The journey of a metallic gold zipper begins with the selection of high-quality materials. The base of the zipper is typically made from durable metals such as brass or aluminum. These materials are chosen for their strength and ability to withstand wear and tear. Once the metal is selected, it is cut into the desired shapes for the zipper teeth and slider. This initial step is crucial, as the precision of the cuts will affect the functionality and aesthetics of the final product.
