Remanufacturing application of automobile parts in assembly

With the acceleration of global industrialization and the improvement of environmental protection awareness, green production and circular economy have become the important direction of manufacturing development. In this context, the remanufacturing technology of automobile industry came into being and gradually became one of the key forces to promote industrial transformation and upgrading. This paper will discuss how to realize resource-saving and environment-friendly production mode through remanufacturing in the assembly process of automobile parts.

First, the concept analysis

1. Remanufacturing refers to the process of repairing and transforming waste products to make them return to the performance level close to the original factory.

2. Remanufacturing of automobile parts refers to the technical activities of recycling core components such as engines, transmissions and air-conditioning compressors.

Second, the significance of implementation

1. Cost saving: Compared with brand-new manufacturing, adopting remanufacturing technology can greatly reduce material consumption and energy consumption; At the same time, it can also reduce the amount of waste and avoid environmental pollution.

2. Promote employment: The remanufacturing industry needs a large number of professional and technical personnel to participate in it, which creates new jobs for the society.

3. Prolonged service life: The remanufactured parts that pass strict inspection can meet the use requirements and prolong the overall service life of the vehicle.

4. Conforming to the policy orientation: A series of policies and measures have been issued at the national level to encourage and support the development of circular economy, such as the Circular Economy Promotion Law of the People's Republic of China and other documents clearly point out that remanufacturing work should be promoted in various fields, including the automobile industry.

Third, key technologies

1. Precision cleaning technology: ensure that all pollutants are removed without damaging the surface quality of parts;

2. Surface engineering treatment methods: such as electroplating and spraying to restore or enhance the original functional characteristics;

3. Application of NC machining equipment: ensure the dimensional accuracy to meet the standard requirements;

4. Advanced testing means: use X-ray flaw detector, ultrasonic testing device and other tools to conduct a comprehensive inspection to eliminate potential safety hazards.

Fourth, case analysis

A well-known automobile brand has set up a subsidiary in China, which specializes in dismantling used cars and refurbishing spare parts. The enterprise has not only established a complete supply chain management system, but also developed a number of core technologies and patent achievements with independent intellectual property rights, which have been widely recognized in domestic and foreign markets. According to statistics, the annual sales of all kinds of reproductions it produces have exceeded 100 million yuan, effectively promoting the double harvest of local economic and social benefits.

To sum up, it is a trend of the times to introduce the concept of remanufacturing in the assembly process of automobile parts, which not only meets the requirements of Scientific Outlook on Development, but also creates more value for enterprises. In the future, we have reason to believe that with the continuous progress and improvement of science and technology, this field will usher in a broader development prospect.
