Weichai: Remanufacturing and Developing a New World for Industrial Development

Remanufacturing refers to the mass production process of professionally rehabilitating used auto parts, engineering machinery, machine tools, etc. The remanufactured products achieve the same quality and performance as the original new products. It is a high-level form of circular economy “reuse”. China will increase the level of remanufacturing technology, expand the field of remanufacturing applications, cultivate remanufacturing model enterprises, standardize the recycling system of old parts, and develop domestic and foreign markets as the main tasks. Remanufacturing can not only reduce resource consumption and environmental pollution from the source, but also It can enhance the competitiveness of traditional industries and provide plenty of employment opportunities.

A green technology

In the eastern part of Weifang City, Shandong Province, Weichai Group has a brand new factory area. In the new factory area, there are both traditional engine manufacturing industries and some engine-related emerging industries. Among them, the engine remanufacturing industry is a dazzling wonderful work in the gardens of China's machinery industry.

Entering the spacious and bright workshop of Weichai Remanufacturing Co., Ltd. makes people feel a lot of vision. As soon as I asked, the workshop had a total area of ​​approximately 27,000 square meters.

On the face is a red slogan: "A little bit of progress every day, do you improve today?" Remanufacturing company general manager Li Feng, chatting with reporters under the banner. In March 2008, China's auto parts remanufacturing pilot work was officially launched. Weichai has become one of 14 pilot companies.

Li Feng said that remanufacturing is the use of new technologies to repair and reprocess worn-out engines. As old as new, its power, economy, and warranty period are exactly the same as those of new machines. This is a low-cost manufacturing model, a high-level form of circular economy, and a new thing in China's machinery industry. According to statistics, for every 10,000 remanufactured engines produced, the added value of recycling is close to 360 million yuan, which can save 14.5 million kWh and reduce carbon dioxide emissions by 600 tons. Compared with remanufactured new products, remanufacturing can save energy by 60%, reduce atmospheric pollutant emissions by 80%, and bring about significant economic and social and ecological benefits.

New company, new industry. New equipment, employees are young. Li Yungang, 24 years old, graduated from college and entered WeiChai in 2010. Talking about remanufacturing, it is said that the remanufacturing of engines is to make good use of the spare parts of used machines, rework or replace failed parts, and finally reassemble them. The scrapped engine passed this remanufacturing line and regained its vitality. Accelerating the development of the remanufacturing industry will promote the formation of a circular economy model of "resources-products-waste products-remanufacturing products", make full use of resources, protect the ecological environment, and promote the construction of a resource-saving and environment-friendly society.

Li Yongtao, 28 years old this year, was transferred from Weichai 615 Factory and is currently the head of the remanufacturing company's pre-installation test. He told reporters that he did not understand the new industry of the remanufacturing industry and only discovered that it was a rapidly growing industry. In the past few years, remanufacturing has been working hard on the ability and the level. From the beginning of the month, it produced dozens of units, and now it has produced over a thousand units a month, but it still can't meet the market demand.

Ding Wei, deputy manager of the Technical Quality Department, told the reporter: “Our company is a wholly-owned subsidiary of Weichai Group, and we have technically cooperated with SRC Corporation of the United States and our equipment has reached the international advanced level. Weichai 36 service centers and all over the country Thousands of repair stations have provided convenience for the recycling of used engines. Our remanufacturing has achieved mutual benefits and win-win results in many aspects of the industrial chain: For users, purchasing remanufactured products is equivalent to the new machine at a lower price. The performance and service of the old user's old and waste products also added value; for the repair station, the business of recycling of used machines was increased, which is a new selling point and profit growth point; for the OEM, the industry was lengthened. The chain enhances the contact with users and improves economic efficiency.” At the same time, some technologies and processes for reprocessing damaged parts on the surface of remanufactured parts can be applied to the production of new engines to further improve their performance and quality.

A lean team

Sun Zhanchang is 48 years old this year and is the demolition plant section of the remanufacturing company. He told reporters that since he began to work in 1979, he has experienced the difficulties of Wuichai's continuous loss year after year, and has witnessed rapid growth in the past decade or so. In this new position, Master Sun is very proud: “We are a special team of Weichai. An engine that has lost its use value, covered with oil, worn out, passed our hands and gave it new life. It's a new look and it's no different from a new machine. It's amazing."

Master Sun told reporters: “In order to bring in the 'new recruits' of this special team, I have given this 30-year experience to us.” Master Sun’s more than 30 apprentices have already taken great steps in various processes.

Under the leadership of Li Feng, the reporter walked along the production line while watching and talking. He did not miss every step and witnessed the entire process of engine remanufacturing. The old machine is recycled into the factory, first dismantled into a single part, and then all the parts are disassembled, measured, cleaned, tested, the failed part is reprocessed or replaced, and finally reassembled, so that the already scrapped engine is fully restored to the new product. Quality status. At the end of the test, the new engine that had just been remanufactured was running cheerfully. Various technical indicators and performance are displayed on the computer.

Through interviews with employees and research company materials, reporters have a deeper understanding of remanufacturing. As a green manufacturing technology, it takes the product life cycle theory as a guide, and uses advanced technology to realize the recovery of used product performance. Nano-surface engineering technology is one of the key supporting technologies for remanufacturing projects. Utilize the special properties of nanomaterials to change and enhance the morphology, composition, and structure of the surface of worn and corroded parts and materials so that their quality and performance can meet or exceed new products.

It is roughly estimated that there are currently about two or three million units of Weichai engines in the market, and they are growing at an annual rate of more than 400,000 units. Faced with the prospects of a vast remanufacturing market, Tan Xuguang, chairman of Weichai Group, said that the development of the remanufacturing industry should be used as a breakthrough point for companies to fulfill their social responsibilities, promote energy conservation and emission reduction, and cultivate new growth points, and promote the development of remanufacturing industries. They intend to further expand the field of remanufacturing, from the expansion of engines for vehicles to engines for engineering, marine and power generation, and to enlarge and strengthen the remanufacturing industry.

The investigations conducted in the past few days have made reporters excited. China has a large number of machinery and equipment put into use every year. At the same time, a large number of used auto parts, engineering machinery, machine tools, and other machinery products with high added value are being used because of wear and corrosion. The practice of Weichai shows that the development of the remanufacturing industry is a new opportunity for China's machinery and other industries, and its prospects are boundless. In 2010, China issued the "Opinions on Promoting the Development of Remanufacturing Industry" to provide policy support for this new industry. We look forward to the fact that with the joint efforts of pioneers such as Weichai, our country’s remanufacturing industry will soon grow from a strain of seedlings and grow into a dense forest of trees.
