High precision copper foil as thin as a cicada's wings, high-end materials used in the new display industry, and laser composition analyzer capable of detecting material composition... At the 2022 World Manufacturing Conference, a group of "little giant" enterprises specializing in special new technologies brought their own "black technology" and new products, adding new vitality and new momentum to the development of the manufacturing industry. (The picture shows the venue of the 2022 World Manufacturing Conference.) Walking into the Hefei Binhu International Convention and Exhibition Center, the exhibition hall of this conference has a sense of science and technology in tens of thousands of square meters of space. At the booth of Tongling Huachuang New Materials Co., Ltd., rolls of thin, shiny, silky copper foil attracted many people. "I didn't expect that the heavy metal copper could also be processed to be thinner than hair and thinner than paper." A visitor gave a thumbs up and said, "It's amazing!"! "Copper foil is an important material for the production of power batteries for new energy vehicles." Xu Yifan, a booth staff member, said that the company was committed to the research, development and production of high-end materials, and its order growth was stable. In 2021, the company was recognized as a "small giant" specializing in special new products. (The picture shows Xu Yifan displaying copper foil.) Specializing in special new enterprises, especially the "little giants" specializing in special new enterprises, are the new force to promote the high-quality development of manufacturing industry and play an important role in ensuring the stability of the industrial chain supply chain and promoting social and economic development. At the booth of Anhui Hechen New Materials Co., Ltd., several round black mats attracted everyone's attention. "These are adsorption pads and polishing pads. Although they are dark, they are necessities in the new display industry chain." Xu Cheng, the booth staff member, picked up the mat to introduce to the reporter that these products used to rely mainly on imports. The enterprise broke the technological monopoly through the cooperation between industry, university and research. At present, the adsorption mat products produced by the enterprise rank at the forefront of the domestic market share. The company also became a specialized and new "little giant" enterprise in 2021. The "race track" of the "little giant" enterprises specializing in special and new technologies is very different, and their growth paths are also different, but the soul lies in innovation. Luo Junzhang, deputy director of China SME Development Promotion Center, said that R&D investment and innovation capability have become key indicators to measure the core competitive advantage of enterprises. At present, China's "little giant" enterprises specializing in special and new technologies have set up more than 600 national R&D centers, holding more than 140000 invention patents in total, providing strong support for promoting high-quality development. A good industrial ecology is inseparable from the leading role of large enterprises and the supporting support of small and medium-sized enterprises. At this conference, Hefei Jinxing Intelligent Control Technology Co., Ltd., a specialized and special new "little giant" enterprise, brought several laser component analyzers. The round and smooth shape attracted the attention of many viewers. "These machines not only have a high 'face value', but also have a higher 'IQ'." Liu Wenxiang, a staff member of the company, said that the laser composition analyzer can quickly detect the composition of materials, without sampling and sample preparation, and the test results can be synchronized to the data platform. At present, these instruments have been widely used in large enterprises in nonferrous metals, steel, electricity and other fields to help enterprises build digitalization and intelligence. Growing from an ordinary small and medium-sized enterprise to a "small giant" requires joint watering and cultivation by many parties. At the conference, Anhui Tianzhu
