On July 30, 2025, Jiangxi Xinkuang Zhiwei Engineering Technology Co., Ltd. (hereinafter referred to as "Xinkuang Zhiwei"), a wholly-owned subsidiary of Nanchang Mining Machinery Group Co., Ltd, successfully signed a "Product Crushing Production Line Operation and Maintenance Contract" with a mining company in Hunan. According to the contract terms, Xinkuang Zhiwei will carry equipment to provide comprehensive operation and maintenance services for a newly built molybdenum ore crushing production line for the customer for a period of ten years. The total contract amount is expected to reach RMB 96 million.

This signing is an important achievement of NMS's strategic transformation from a traditional equipment manufacturer to a comprehensive solution provider of "equipment manufacturing+services". Xinkuang Zhiwei, as a key carrier for the deep cultivation of aftermarket services by NMS, has been dedicated to providing full lifecycle services for mining customers since its establishment in 2021, including spare parts, complete machine maintenance and repair, and production line operation and maintenance. It is committed to helping customers improve production efficiency, reduce operating costs and failure rates, and achieve dual improvement of production capacity and efficiency.

Xinkuang Zhiwei has always adhered to customer demand orientation, built a global service network, and implemented a 7 × 24-hour rapid response mechanism to provide personalized spare parts solutions and precise maintenance services. It has created a comprehensive service system from product delivery to full lifecycle management, and its technical strength has been verified in multiple projects. At a large iron mine in Sichuan, the lining plate provided by Xinkuang Zhiwei was successfully applied to a well-known imported brand of gyratory crusher, which operated continuously and stably for 11 months with excellent performance and a lifespan far exceeding expectations. At the same time, Xinkuang Zhiwei also assisted customers in upgrading and transforming their equipment protection and control systems, winning their trust in domestic spare parts with efficient and professional services.

In the field of equipment maintenance and process optimization, Xinkuang Zhiwei has demonstrated outstanding capabilities. Taking a polymetallic mine project in Chenzhou, Hunan Province as an example, Xinkuang Zhiwei has formed a team of senior experts to conduct a comprehensive diagnosis on-site and tailored a maintenance plan that integrates safety, efficiency, and environmental protection. By analyzing the stone samples, redesigning the process flow, optimizing the equipment cavity and wear-resistant parts materials, the service life of key components and equipment output per unit time have been significantly extended; By adding environmental protection equipment and improving the electrical system, intelligent functions such as one click start stop, remote monitoring, load optimization, fault warning, and automatic diagnosis have been achieved, effectively reducing labor costs. The project ultimately stabilized the production line's output at 350-400 tons, with a single line running for 12 hours a day to meet the needs of the selection plant, significantly reducing operating and maintenance costs; The equipment failure rate has been reduced to within 3%, effectively eliminating unexpected shutdowns; The average service life of wear-resistant parts has increased by more than 50%.

In addition, Xinkuang Zhiwei is also unique in the field of remanufacturing mining machinery. Relying on a nationwide after-sales service network, the company has gathered top technical talents from home and abroad, following strict scientific processes (inspection, cleaning, disassembly, testing, scheme design, remanufacturing and processing, final inspection) to ensure that the performance of remanufactured equipment meets or exceeds the level of new products. At present, Xinkuang Zhiwei has successfully completed multiple imported equipment remanufacturing projects, and its significant effects have been highly praised by users and widely recognized by the market.
