The second phase of the main project planning and construction of aluminum-magnesium alloy die-casting workshop, machine shop, finishing shop, surface treatment shop, test center, research and development technology center, storage and logistics center. Among them, the aluminum-magnesium alloy die-casting workshop plans to build 27 domestic first-rate aluminum-magnesium alloy die casting machines, and 50 sets of fully-digital controlled CNC machine tools are planned in the machine shop, and a full-automatic green production line is planned and constructed for the finishing and processing workshops. The test center planning and construction can meet the provincial test and test center for all test requirements of automobile assembly manufacturers. The entire project has high construction standards and covers a wide range of projects, including all functions such as R&D, production, testing and warehousing of new aluminum-magnesium alloy materials. It will establish a leading R&D and production base for new materials in the province.
