The copper wire flattening mill is designed for precise shaping and dimensional control of round copper wire into flat or rectangular profiles. The system typically accommodates pure copper wires, including high-conductivity grades such as Cu-ETP (C10100) and Cu-OF (C10200). Wire diameters entering the mill typically range from 0.2 mm to 3.0 mm, with output thicknesses from 0.1 mm to 1.5 mm and adjustable widths depending on the rolling passes and die configuration.
The CRM Pure Copper Wire Flattening Mill consists of several core components designed to ensure accurate and stable material deformation. The rolling unit carries out the forming process with precisely aligned rolls, while the drive system provides smooth and synchronized operation. In the copper flat wire industry, this machine is mainly used for the production of enameled flat wire, paper-insulated transformer conductors, and flat wire products for motor applications.
The wire payoff machine is designed to accommodate the customer’s raw material packaging. Typical configurations include I-beam reel feeders and coil wire feeding machines.
The intermediate drawing machine reduces a Ø12 mm oxygen-free copper rod to an output diameter of approximately Ø3 mm. This multi-stage drawing process ensures precise control of wire dimensions and surface quality
We have installed tension control dancers between the wire drawing machine and the rolling mill. Their function is to precisely control wire tension, compensate for variations in drawing speed, and maintain consistent material feed…
The rolling mill is used to deform oxygen-free copper round wire into flat wire through a controlled rolling process. Precisely aligned rolls and optimized reduction schedules ensure accurate thickness
The edger rolling mill is installed downstream of the main rolling mill stand. Its function is to precisely control the flat wire width, correct edge deformation, and improve edge straightness, thereby enhancing overall dimensional accuracy and surface quality.
The wire winding machine actively winds the finished enameled flat copper wire onto reels or spools with controlled and consistent tension, It is suitable for flat copper wires with typical dimensions ranging from 0.5–6.0 mm in thickness and 2–30 mm in width,
The Model CRM2026—QB is a complete copper wire precision rolling mill production line. The equipment primarily consists of a horizontal traversing payoff machine, drawing stand, Ø200 mm rolling stand, dancer system, Ø150 mm edger mill, brushing machine, automatic gauge control system, and spool take-up system. It provides a fully integrated solution for high-precision wire flattening machine process, ensuring one-stop manufacturing of flat copper wires.
