A mass production assembly line, imported robots from KUKA are used in the plant. Robotic automation in welding reaches 90%. Overhead EMS mechanized transport chains are adopted among the assembly lines. First-stage assemblies like body in white are conducted under flexible production. Multiple models are processed in batch and in turn. Key parts and equipments in main bodywork welding are imported. Quality control uses online robotic detection, lower car body and body in white automatic robotic detections.
