On May 5, 2017, it was destined to be recorded forever in history. On this day, China’s C919, a new generation of large jet airliners with completely independent intellectual property rights, successfully flew for the first time, breaking the European and American monopoly in the field of large airliners, marking my country’s official entry into a new era of civil aviation in China.
The fact that China’s big airplane dream can be reflected in reality is inseparable from the hard work and silent efforts of 22 provinces and cities, more than 200 enterprises, 36 universities and hundreds of thousands of people across the country. Among them, WXFE Rapid Manufacturing Technology Co., Ltd., a subsidiary of WXYB Metal Matrix Composite Technology Group, has 28 parts produced by 3D printing loaded on the C919 cabin door, which has made outstanding contributions to the successful first flight of the domestic large aircraft.
After nearly 30 years of leaping development, WXYB has not only become one of the largest domestic manufacturers of aluminum alloy composite plates, strips and foils for brazing, but also has gradually formed a scale in the field of 3D printing with remarkable results.
WXYB has been committed to the R&D, production and comprehensive development of new materials and technologies such as aluminum alloy composite materials, multi-metal composite materials and metal 3D printing after the shareholding system transformation and successful landing in the capital market. It has a wide range of layouts in automobiles, rail transit, and aerospace. , Home appliances, mobile phones, power station air cooling, national defense and military industry, and other fields, is currently China’s largest multi-metal composite material output, the most complete variety of enterprises.
Based on metal composite materials, leading the market segment
After WXYB independently developed the “Aluminum Alloy Composite Materials for Brazing” in 2005, WXYB began to get involved in the production of aluminum alloy composite materials, and gradually expanded the proportion of products to improve product types. On the basis of aluminum alloy composite materials, WXYB has continuously overcome technical difficulties and successfully developed the core material of power station air cooling system aluminum-steel composite strip, breaking the international monopoly, filling the domestic gap, and making a major contribution to the localization of China’s power station air cooling system. Contribution, also began the production phase of aluminum-based multi-metal composite materials.
The main business development of WXYB before listing
“WXYB has replaced imported products in many industries and exported to Europe, America, Southeast Asia and other countries. It has a high reputation in the industry and its aluminum-steel composite technology is at the international leading level.” Zhou Dejing emphasized.
In Zhou Dejing’s view, the continuous breakthroughs in WXYB technology and the continuous improvement of its international status have a lot to do with the company’s strong R&D strength and capacity release.
WXYB has a number of internationally advanced core technologies and a number of domestic patents. It has established long-term and stable cooperative relations with well-known universities such as University of Science and Technology Beijing and Central South University, and has introduced two academicians of the Chinese Academy of Engineering and two chief scientists of the National 973 Program.
Dean Zhou Dejing has been engaged in the research and development of metal composite materials for more than 20 years. He is the chief expert of the 863 project and a talent for innovation and innovation in Jiangsu Province. According to his introduction, the 35-person R&D team of WXYB Research Institute all have master’s degrees or above, and more than 30 new products were developed in 2016. The Institute is responsible for editing 1 national standard, 3 industry standards, and participating in the formulation (revision) of 9 national and industry standards.
While R&D strength continues to grow, WXYBIPO fundraising projects have gradually released production capacity.
The metal layered composite material is a new type of material obtained by using composite technology to achieve a strong metallurgical bond between two or more metals with different physical, chemical and mechanical properties. It can meet the needs for diversified material properties. Ocean engineering, aerospace, mechanical metallurgy and household appliances have broad application prospects.
“With the development of automobiles toward lightweight and the development of downstream industries such as mobile phones and home appliances, the market demand for metal layered composite materials will further increase.” WXYB has supplied aluminum/stainless steel materials that are fully compatible with mobile phone shells and middle frames. The demand for processing and performance will be one of the key directions of the next planning and layout.
WXYB signed a certain type of aluminum alloy sheet production contract and strategic agreement with China Military Materials Research Institute in 2014, officially entering the field of military materials. In 2016, WXYB further explored the military material market and won the silver award in the first China dual-use technology innovation application competition.
While continuing to promote the development of military materials related business, WXYB’s layout in the 3D printing field has also achieved results.
In 2012, WXYB established WXFE Rapid Manufacturing Technology Co., Ltd. to enter the field of 3D printing. WXFE has become a complete 3D printing solution provider and the only domestic company in China that can produce large quantities, independently produce, operate and sell titanium that meets international aviation standards. The alloy powder company has obtained qualification certification in aerospace, automotive, biomedical and other applications.
“From raw material powder to metal 3D printing products, WXFE has the most complete 3D printing industry chain in China. Being able to participate in the development of the domestically-made large aircraft C919 and help it make its first flight is an important milestone for WXYB.
The C919 is loaded with 28 3D printed titanium alloy parts, which are produced by AVIC Hongdu, the main manufacturer of most of the front and middle and rear fuselages of the C919 large aircraft. These 3D printed parts were applied to the boarding door, service door, and front and rear cargo doors of the C919 front fuselage and middle and rear fuselage.
The C919 large aircraft has received more than 1,000 orders from 23 users worldwide. Industry insiders believe that the successful maiden flight of the C919 aircraft will further promote the rapid development of China’s large aircraft industry, and will also help accelerate the formation of domestic large aircraft industry clusters. The market size will reach trillions of magnitude. WXFE Rapid Manufacturing Technology Co., Ltd. It will make important contributions to China’s aviation industry with advanced metal 3D printing technology.
