The process of remanufacturing can be broken down into five primary stages: the dismantling of engineering machinery, the cleaning of its components, the testing and life assessment of these parts, their repair and remanufacturing, and finally, the assembly of the reassembled machinery. Notably, a well-established remanufacturing process employs advanced scientific methods throughout each phase to ensure the quality and performance of the finished product. To illustrate, let’s focus on two critical steps within this process. During the inspection and life assessment of engineering machinery parts, remanufacturing companies often utilize metal magnetic memory technology for evaluating the remaining lifespan of used components. This technology relies on the magnetostrictive properties of ferromagnetic materials, which possess a magnetic domain structure and spontaneous magnetization under geomagnetic conditions. When subjected to external forces, changes occur within the magnetic domains, and these alterations leave traces in the magnetic field that persist even after the force is removed. By analyzing these "magnetic memories," engineers can detect stress concentrations and micro-cracks, enabling early damage detection and accurate life assessments.
In the subsequent step—repair and remanufacturing—the focus shifts toward restoring and upgrading used parts to meet performance standards. Here, surface engineering techniques, including nano-surface and automated surface engineering, play a pivotal role. These methods not only enhance durability but also optimize functionality.
China's remanufacturing sector aligns closely with the nation's 12th Five-Year Development Plan. Since the late 1990s, the concept of "remanufacturing" began gaining traction in China, and the government has consistently shown interest in fostering this industry. Key milestones include the issuance of directives in 2005 encouraging the reuse of mechanical and electrical products and the explicit mention of remanufacturing in the "Eleventh Five-Year Plan." More recently, the "12th Five-Year Plan for Energy Conservation and Environmental Protection Industry Development" outlined specific initiatives, including projects focused on advancing remanufacturing industries, particularly in automotive parts, engineering machinery, and machine tools. The plan also emphasizes enhancing recycling systems and establishing national remanufacturing clusters.
From an economic perspective, China's rapid industrialization and rising living standards have spurred significant growth in the production of mechanical and electrical goods, creating ample opportunities for remanufacturing. According to data from the China Construction Machinery Industry Association, there are currently over 5 million units in the domestic construction machinery market, with annual sales projected to reach 1 million units by 2015. By 2020, it is estimated that around 1.2 million units will be scrapped annually. Additionally, individual parts like those found in engineering machinery hold high repair value due to their significant unit prices, further fueling demand for remanufacturing services.
With increasing domestic market penetration of construction machinery, coupled with supportive government policies and enhanced international collaboration, China stands poised to emerge as one of the leading global hubs for remanufacturing. As the world's largest holder of construction machinery, China holds immense potential within this burgeoning field.
