On February 23, boxes of high-end copper foil were shipped out of the factory area of Lingbao Huaxin Copper Foil Co., Ltd. (hereinafter referred to as "Huaxin Copper Foil") in Lingbao City, Sanmenxia. These copper foil products are not only used in panasonic, LG, Samsung and other foreign companies, but also can supply Tesla, BYD, Honda, to provide raw material support for electric vehicle batteries.
Since its establishment in October 2001, in the past 20 years, the annual production capacity of Huaxin copper foil has reached 25,000 tons, and the main products are 4-70 micron high-precision electronic foil, high-precision lithium battery copper foil, etc., which are used in the field of power, energy storage and digital lithium-ion batteries, supplying Tesla, BYD, Honda, Panasonic, Samsung, LG and other enterprises. "We are one of the six companies in the world that can produce 6 micron copper foil, and the national market share of high-end copper foil produced has reached 40%." Li Jichang, deputy general manager of the company, introduced.
Behind the high-quality production capacity, it is inseparable from the strong support of scientific and technological innovation. As early as October 2010, Huaxin aluminum foil established the first research center in the domestic copper foil industry specializing in the study of high-grade electrolytic copper foil, and has since established a postdoctoral research base in Henan Province and a provincial enterprise technology center, laying the foundation for the scientific and technological innovation of enterprises, and equipped with international cutting-edge copper foil special precision test equipment, which can accurately detect the physical and chemical trace elements of laboratory products and various performance indicators of products and the organic and inorganic substance content of the system solution, to meet the research and development of high-grade copper foil and various testing requirements.
In the past 5 years, Huaxin Copper Foil has invested 288 million yuan in research and development based on the R&D platform established by the company at or above the provincial level, and has overcome production technology problems such as 6 micron high tensile copper foil and 4.5 micron high resistant copper leaf.
With the intensification of domestic market competition, in order to develop high-end products with high added value and lithium battery copper foil continue to develop marketable high-grade electrolytic copper foil products to fill the domestic gap and broaden the new field of copper foil application, Huaxin copper foil 2019 to 2021 independent research and development projects 15, these projects mainly completed the copper foil preparation of production equipment upgrade research, research on high-end circuit board copper foil process, electrolyte filter material research and solution parameter optimization research, research on electrolytic copper foil cathode roller new grinding technology, Study the process formula and process parameters of ultra-thin electrolytic copper foil and optimize the formulation of special additives to improve the intrinsic properties and appearance of copper foil.
Li Jichang said that recently, Huaxin copper foil has overcome the production technology problems of 5G ultra-low profile high-frequency high-speed copper foil, which can be used in the field of 5G special electronic circuits in the future. At present, the project is under construction and is scheduled to start production in April 2022, when the annual production capacity will reach 30,000 tons.
