Abstract
A multi-face part is provided on a half-finished product which eventually becomes a metal decorative button. The multi-face part includes a plurality of small sectional faces and ridges obtusely joining between two adjacent small sectional faces. An outside of the half-finished product including the multi-face part is plated. Then, the half-finished product is barrel-polished. Thereby, the plating on portions corresponding to the small sectional faces remains and the plating on portions corresponding to the ridges is removed, exposing the ground color of the half-finished product. Then, the multi-face part is partially compressed to form the metal decorative button having a compressed decorative surface. The compressed decorative surface is given a pattern composed of a plurality of small sectional parts corresponding to the small sectional faces with the plating left and boundaries corresponding to the ridges with the plating removed.
