The business relies on the material technology research and development center of CRRC Qishu Yan research and development production. The material technology Research and Development Center of CRRC Qishuyan Institute is a first-level research and development institution directly managed by Qishuyan Institute, currently under the jurisdiction of 12 professional disciplines. Among them, there are 103 R&D personnel, including 5 national senior technical experts, 1 senior skill expert, 15 provincial and ministerial technical experts, 23 senior engineers, 4 doctors, 85 masters. It has more than 100 sets of various research and development equipment and fixed assets of nearly 1.5 billion yuan.

Our company has a mature "3D printing + casting" service capability to provide rapid manufacturing services for key parts of rail transit, and has expanded to the development of key parts in aerospace, automotive, construction machinery and other fields. There is no need for traditional mold production, with high degrees of freedom in design and manufacturing, and can produce sand shapes of complex shapes, which can effectively simplify the production process and shorten the development cycle. At this stage, sand 3D printing is mainly used in the new casting process setting and the rapid development of single (multiple) casting products.

This business segment of our company has a number of 3D printers using different technologies, which can cover complex structures with film sand/core, and the film sand/core can be used for gravity casting of cast steel, cast iron, aluminum magnesium alloy and other castings, and the dimensional accuracy and surface quality of the castings are better than the traditional casting methods. The additive technology has three main features:
01 Large-scale: to achieve the printing of type/core products within the length range of 1.5m;

02 Fine: It can realize the fine molding of the product mm slot and hole structure;

03 Integration: It can realize the printing and molding of complex structural parts integrating multiple functions.
