quality Inspection & Control System is a systematic, factory-wide approach designed to ensure that every raw material, in-process component, and finished battery cell consistently meets predefined specifications. This is not a single machine but an integrated system of measurement, analysis, and action. It encompasses three key stages: Incoming Quality Control (IQC) for raw materials, In-Process Quality Control (IPQC) to monitor the manufacturing steps in real-time, and Final Quality Control (FQC) to validate the finished product. By leveraging a network of sensors, metrology equipment, and sophisticated software like the Manufacturing Execution System (MES), this system aims to move from a traditional "inspect and reject" model to a proactive "predict and prevent" model, ultimately reducing scrap, improving manufacturing yield, and guaranteeing the safety and performance of the final battery cells.
