　　used excavator for saleA mechanical and electrical equipment on the brink of scrapping can be revitalized and put back into use more efficiently after undergoing a series of processes such as disassembly, cleaning, testing, additive manufacturing, mechanical processing, assembly, and testing. The technology of rescuing mechanical and electrical equipment from the scrap edge to the production line is called remanufacturing technology.

　　According to the "Standard Conditions for the Remanufacturing Industry of Mechanical and Electrical Products" recently released by the Ministry of Industry and Information Technology, remanufacturing refers to used excavator for salethe production process of using advanced and applicable processes, technologies, equipment, and materials to professionally repair or upgrade old parts, so that the performance and quality of remanufactured products can reach or exceed those of prototype new used excavator for saleproducts. Remanufactured products must comply with mandatory national standards for safety, energy conservation, and environmental protection.

　　So, has remanufacturing become a new track for the manufacturing industry, what challenges does it face, and what are its future development trends? The reporter interviewed industry experts and practitioners on this matter.

　　It's not just a simple repair

　　Remanufacturing is not just about repairing and refurbishing. The remanufacturing industry in our country has stricter requirements for the performance and quality of products, which must meet or exceed the prototype new products, "said Wu Gang, Director of the Green Development Department of the Environmental Protection Industry Development Center of the Machinery Industry. The strict control of the quality standards of remanufactured products by the country is to eliminate the doubts of the industry and users about remanufactured products, and ensure used excavator for salethat everyone has a clear and unified understanding of remanufactured products.

　　The core technologies of remanufacturing, such as laser cladding technology and surfacing technology, although belonging to surface treatment, their functions are far beyond simple repair. For example, after a long period of operation, the surface wear or loss of blades on the rotating shaft of a steam turbine affects its efficiency. Remanufacturing technology not only enhances the strength, toughness, and corrosion resistance of products by adding metal elements to their surfaces, but also significantly improves their performance.

　　In our country, remanufacturing is not limited to repair, but also includes upgrading and transformation. Wu Gang pointed out that taking shield tunneling machines as an example, a 6-meter diameter shield tunneling machine retired from a certain project may need to be expanded to 8-9 meters according to the needs of the next project. At this point, remanufacturing technology can fully leverage its advantages and upgrade the existing shield machine through diameter expansion.

　　At present, used excavator for saleChina's remanufacturing industry covers fields such as engineering machinery, machine tools, automobiles, heavy machinery, petrochemical general machinery, internal combustion engines, electrical appliances, agricultural machinery, mechanical basic components, cultural and office equipment, etc. In the remanufacturing industry, there are both enterprises dedicated to the production of valves, automotive parts, and cultural office equipment, as well as institutions focused on the manufacturing of high-end equipment such as gas turbines and aircraft.

　　Hebei Ruizhao Laser Remanufacturing Technology Co., Ltd., as a national pilot unit for remanufacturing, is at the forefront of the remanufacturing industry. Han Hongsheng, the Secretary of the Party Committee and Chairman of the company, stated that compared to manufacturing new products, remanufacturing products can save costs by 50%, energy by 60%, and materials by 70%. The emission of air pollutants during the production process is reduced by more than 80%, and almost no solid waste is generated.

　　Han Hongsheng believes that the greatest significance of developing the remanufacturing industry lies in maximizing resource utilization and reducing waste. The development history of the company also proves the enormous potential of the remanufacturing industry in green development. Over the past 18 years of development, the company has grown from a small workshop style enterprise with only 8 workers to a national level specialized and new "little giant" enterprise with total assets exceeding 300 million yuan. It has saved 420000 tons of metal resources, 580000 tons of standard coal, and reduced carbon dioxide emissions by 700000 tons for the country.

　　Wu Gang believes that although there are many new tracks in the manufacturing industry, the role of remanufacturing as a new track in saving resources and reducing costs cannot be ignored, and it may be a track for maintaining permanent and sustainable development.

　　There is still room for potential explorationused excavator for sale

　　After nearly 30 years of development, China's remanufacturing industry still has enormous growth potential to be tapped.

　　Wu Gang pointed out that the current output value of China's remanufacturing industry is still less than 200 billion yuan, which is significantly different from the huge stock of mechanical and electrical productused excavator for sales in the market and the demand for remanufactured products, and the development is not yet sufficient. In addition, the scale of remanufacturing enterprises is generally small and the number is not large. Taking the remanufacturing of automotive parts as an example, even though this field has developed relatively maturely in China, only 66 enterprises have passed the certification of remanufacturing quality management system.

　　At the production level, talent has become a bottleneck for the development of enterprises.

　　Han Hongsheng introduced that the remanufacturing industry has the characteristics of long investment return cycles, high technological and market risks. Currently, China's remanufacturing enterprises are mainly small and medium-sized enterprises. For these enterprises, attracting skilled talents to drive technological innovation is a major challenge. Although Hebei Ruizhao Laser Remanufacturing Technology Co., Ltd. has continuously introduced talents through methods such as "settling in style" and "co construction style", and has established the Hebei Electromechanical Equipment Remanufacturing Industry Technology Research Institute with multiple universities and research institutions such as Tianjin University and Tianjin University of Technology, there is still a shortage of professional talents. Han Hongsheng called on the government to provide more policy support to small and medium-sized remanufacturing enterprises in terms of reducing the burden of qualification maintenance costs and innovating carbon trading quota mechanisms, so that enterprises can retain more funds to attract talents to overcome technical difficulties.

　　At the consumer level, the lack of public awareness of remanufactured products is an important obstacle facing the development of the industry.

　　Wu Gang emphasized that society lacks a comprehensive understanding of the remanufacturing industry, and the public has doubts about the performance of remanufactured products. For example, in the field of automobile maintenance, even if the performance of remanufactured products has reached or even exceeded the standards of prototype new products and has a price advantage, car owners are often more inclined to choose original new products rather than remanufactured products. Therefore, he believes that increasing public awareness and confidence in remanufactured products is crucial.

　　The market outlook is promising

　　The remanufacturing industry still faces challenges such as the lack of industry standards and insufficient market supervision in its development.

　　used excavator for saleWu Gang pointed out that the current recognition of remanufactured products mainly relies on government administrative means, such as the Ministry of Industry and Information Technology has released a catalog of 10 batches of remanufactured products. However, with the development of the market and the expansion of the industry scale, in the future, the certification of remanufactured products may gradually shift towards market certification mode.

　　In addition, the remanufacturing industry lacks a unified statistical caliber and system, relying only on a few industry organizations to calculate through limited data samples, which makes it difficult for the final data to accurately reflect changes in industry output value, enterprise growth and decline, and other development dynamics. This not only affects the accurate grasp of industry dynamics by relevant departments, but also restricts the precision of policy formulation, which to some extent hinders the rapid development of the industry.

　　From a policy perspective, the government has introduced multiple policies to support the development of the remanufacturing industry. From the "Opinions on Promotingused excavator for sale the Development of Remanufacturing Industry" issued by the National Development and Reform Commission in 2010, which pointed out that remanufacturing is an advanced form of "reuse" in the circular economy, to the "Action Plan for Promoting Large scale Equipment Renewal and Consumer Goods Trade in" issued by the State Council in 2024, which emphasizes deepening the remanufacturing of traditional equipment such as automotive parts, engineering machinery, and machine tools, and exploring the development of high-end equipment remanufacturing business in emerging fields such as wind power, photovoltaics, and aviation. These policies provide strong support for the development of the remanufacturing industry. Han Hongsheng predicts that under the dual drive of national policy support and market demand growth, the remanufacturing industry is expected to enter a stage of rapid development.

　　used excavator for saleWu Gang stated that China is actively expanding its export markets to regions such as Central Asia, Southeast Asia, Africa, and South America. In terms of export strategy, in addition to promoting high-end advanced industrial equipment, economically applicable remanufactured products will also be appropriately promoted. Therefore, he expects the remanufacturing industry to continue to maintain a strong annual growth trend of 15%, used excavator for saledemonstrating broad market prospects and development potential.
