Remanufacturing technology is the core step in the production of remanufactured products. It is of great significance to ensure the quality of remanufactured products and reduce production costs. In this paper, the development and application status of remanufacturing technology are summarized. According to the damage forms of parts, remanufacturing technology is divided into surface failure oriented remanufacturing technology and structural damage oriented remanufacturing technology. A variety of typical remanufacturing technologies are classified and listed. Their processing principles are introduced, and the application in remanufacturing parts is illustrated and reviewed. Finally, the existing problems of remanufacturing technology are summarized, and the development trend of remanufacturing technology in the future is prospected.
