Rectangular copper wire, also known as flat copper wire or rectangular magnet wire, plays a critical role in motors, transformers, and high-efficiency electrical equipment. Its space-saving shape allows more copper to fit into winding slots compared to round wire, improving electrical conductivity, reducing resistance, and enhancing thermal performance. In this article, we’ll explain how rectangular copper wire is produced and why precision manufacturing is essential for top performance.

A Square Bar Rolling Machine is a type of metal forming machine designed to convert round wire, flat wire, or raw metal rods into perfectly shaped square profiles. This machine uses a series of precision rollers that apply controlled pressure to gradually shape the material into square form with exact dimensions and a smooth surface finish.
There's nothing like seeing the final result with your own eyes.
