GRM Precision Copper Flat Wire Machine is an integrated production line for manufacturing high-precision copper flat wire used in magnet wire, transformer conductors, CTC conductors and EV motor applications. The line combines wire drawing, precision rolling, online measurement, polishing, dust collection and automatic take-up into one continuous process.
Designed by Jiangsu Goodroller Machinery Co., Ltd. (GRM), this system helps manufacturers improve production efficiency, reduce manual handling and maintain stable dimensional consistency during long production cycles.
GRM can customize the production line according to input wire diameter, finished flat wire size, material requirements and downstream application needs.

GRM uses CNC machining centers, laser precision tools and automated production systems to support stable equipment manufacturing. The engineering team provides process consultation, 3D modeling, customized line design and technical support based on customer production requirements.
Yes. The line is suitable for transformer conductors, magnet wire, CTC conductors and other electrical copper flat wire applications.
Yes. GRM can customize the machine configuration according to inlet wire diameter, finished wire dimensions, tolerance requirements and production capacity.
The system can achieve thickness tolerance up to ±0.005 mm and width tolerance up to ±0.01 mm under suitable production conditions.
Compared with separate machines, an integrated line reduces material handling, improves production continuity and helps maintain more stable dimensional consistency.
