Abstract:Remanufacture engineering plays an important role in the construction of energy-saving society and the achievement of sustainable development. As an important part of the remanufacturing process, cleaning has a direct impact on the performance analysis, surface inspection, machining and assembly of remanufactured products. The main cleaning technologies and methods for remanufacturing procedure were researched on the basis of introducing the main objects of remanufacturing stages, and its future development trend was prospected.
