Quality Wins Trust: A Chronicle of Ten Years of Cooperation between Yuezhong Machinery and Lingong

From the initial alignment of ideas to a decade of working side by side, Yuezhong Machinery, with its 17 years of dedication to the field of wear-resistant plates for loader and excavator bucket teeth, has jointly written an industry legend with Shandong Lingong: "Establishing cooperation with quality and building longevity with integrity." Recently, the two parties officially signed a new round of strategic cooperation agreement at Shandong Lingong's headquarters intelligent manufacturing industrial park, marking a new height in this partnership spanning over a decade, in terms of intelligent manufacturing and global expansion.

Looking back at the beginning of the cooperation, Shandong Lingong, as a leading enterprise in China's construction machinery industry, has almost stringent standards for the wear resistance, fitting precision, and stability of core components. At that time, Yuezhong Machinery, which had accumulated nearly seven years of experience in wear-resistant plate manufacturing, stood out among numerous suppliers thanks to its independently developed "high-chromium alloy composite casting process" and "full-process precision quality control system." Its bucket tooth wear-resistant plates, tested by a third party, showed a service life 35% longer than the industry average and were perfectly compatible with the operating conditions of Shandong Lingong's star models, the L955F loader and E6215F excavator. It passed Shandong Lingong's "QCD (Quality, Cost, Delivery)" triple audit, becoming its core supplier of bucket tooth wear-resistant plates.

Throughout the ten-year cooperation, Yuezhong Machinery has always been customer-demand oriented, maintaining a deep partnership with Shandong Lingong's R&D team. In 2020, when Shandong Lingong launched the L968H loader designed for heavy-duty mining scenarios, Yuezhong Machinery immediately assembled a dedicated R&D team. They spent 45 days optimizing the alloy formula of the wear-resistant plates and the tooth structure design, ultimately achieving a 28% increase in impact resistance, successfully meeting the high-intensity operational requirements of the new machine. During the global supply chain fluctuations of 2022, Yuezhong Machinery ensured the stability of parts supply to Shandong Lingong's six domestic production bases and three overseas assembly plants by expanding two intelligent production workshops and establishing a 5,000-ton strategic raw material reserve. On-time delivery rate has remained above 99.8% for ten consecutive years, demonstrating the true meaning of "partner" through its actions.

At the signing ceremony, Wang Jianjun, General Manager of Yuezhong Machinery, stated, “Seventeen years of industry experience have taught us that ‘quality’ is the lifeline of an enterprise; and ten years of cooperation with Shandong Lingong has made us understand that ‘win-win’ is the cornerstone of long-term development. In the future, we will continue to invest 20 million yuan in the iterative R&D of wear-resistant materials, upgrading from ‘precise matching’ to ‘collaborative innovation,’ injecting more ‘Yuezhong strength’ into Shandong Lingong’s global competitiveness.”

Zhang Shiyong, Purchasing Director of Shandong Lingong, also highly praised the cooperation between the two parties: “Over the past ten years, Yuezhong Machinery has not only been our parts supplier but also our ‘partner’ in technological innovation and market expansion. Their commitment to quality and pursuit of efficiency perfectly aligns with our brand philosophy of ‘reliability carries heavy responsibilities.’ We look forward to exploring more possibilities in areas such as green casting and digital supply chain collaboration in this new round of cooperation, jointly contributing to the high-quality development of the construction machinery industry.”

From single parts supply to full-chain collaborative innovation, from regional cooperation to global supply chain co-construction, the ten-year agreement between Yuezhong Machinery and Shandong Lingong is not only an affirmation of past cooperation but also an expectation for future development. In the wave of transformation towards intelligence and green development in the construction machinery industry, this partnership based on quality and trust will surely shine even brighter.
