Recently, as a supplier, Yanming Chemical was invited to send Han Tao, Deputy General Manager, and Engineer Liu, Quality Engineer, to attend the "New Material Industry Group Suppliers' 'Zero' Foreign Matter Special Improvement Conference" hosted by Huayou Cobalt. This conference systematically shared the closed-loop management system covering six dimensions—personnel, equipment, materials, methods, environment, and measurement—from the "Suppliers' 'Zero' Foreign Matter Improvement Initiative", which greatly inspired the participants and enabled them to gain substantial insights. The company attaches great importance to the outcomes of the conference and promptly organized a special learning session for management personnel and key position holders to promote the in-depth integration of the conference experience with its own production practices, and effectively implement the "zero" foreign matter management requirements.

Conference Insights: Full-Process Control, "Zero" Foreign Matter is the Quality Lifeline of Suppliers

"The refined approach of Huayou Cobalt in 'zero' foreign matter management has made us deeply realize that as a supplier, the control of every production link is directly related to product quality and cooperative trust," Han Tao, Deputy General Manager, emphasized when sharing his conference experience at the learning session. He noted that the measures mentioned in the conference, such as "pocketless work clothes" and "adhesive roller testing" for personnel management, "color-coded tools" and "full-life-cycle traceability of spare parts" for equipment management, as well as "prohibition of galvanized parts" and "rapid XRF screening of incoming materials" for material management, have integrated the "zero" foreign matter concept into every detail from the source to the end, completely changing the previous understanding of foreign matter control.

He specifically mentioned that the "foreign matter metal map" constructed in the "Suppliers' 'Zero' Foreign Matter Improvement Initiative" uses a dynamic visual database to predict risks in advance, transforming passive response into active prevention and control. This data-driven management thinking provides suppliers with a clear direction for optimization. "Chemical products have extremely high requirements for purity, and any tiny foreign matter may cause serious quality problems. The practice of Huayou Cobalt fully proves that only by permeating the 'zero' foreign matter requirement throughout the entire process can we truly meet customer needs, stabilize the supplier's position, and enhance the enterprise's brand influence."

Precise Implementation: Focusing on Construction Practice, Raising Technical Standards, and Solving Foreign Matter Control Problems Through Details

Combining the characteristics of the production links of Yanming Equipment as a supplier, Engineer Liu, Quality Engineer, benchmarked against the management standards in the "Suppliers' 'Zero' Foreign Matter Improvement Initiative", broke down the details of the customer's (Huayou Cobalt) process flow, matched the characteristics of its own drying equipment, and conducted a detailed analysis on improving process standards.

Taking the connection process as an example, Engineer Liu pointed out that it is necessary to strictly follow the "zero tolerance" requirement for "foreign matter management of incoming hardware components" in the initiative and significantly improve welding precision: "For some small joints and irregular parts that are difficult to polish, 'no burrs' must be taken as the core standard in the future. After welding, the weld joints need to be carefully and repeatedly polished to ensure that there is no protrusion when touched by hand, completely eliminating the risk of metal debris falling off. At the same time, referring to the 'post-maintenance cleaning confirmation' process in the initiative, various debris generated after welding and polishing must be handled, such as wiping or vacuuming."

Engineer Liu also admitted that some operational improvements still require technical breakthroughs. For example, the cleaning verification after fine polishing and the process adjustment involved in "bolt-free" operations need to be repeatedly tested in collaboration with the production team and the company's suppliers to ensure that foreign matter risks are avoided while meeting the firmness requirement. This will be a key direction for the company's continuous optimization as a supplier.

Summary and Deployment: Emancipating the Mind to Implement, Consolidating the Foundation of Cooperation with "Zero" Foreign Matter

"The 'Suppliers' 'Zero' Foreign Matter Improvement Initiative' of Huayou Cobalt has pointed out the direction for us. As a supplier, only by effectively implementing 'zero' foreign matter management can we gain a firm foothold in cooperation. Although the amount of foreign matter in our company's equipment is already the lowest in the industry, we need to make it even lower in the future," Xu Yanguo, General Manager of the company, emphasized in his summary speech. He stated that all staff must emancipate their minds, change their concepts, break the inherent perception that "foreign matter control relies only on the quality department", and establish the concept of "full-staff participation and full-process control". He required all departments to take this learning session as a starting point, formulate clear promotion plans, and regularly review the improvement effects against the requirements of the initiative. General Manager Xu said, "As long as we move forward steadily and refine every technical detail, we can continuously improve the 'zero' foreign matter management level, consolidate cooperation with customers with better-quality products, and achieve long-term development. This is not only responsible for customers but also for our own brand."
