Surface preparation: The surface of the aluminum perfume caps is cleaned and treated to remove any impurities, oils, or other contaminants that may interfere with the dyeing process.
Dye preparation: A dye solution is prepared, which typically consists of a mixture of dyes, water, and other chemicals such as surfactants or leveling agents. The specific dye mixture will depend on the desired color of the caps.
Dye application: The dye solution is applied to the surface of the aluminum perfume caps through a variety of methods, including dipping, spraying, or brushing. The caps may be heated or exposed to UV light to help the dye adhere to the surface.
Rinse and dry: Once the caps have been dyed, they are rinsed to remove any excess dye and then dried. The drying process may involve air drying, heating, or using a vacuum or other specialized equipment.
Sealant application: In some cases, a sealant may be applied to the dyed caps to protect the color and enhance the durability of the finish.
