The High-Performance Precision Forming Team, hailing from the School of Mechanical Engineering at Dalian University of Technology, has triumphantly attained mass production capabilities for monolithic rocket propellant tank bottoms, boasting diameters surpassing 2 meters. This milestone has been achieved through the utilization of the internationally groundbreaking "ultra-low temperature forming technology." The implementation of this technology has led to a remarkable reduction of over 90% in the manufacturing cycle, with an impressive annual production capacity of 1,000 units. This innovation effectively tackles the prevalent global issues of cracking and wrinkling encountered during the forming process of ultra-thin aluminum alloy shells. Moreover, it optimizes material usage, minimizes manufacturing expenses, and is poised to pave the way for high-frequency launches within the commercial space sector, aligning with international standards and practices.
