Method of making patterns for decorative piece

摘要

A method of making patterns for decorative piece, comprising the steps of using a metal plate as the molding substrate for laser etching, placing the mold substrate under a laser etching device for being cut by a laser beam, grooving repeatedly and radiately on a certain position level by level via different emitting diameters to form a recession with a first depth, thereafter repeating the afore-mentioned processing after removing the laser head (including the prism set) a distance, accomplishing pluralities of mold grooves averagely distributed on a surface of the mold substrate, and proceeding with plastic injection and forming tiny pins on the plastic decorative piece.
