The refined copper is then cast into billets or ingots, which serve as the starting point for wire drawing. Ensuring consistent chemical composition and purity at this stage is critical, as it directly influences the electrical conductivity and overall performance of the final product.

Forming: Drawing and Annealing

The primary shaping process involves wire drawing, where copper billets are progressively pulled through a series of dies to achieve the desired diameter and mechanical properties. This process is performed in multiple stages, often with intermediate annealing steps to restore ductility lost during drawing. Annealing involves heating the wire in controlled atmospheres (such as inert gases) to soften the copper, making it more pliable for further drawing without cracking or breaking. Precision in controlling temperature, drawing speed, and die wear is vital to maintain dimensional accuracy and surface quality.

Assembly and Surface Treatment

Once the copper wire reaches the targeted gauge, it undergoes surface inspection and cleaning to remove any residual lubricants, oxides, or surface imperfections. Some manufacturers apply additional surface treatments—such as electro-polishing or passivation—to enhance surface smoothness and corrosion resistance, even if the wire is intended to be used without enamel. These steps help improve solderability and reduce defects during subsequent manufacturing or assembly processes. For specific B2B applications, the wire may be wound onto spools or coils under controlled tension to prevent deformation or surface damage.

Finishing: Quality Control and Packaging

The finishing stage involves stringent quality checks before packaging. The wire is inspected for dimensional accuracy, surface quality, and mechanical integrity. This includes measuring diameter tolerance, surface roughness, and tensile strength. After passing inspection, the wire is spooled or cut into specified lengths, then packaged in moisture-proof, anti-corrosion materials suitable for international shipping.
