These products are produced through cold drawing operations, aimed at achieving highly precise diameters and smooth, uniform surfaces, along with changing the mechanical properties of the bars. The raw material moves through a drawing die to the desired size. As a result of the drawing process material is strengthened which means increase in tensile strength and decrease in elastic properties. Following the cold drawing process, the bars are placed in a straightening machine to remove any bending. After straightening and quality control, the products are transferred to the packaging line.”
