SIA(SH:600009) Zhong Guo Min Hang Wang·2025-07-20 08:48Core Viewpoint - Shanghai Airport has developed a key technology for rapid screening of weak magnetic materials in large cargo warehouses, significantly improving the efficiency of air cargo logistics and addressing safety concerns in aviation [1][2]. Group 1: Technology Development - The technology, based on "quantum tunneling effect magnetic resistance array sensor technology," allows for simultaneous screening of multiple weak magnetic items within a cargo container, reducing the testing time to under 20 seconds [2]. - This innovation fills a gap in the industry regarding the magnetic testing standards for whole pallets and boxes of cargo, which previously required individual checks that could take 2-3 days [1][2]. Group 2: Economic Impact - The implementation of this technology is expected to save approximately 100 million yuan in logistics costs annually for upstream and downstream customers [2]. - The enhanced efficiency in handling weak magnetic cross-border e-commerce goods strengthens Shanghai Airport's influence in setting international air cargo detection standards and improves the business environment at the airport [2].
