(Reported by Hou Yongchao from Department of Heavy Forging & Extrusion Technology) On the afternoon of March 14th, with 776 tons of red molten steel carried by seven giant ladles was precisely poured into the casting mould cavity, the casting process for the front platen-a key load-bearing component of the world's largest tonnage double-action horizontal aluminum extrusion press developed by China National Heavy Machinery Research Institute Co., Ltd. (Sino-heavymach for short) was successfully completed at the casting workshop of Sinomach-he Erzhong (Deyang) Heavy Equipment Co., Ltd.(EHEC). This marks the official transition of this "national heavy equipment" from the design blueprint to the physical manufacturing phase, and represents the first major milestone in the project's manufacturing process.
Li Yong, Chairman of Southwest Aluminum (Group) Co., Ltd., led a delegation to visit the casting site. Wang Shechang, Deputy Managing Director of Sinomach-he, and Chairman of Sino-heavymach, along with Jiang Tao, Deputy Managing Director of Sinomach-he, and Qiu Mingjun, Managing Director of Sino-heavymach, were present at the production site to witness this exciting and pivotal moment. They also conducted discussions and exchanges on project progression and further collaboration.
As the world's largest tonnage double-action horizontal aluminum extrusion press, the R&D and manufacturing of this equipment face several significant technical challenges, including the design of ultra-heavy forging equipment under extreme loads, and the regulating of forming performance for limited specification castings and forgings. To ensure the high-level advancement of the project, Sino-heavymach has assembled a top-level specialized task force, by leveraging its scientific research strengths and extensive engineering application experience, and collaborating with its sister company EHEC of the extreme manufacturing capabilities, guided by customer needs, the team has established a full-process collaborative mechanism from design and development to production and delivery. The project's implementation are strictly controlled as per the quality and progress to ensure the successful realization of this major technological equipment, providing critical equipment support for building a secure and controllable industrial and supply chain.
