What are the uses of Rectangular Wire Micro Rolling Unit

      Overall function: Roll circular copper wire, aluminum wire, stainless steel, and nickel titanium alloy round wire into thickness width controllable rectangular flat wire through cold rolling, achieving micrometer level dimensional accuracy and producing high-precision rectangular conductors and precision profiles.

1、 New energy industry (primary use)

Photovoltaic field: Rolling photovoltaic welding strips, converging flat copper strips, producing 0.12-0.3mm ultra-thin rectangular copper flat wires; Ensure the welding strip is straight, reduce hidden cracks in the battery cells, and adapt to TOP-Con and N-type photovoltaic modules.

New energy vehicles and energy storage equipment

Rolling Hair Pin flat wire motor winding wire, used for 800V high-voltage drive motors, energy storage reactors, and internal conductive discharge of flow batteries; Rectangular wire has a higher filling rate and better heat dissipation compared to circular wire slots, reducing coil heating and improving motor energy efficiency.

Produce high-voltage connectors and rectangular conductors inside sensors.

2、 Electrical motor industry

Rolled enameled rectangular copper flat wire, used for industrial servo motors, wind turbines, transformers, and charging station coils; Control the tolerance of R angle, thickness, and width to ensure the quality of later enamel processing.

Rectangular conductor substrate for transposed wires and dry-type reactors.

3、 3C electronic and communication components

Producing ultra-thin rectangular wires for connector spring plates, inductors, micro motors, and relay contact plates; Rolled nickel plated copper wire and silver plated copper wire, with a smooth and burr free surface, suitable for micro wiring inside mobile phones, base stations, and circuit boards.

Precision lead frame raw materials.

4、 Precision Hardware and Spring Industry

Rolling stainless steel and high carbon steel rectangular flat wire, used to manufacture spiral springs, wiper blades, saw blade substrates, and precision snap springs; After rolling, the internal stress of the material is uniform, and it is not easy to break during later stamping and bending, with stable elasticity.

Produce precision component substrates for automotive sensors and braking systems.

5、 Medical and high-end special materials fields

Rolling nickel titanium alloy and medical stainless steel rectangular micro wire, used for dental orthodontic wires, minimally invasive surgical guide wires, and implant components; Strictly control surface smoothness to meet medical grade requirements.

6、 Other application areas

Aerospace: titanium alloy, nickel based alloy rectangular profiles, producing lightweight structural components;

Precious metal processing: gold and silver rectangular wire, used for jewelry and precision instrument parts;

Ordinary industry: sealed flat strips, heat dissipation and exhaust materials.
