Wire drawing is a cold-forming process that involves reducing the diameter of the wire by pulling it through a series of dies. This operation not only changes the physical dimensions of the wire but also improves its mechanical properties, such as tensile strength and ductility. The wire drawing process is typically carried out in multiple stages, with each stage contributing to the final product’s specifications.<\/p>\n
