Sinopec Shanghai Engineering, in collaboration with the Chongqing Institute of the Chinese Academy of Sciences and JinShenDe Company, successfully passed the project acceptance review for the KSD-400D dual-wavelength metal additive manufacturing system on June 30. The system utilizes a metal powder bed with dual-wavelength laser technology, making it compatible with petrochemical-specific materials such as nickel-based and high-temperature alloys, and meeting the additive manufacturing needs of high-temperature, difficult-to-weld alloys. The team resolved technical challenges including insufficient elongation of printed parts and poor plasticity and toughness after heat treatment. This achievement marks a milestone in Sinopec Shanghai Engineering’s innovation-driven development and supply chain security efforts, addressing a critical gap in domestic additive manufacturing for high-end petrochemical equipment. The company will continue to focus on original and leading core technologies to build a self-contained, modern energy and chemical equipment system.
