Thick copper wire can carry a large amount of electricity, but it is hard and difficult to bend, limiting its use. By bundling thin copper wires, you can make a supple and high-capacity conductor. For that purpose, a thick wire is passed through a mold called a “die” to compress the cross-sectional area and process it to the desired fineness. This is “drawing”.
A wire drawing that requires a lot of knowledge and experience depending on the material and the desired fineness. At Meisei Sangyo, we manufacture ultra-fine conductors by utilizing the knowledge of skilled craftsmen, the skill of craftsmen who pass wires through 10 μm dies, and various equipment.
