The copper foil industry belongs to the copper processing industry, which processes copper into extremely thin copper strips or sheets by means of rolling, electrolysis and sputtering, and further applies them as industrial raw materials in various downstream products. The thickness of μ Below m, the thickness varies depending on the scene used.

Although the thickness of copper foil gradually becomes thinner, power battery manufacturers use 6 μ When the product is less than or equal to m, the coating machine, winding machine and other key equipment as well as the technological level cannot solve the problems such as wrinkles, belt breakage and high-temperature oxidation encountered in the production process, which leads to the inability to mass produce ultra-thin copper foil with high yield.

Backward key production equipment: for high-quality products with production thickness less than 0.05mm, multi roll rolling mill with width meeting user requirements shall be used. The rolling mill of some domestic copper processing plants can not be normally put into rolling foil production due to the lack of other equipment or the traditional product structure in the factory. However, some small processing plants have to use outdated production equipment and processes due to lack of key equipment or investment capacity, and copper foil product specifications and technical indicators are inferior to foreign products.
