What is the function of High-Precision Micro Flat Wire Rolling Mill

      The High-Precision Micro Flat Wire Rolling Mill is the core equipment for continuously rolling round wire into micrometer level precision flat wire/irregular wire in cold state. Its core function is high-precision forming, efficient continuous production, stable material properties, and adaptability to high-end manufacturing. It is a key equipment in the fields of flat wire motors, precision electronics, medical, automotive, etc.

1、 Core Function (Function)

1. Cross section precision molding (core)

      Round to Flat/Irregular Conversion: Copper, aluminum, stainless steel, titanium alloy and other round wire rods are continuously rolled by multi pass precision rollers to accurately press into rectangular, square, trapezoidal, rounded flat wire and other cross-sections.

      Micron level size control: The thickness accuracy can reach ± 0.003-0.005 mm , the width accuracy is ± 0.005-0.01 mm , and the rounded corner R angle is uniform and consistent.

      Alternative to traditional processes: higher efficiency than stretching and molding, no mold loss, and better surface quality.

2. Continuous and efficient production

      High speed continuous rolling: The line speed can reach 200-500 m/min, suitable for large-scale and large-sized wire production.

      Multi pass continuous rolling: rough rolling+precision rolling+edge shaping integrated, one-time forming, reducing intermediate processes.

      Online closed-loop control: AGC automatic thickness control, servo roller gap adjustment, online thickness/width measurement, real-time correction, high consistency.

3. Material performance optimization

      Cold work strengthening: Rolling refines grains, increases density, and significantly improves strength, hardness, and wear resistance (such as increasing the strength of copper flat wire by more than 30%).

      Surface quality improvement: Hard alloy roller+precision grinding, surface smoothness Ra ≤ 0.05 μ m, no scratches, no oxidation, no burrs.

      Straightness and flatness: Rolling+online straightening, the straightness can reach 0.5 mm/m, and the flatness of the flat line is high, making it easy for subsequent winding, welding, and assembly.

4. Adapt to high-end application scenarios

      Flat wire motor winding: High duty cycle flat electromagnetic wire is used for motors in new energy vehicles, industrial servos, and drones to improve efficiency and reduce temperature rise.

      Precision electronics/connectors: ultra-thin copper flat wires, pins, and spring clips for mobile phones, wearable devices, and PCBs, with integrated conductivity and structure.

      Medical/Precision Instruments: Interventional catheters, surgical instruments, memory alloy (NiTi) flat wires, biocompatibility+high precision.

      Automotive components: wiper blades, scroll springs, sensor spring plates, wire harness terminals, high-strength and corrosion-resistant.

      Photovoltaic/charging station: high current flat wire, busbar, low loss, high heat dissipation.

2、 Key technical features (supporting role implementation)

      Precision rolling mill: made of hard alloy (YG8/YG15), with a true roundness of <0.001 mm and a surface Ra of ≤ 0.02 μ m, it has a long service life and good precision maintenance.

      Servo control: dual servo+planetary gear+precision screw, roller gap adjustment resolution of 0.001 mm, parallelism <0.002 mm .

      Tension closed-loop: Stable control of front and rear tension ensures uniform rolling, no tensile deformation, and dimensional stability.

      Online detection: laser thickness/width measurement, CCD vision, real-time feedback adjustment, finished product qualification rate >99% .

      Multi material adaptation: capable of processing copper, aluminum, stainless steel, titanium, nickel titanium, brass, etc., covering the vast majority of precision wire requirements.
