The workshop takes "local management, hierarchical responsibility, comprehensive coverage, and personal responsibility" as its principles, and innovatively implements a grid-based quality control system to drive continuous improvement in product quality. The workshop has built a three-level grid-based quality control system, covering all staff from workshop directors to operators, so that there are no blind spots in the quality management of the eight major areas. At the same time, starting from the six major elements of "people, machines, materials, methods, environment, and measurement", four major control modules are established, 569 key risk control points are identified, and emergency response mechanisms are provided. In addition, differentiated inspection plans are formulated based on risk points, and a strict closed-loop management mechanism for problems is implemented to promote continuous improvement in quality management, creating a good atmosphere of "everyone cares about quality and everyone participates in management." ！
