At present, the remanufacturing of automobile parts and components in Europe and the United States and other countries has basically reached more than 80%, and a complete system has been formed in terms of technology, processing, and sales, while the domestic products are mainly concentrated in the added value of engines, transmissions, and motors. With regard to high-quality auto parts, there is no concern for other parts and components in terms of technology, capital, and equipment. Simply put, remanufacturing technology is a manufacturing technology that uses high-tech reprocessing of used equipment and parts as blanks to make remanufactured products meet or exceed new product quality. The remanufacturing industry is an environment-friendly industry that reuses resources. What are the reasons that have constrained the development of China's remanufacturing industry? How will China's remanufacturing road move forward? This reporter conducted a follow-up investigation. Misconception: Remanufacturing is a renovation On June 15th, Dong Hua Cummings Liu Hua gave him eight years of freight. He created another "heart". This made him worry that his colleagues in the old market of milk wards in Chaoyang District of Beijing worry: This transformation has The engine looks like a new guy, but practical is not practical? Liu Hua told them that manufacturers in Shandong say that quality assurance is the same as new ones. In talking, Liu Hua also presented a quality warranty testimony. Liu Hua likes to try new things. All mobile phones use the Internet, and he is now ready to buy 3G mobile phones. Cummins, who helped him make money, is old, but he is reluctant to lose it, and then the manufacturing technology just helps him. Isn't it refurbishing? What new term is called for remanufacturing? Liu Hua’s fellow peasant worker Lao Li from Sichuan often laughed at Liu Hua’s “new wordsâ€. Whenever this time comes, only Liu Hua of junior high school does not know how to answer. Compared to the European and American remanufacturing industry, which has a history of more than 50 years, China's remanufacturing industry is still a new industry. The reporter learned from the interview that there are only a few formal automobile remanufacturing companies in the country. In addition to the tire industry, there are more than 100 large-scale tire remanufacturing companies, and the total number of other auto parts remanufacturers is no more than 10. Due to sources of raw materials and restrictions imposed by national laws and regulations, these companies generally have small production capacity and products are mainly Sell ​​to overseas markets. Many people do not know the true meaning of remanufacturing, and even some senior intellectuals are not clear. Under such circumstances, it is not surprising that people simply understand remanufacturing technology as refurbishment technology. “Refurbishment is a common and inaccurate term used by ordinary people. The current product refurbishment is mainly used for scrap tires. This erroneous concept is one of the reasons for the impediments to the advancement of the remanufacturing industry.†Deputy Director, National Defense Key Laboratory of National Equipment Remanufacturing Technology Zhang Wei introduced that remanufacturing is an industrialization of high-tech repair and transformation, which belongs to advanced manufacturing and green manufacturing. From the application scope to the analysis of the contribution to the recycling economy, remanufacturing is superior to renovation. The key factor that caused the misunderstanding of consumption may be due to insufficient publicity and due to the lack of related technical standards that are currently in place. However, Zhang Wei also emphasized: "In an enterprise, remanufacturing is entirely controlled in accordance with the process standards and product quality standards for new machine manufacturing. If these standards cannot be met, they cannot be called remanufacturing, but only maintenance or overhaul." Technical Difficulties: Life Assessment and Repair “In June this year, we achieved a reasonable layout of the three production lines; in July, we started the TPM (Comprehensive Productive Maintenance) management system for equipment maintenance; in August, the production efficiency was increased by 10% on the existing basis, and the in-product production cycle was shortened by 10%. "The lean production schedule is from China National Heavy Duty Truck Group Jinan Fuqiang Power Co., Ltd. (hereinafter referred to as "Fuqiang"). Prior to this timetable, the Lean Production Office had already placed a license within the company. The reason why it is necessary to promote lean production energetically within the company is mainly due to the re-manufactured activities of the company. As one of the 14 pilot auto parts remanufacturing enterprises launched by the state in March this year, Fuqiang Company hopes to add more “safety belts†to ensure that the remanufactured products are equivalent to new products. Zhang Wei introduced that the remanufacturing work flow mainly includes: dismantling, cleaning, testing, remanufacturing the recovery of the dimensional performance, remanufacturing processing, assembly, bench inspection, and spray paint packaging. Each step in the process is of quality for remanufactured products. influential. Among them, the key processes and technical links for safeguarding the quality level of remanufactured products are: Remanufacturing product dimensional performance recovery and processing and processing procedures, which also imposes higher requirements on processing precision of processing equipment. “Because the remanufacturing process is complicated, the technical level is high, and there are more effective management methods, there will be fewer flaws.†A person in charge of Jinan Fuqiang emphasized the introduction of their original intention of lean production. Although Fuqiang Company has previously passed some certifications in the management system, it has introduced a full range of remanufacturing equipment for Europe and the United States and established a set of technology, production, supply and marketing systems in strict accordance with European and American models and standards. However, it is not an easy task to carry out technological transformation of old auto parts and make it look new. It is not an easy task. What are the technical difficulties? For this, Zhang Wei introduced, The manufacturing process is the hardest to control two quality points: The first is that the technology and methods for assessing the damage and remaining life of used parts and components are still an international problem. It is still not a convenient and quick method to obtain the assessment results of used parts and components. The second is the surface repair technology of damaged parts. The damage patterns of different parts are complex and varied, and the materials and shapes are mostly different. It is necessary to use different repair technologies for different damage forms, different materials, and different shapes. Enterprise å°´å°¬: Faced with "No Rice" According to the statistics of China Association of Automobile Manufacturers, each year, 2 million vehicles are scrapped by automobiles in China. On the one hand, it is a huge market for remanufactured raw materials. On the one hand, companies are facing the embarrassing situation of “no riceâ€. For example, Fuqiang is the only member of the North American Engine Remanufacturing Association (PERA) in Asia, and is also the scientific research and teaching practice base of the National Remanufacturing Technology R&D Base—the National Key Laboratory of Defence Manufacturing Technology for National Defense Science. After expanding in size in 2005, It can produce more than 10 series of more than 20 remanufactured engine products, with an annual output of 50,000 sets of engine parts production lines. However, at present, there is also a situation of “floodingâ€. The “no rice squats†of an enterprise is related to the consumer's concept of consumption, but the most lacking is the laws and policies that promote the development of the remanufacturing industry. Zhang Wei, for example, stated that the huge market of 2 million vehicles still causes the automobile parts to fail due to the lack of regulations and policies concerning the restrictions of the "Administrative Measures on the Retirement of Used Vehicles" and the current methods of recycling, market access, and supervision of remanufactured products. Manufacturing companies face the embarrassment of "flooding." As a company specializing in the remanufacturing of auto parts, the financial crisis since 2008 seems to be an opportunity for Fuqiang: the shrinking of the western automobile market and the improvement of the status of the domestic circular economy, with the cost equivalent to engine overhaul. The re-invention of auto engines into products of equal quality and new products is a golden opportunity for remanufacturing to take full effect. Take this opportunity to re-manufacture products that may actually be “into the halls†in advance and fly into ordinary people. Therefore, the new opportunities allow Fuqiang's top management to make several "stronger" measures in the near future, including the introduction of lean production quality management methods. Policy promotion: Strive to break the monopoly In April 2006, the National Development and Reform Commission's "Report on the Development of Auto Parts Remanufacturing Industry and Suggestions on Related Countermeasures and Measures" set the tone for the development of the remanufacturing industry: promoting pilots, exploring experiences, researching and developing technologies, and revising relevant laws and regulations. The prelude to the automotive parts remanufacturing industry opened. Since 2007, the Armored Forces Engineering Institute and Fuqiang Company have carried out research on key technologies and applications for remanufacturing of auto parts, aiming at the remanufacturing of auto parts and components, focusing on the research and development of key advanced remanufacturing technologies with independent intellectual property rights in China. Strive to break through foreign technical barriers, and strive to break the monopoly of foreign remanufacturing technology and equipment to reach the international leading or advanced level. In October 2008, the National Development and Reform Commission issued the "Notice on Calling for Auto Parts Remanufactured Product Markings." In March 2009, 233 auto parts remanufactured logos collected in the country were selected to publicize the award. In March 2009, the state launched 14 pilot enterprises for the remanufacturing of auto parts and tried to use the government to promote the development of the industry. In May 2009, a remanufacturing research team was formed by the relevant national ministries and industry associations to conduct surveys on the pilot remanufacturing of auto parts. Saving resources, improving utilization, preventing waste generation, and using these benefits of remanufactured products have already constituted a benign ecological chain of resource cycles. With the help of the government's "reduction, reuse, and recycling" principle, it's not easy to say that you don't love you. [next] Link China remanufacturing events In June 1999, Academician Xu Binshi published an academic paper on "Surface Engineering and Remanufacturing Technology" at the International Conference on Advanced Manufacturing Technology. He first proposed the concept of "remanufacturing" in China. In December 2000, the report of the Consultation Project of the Chinese Academy of Engineering, which was completed by 12 academicians and 12 experts, “The prospect of the application of the green remanufacturing project in China†attracted the attention of the leaders of the State Council. In June 2003, China's first national key laboratory in the field of remanufacturing, the National Defense Key Laboratory of Remanufacturing Technology, was established at the Armored Forces Engineering College. In August 2003, the third theme of China's medium and long-term science and technology development plan for 2020 was "Research on the Development of Science and Technology in Manufacturing Industry", which listed "self-repairing and remanufacturing of mechanical equipment" as one of the 19 key technologies that were remanufactured by equipment. The National Defense Science and Technology Key Laboratory is responsible for the demonstration. In November 2004, Xu Kuangdi, President of the Chinese Academy of Engineering, creatively pointed out at the World Engineers Conference that “the foundation of engineering science must shift from the purely scale and efficiency model in the 20th century to the construction of a 4R circular economy†and proposed 4R from the perspective of circular economy. Reduce, Reuse, Recycle, and Remanufacture development strategies. In March 2008, the National Development and Reform Commission held a pilot conference for the pilot remanufacturing of auto parts industry. It approved 14 pilot companies from more than 40 declared companies in various provinces and cities across the country. In October 2008, the National Green Manufacturing Technology Standardization Technical Committee was established. Since 2009, relevant departments are actively preparing for the National Remanufacturing Subcommittee on Green Manufacturing Standardization Technical Committee. Remanufacturing in the United States In the 1930s, the United States suffered the Great Depression. Due to lack of funds and resources, more cars were remanufactured. In 1942, when the United States entered the Second World War, the production of commercial vehicles was under control and remanufacturing became the only way to maintain the operation of cars and trucks. In 1996, the remanufacturing survey report “Remanufacturing: Potential Giants†released by the United States showed that there are 73,000 professional remanufacturing companies in the United States with annual sales of US$53 billion and direct employees of 480,000. At present, remanufacturing projects have penetrated into various fields in the United States, including automobiles, refrigerator compressors, electronic instruments, machinery manufacturing, office equipment, tires, ink cartridges, and industrial valves. In 2005, the proportion of major remanufactured products in the United States was: 56% for automobiles and their accessories, 16% for industrial equipment, 11% for aerospace and defense equipment, 6% for electronic products, and 4% for computer products. Remanufacturing employs 1 million people, annual sales of 100 billion US dollars, and 75% of remanufacturing companies have passed ISO quality system certification. According to the analysis report of the American Iron and Steel Association, the United States has achieved remarkable results in remanufacturing scrapped steel products: 47% to 74% energy saving, 86% reduction in air pollution, 76% reduction in water pollution, 97% reduction in solid waste, and water conservation 40%.
