The non-ferrous metal is made of a very lightweight metal material such as nickel, aluminum, magnesium and cadmium, but aluminum is used in the present invention.

Subsequently, the molded body of the button was cleaned, electrolytic (electrolytic) work was carried out in which an electric current was passed through an electrolytic bath containing a sulfuric acid electrolytic solution to form an anodic oxide film on the surface of the molded body.

In the electrolysis step, when a current flows into an electrolytic cell (electrolytic cell) containing a sulfuric acid solution with an aluminum plate as an anode, oxygen is generated on the surface of the aluminum plate by the charge (charge) generated at this time to form a thick oxide film, The oxide film is formed of a porous and fibrous material, so that not only the penetration of the dye but also the electrical insulation is high, and the oxidation film having good corrosion resistance and abrasion resistance is formed.

Subsequently, a dyeing step of applying a dye to the anodized film formed of a porous material and applying a color thereto was carried out.

Then, the button molding completed with dyeing was transferred through the conveyor of the drying furnace, and a drying operation was performed by heat-treating at a temperature of 60 to 75 캜 to complete the production of the non-ferrous metal button.

The non-ferrous metal button completed by the above-described manufacturing process is very light in weight, so that when the fabric is hanged on the clothes, it is prevented from being closed due to sagging of the fabric and dyed in various colors to maintain the appearance of the button beautifully, Thus, it is possible to realize a high quality button having good corrosion resistance and abrasion resistance.
