China's metal 3D printing technology favored by multinational corporations

Huazhong University of Science and Technology metal 3D printing technology by multinational companies of all ages. Following the General Electric expressed his intention of team cooperation and acquisition with the school Zhang Haiou, Airbus also take the initiative to come. Recently, Huazhong University of Science and Technology and Wuhan Tian Yu Intelligent Manufacturing Co., Ltd. signed a cooperation agreement to announce the formal cooperation in the field of aviation industry.

Based on the powerful platform of Huazhong University of Science and Technology, the team of Professor Zhang Haiou independently developed the micro-casting and forging composite equipment after more than ten years of painstaking research and creatively combined metal casting and forging technology to achieve the world's leading The original innovation of the micro edge casting. The result broke the biggest obstacle in the 3D printing industry and changed the traditional manufacturing history of "casting, separating and milling", which has long been led by the West. The new technology significantly improves the strength and toughness of parts and improves the fatigue life and reliability of components. At the same time, the cost of the traditional giant forging press is eliminated, and the forming path can be directly controlled by the computer, not only the thin-wall metal parts can be printed, but also the equipment investment and the raw material cost are greatly reduced. Particularly gratifying is that through the production of such parts of micro-casting forging, the technical indicators and performance are stable than the traditional forgings.

Professor Zhang Haiou team successfully developed the technology, did not let the technology lying in the laboratory "sleep big", but through the establishment of industrial base - Tianyu company for technology transformation and promotion. "Intelligent micro-casting forging milling composite manufacturing" has been applied to the development of new products of XAC, Xi'an Airlines and China Southern Power Company, trial production of high temperature alloy double-twisted impeller, aluminum-silicon alloy heat pump body, engine transition section And other parts, as well as large-scale aircraft skin pressing double-curved mold, car fender stamping forming FGM molds.

Zhang Haiou told science daily reporter, and Airbus to start technical cooperation, the purpose is to provide airbus product manufacturing services to prepare. Some experts said that the cooperation with the world's industrial aviation giant will further promote the development of China's high-end manufacturing industry. (Reporter Liu Zhiwei)
