Introduction to the manufacturing process of copper foil thread like a string.

Challenging the ultimate in fine, thin, and short! Introducing the manufacturing process of thread-like copper foil.

We would like to introduce the manufacturing process of "copper foil wire" that we handle. "Wire drawing" is the process of stretching round copper wire using a die. The drawn copper wire then undergoes the "rolling" process, where it is shaped into foil using a rolling machine. After that, in the "foil winding" process, the foil is wound onto the wire. Meisei Sangyo refines its unique technology to achieve thin, light, and short products. 【Manufacturing Process】 1. Wire Drawing: The process of stretching round copper wire using a die. 2. Rolling: The process of shaping the drawn copper wire into foil using a rolling machine. 3. Foil Winding: The process of winding the foil onto the wire. *For more details, please refer to the PDF document or feel free to contact us.
