June 29th News Ultra-thin aluminum foil is widely used in food packaging, cigarette paper, cosmetics and other industries, but the production process is extremely complicated. Sino-US joint venture Yunnan Xinmei Aluminum Foil Co., Ltd. breaks through the traditional process of producing ultrabook aluminum foil with 480 to 520 millimeters of hot rolled coils in the world. It has taken the lead in the domestic and international production of self-produced cast blanks for batch production of super-owned intellectual property rights. The thin-gauge aluminum foil forms a complete set of process technology system, which has subverted the traditional understanding of aluminum foil production concepts at home and abroad, and has made important contributions to the development of the aluminum foil industry in China. Recently, the company has obtained 4 authorized patents, and has become China's ultra-thin "Electronics, electricity, capacitors with aluminum foil," the national standard compiler.
According to the company’s general manager, Gao Yan, China’s aluminum foil production exceeded that of the United States in 2005 and became a primary aluminum foil powerhouse. However, about 60% of them are used for air-conditioning and other thicker heat-dissipating products, and the production of double-null foils representing the production technology level of aluminum foil is only about 110,000 tons, and some of the high value-added products such as 0.0045mm and 0.005mm are all zero-thin and ultra-thin Aluminum foil is all dependent on imports. Since 2004, the company has imported hot-rolled aluminum billets from foreign countries to produce double-zero aluminum foil, which has high costs and low output and cannot compete with foreign companies. Since 2006, with the support of the Yunnan Provincial Science and Technology Department, the company has carried out the project technology research on the “key technology for the production of double-zero aluminum foil for cast blanksâ€, trying to use self-produced cast blanks as raw materials, around the relevant high-efficiency and environmental protection. The key technologies for narrow-area control of alloy composition, homogenization of cast-rolled billets, and optimization of rolling have been independently researched and developed to produce high-quality, low-cost double-zero ultrathin aluminum foil.
According to expert appraisals, this product fills the gap in China, replaces imports, and achieves volume export. The product quality has reached the international advanced level of producing similar products with the hot rolled blank process, and will further promote the miniaturization and weight reduction of China's electronic components.
In 2008, the company added 11012 tons of double-null foil, including 806 tons of ultra-thin aluminum foil of 0.0045 mm and 0.005 mm, new production value of 323.58 million yuan, and an additional export of 2.18 million yuan. At present, the company has obtained stable overseas orders from General Electric of America, Cooper of USA, and ABB of Australia, becoming the only company in China that has obtained the qualification of capacitor aluminum foil supplier of General Electric of the United States, and has been awarded the Chinese aluminum foil by China Non-ferrous Metal Processing Industry Association. Top ten companies.
