Microorganisms oxidize and decompose the enzymes that serve as a nutrient source for copper, promoting inactivation and reducing the number of bacteria. Additionally, when viruses adhere to copper, copper ions attempt to steal electrons from the viruses, resulting in the destruction of the virus coating and the formation of holes. At the same time, free radicals (unstable atoms or molecules lacking electrons) are generated. Since free radicals seek to steal other electrons, they accelerate the effect of reducing bacteria. This property does not diminish even if the copper changes color. *For more details, please refer to the PDF document or feel free to contact us.*

"Rolling" is a technique for processing wires, such as copper wire, by passing them between multiple rollers to flatten them (into flat rectangular wire). As the thickness decreases, the bending characteristics improve, and compared to round wire, which creates many gaps in stranded wire, it is possible to keep the wire diameter thinner while maintaining the same cross-sectional area, making it essential for miniaturization and weight reduction. The ultra-thin and ultra-fine flat rectangular wire produced by combining this technology with the drawing technology that corresponds to ultra-fine products from Meisei Industry becomes an indispensable conductor for copper foil threads, boasting some of the finest thicknesses in the world.

Thick copper wire can carry a large amount of electricity, but it is hard and difficult to bend, which limits its applications. By bundling thin copper wires, they can be made into flexible and high-capacity conductors. To achieve this, thick wire is processed through a mold called a "die" to compress its cross-sectional area to the desired thinness. This process is called "wire drawing," and it requires extensive knowledge and experience depending on the material and the target thickness.
