To continuously promote the implementation and deep-rooted adoption of lean management and to help comprehensively enhance the company’s operational efficiency and environmental appearance, the company organized a 5S management on-site observation and exchange event on September 30, 2025, covering Factory No. 1, Factory No. 2, and all functional departments. This event systematically reviewed the practical achievements of each department in areas such as sorting and organizing, and several distinctive improvement cases emerged, earning high recognition from the company’s leadership.

In the office building area of Factory No. 1, various departments have actively promoted 5S management in line with their specific business needs: The Sales Department has optimized its document classification system to accommodate frequent business trips; the General Management Department has introduced comprehensive cleaning standards and a well-organized system for sorting and storing items; and the Finance Department has achieved meticulous filing in the documentation room. These practices fully demonstrate the targeted approaches and seamless integration of functional departments into the 5S implementation process.

The improvements in the production areas have been particularly remarkable. Faced with challenges such as aging equipment and weak foundational infrastructure, the Casting Division of Factory No. 1, under the leadership of Minister Cheng Xinhuan, pooled collective wisdom and achieved significant results in 5S initiatives. Several improvement measures have now been effectively implemented into the production process. Similarly, all areas of Factory No. 2 have demonstrated a high level of refined management: The machining workshop office strictly adheres to the “one desktop, seven items” standard, ensuring efficient and orderly online operations; the accessory storage area is managed according to rigorous and well-defined procedures; the casting workshop’s cultural corridor has seamlessly integrated management practices with cultural elements; and the hazardous waste storage facility has undergone a safety upgrade, while the sand-coating workshop has introduced classified sand management—all of which reflect the continuous deepening of management efforts.

In the summary and review session, company leaders fully affirmed the achievements made in improvement efforts. General Manager Li specifically praised the remarkable progress seen in Production Line 1 of the Machining Workshop at Factory No. 1, the Cultural Corridor in the Foundry Workshop at Factory No. 2, and Production Line 4 of the Machining Workshop at Factory No. 2. He urged all departments to learn from these best practices and continue to consolidate their gains. Meanwhile, General Manager Han emphasized from a conceptual perspective that the essence of improvement lies in enhancing efficiency and shifting mindsets. He expressed appreciation for the improvements made in areas under Minister Wang’s jurisdiction, including Foundry Workshop No. 1 at Factory No. 1 and the Foundry Maintenance Room. He pointed out that measures such as rapid mold changes and optimization of sand core platforms have indeed created tangible value. Furthermore, he encouraged all departments to break down barriers, learn from each other, strengthen full staff participation, and ensure that the culture of continuous improvement truly takes root and flourishes.

This comprehensive inspection demonstrates that 5S management has gradually evolved from its initial stage of sorting and organizing to a new phase characterized by deep integration with business processes and a relentless pursuit of enhanced efficiency. Moving forward, the Lean Promotion Office will guide each department—using leadership feedback as a guiding principle—to continuously expand the scope of improvement, strengthen cross-departmental communication, and conduct regular follow-up reviews. Together, we will create a work environment that is efficient, clean, and standardized, injecting sustained momentum into the company’s high-quality development.
