Abstract

PURPOSE: To inexpensively produce a dial plate and panel cover for timepieces having multiple patterns possessing three-dimensional feel by transferring the rugged patterns of a blank material to an electrotyping sheel of rigid metal by an electrotyping method, and embossing the dial plate and panel cover by using this shell.
CONSTITUTION: First, a recess 7a is provided by machining, etching or the like on the surface of an electrotyping jig 7 of a BS material, and a pattern A is given to the top surface excluding the recess 7a by mechanical or chemical means, whereby an electrotyping matrix is made. Next, Cu electrotyping is carried out on this matrix to reversely manufacture a Cu mold 8. A pattern B is given to the top surface of the convex part 8a formed by reversing the recess 7a by mechanical or chemical means, and a difference in stage from the pattern A is given to said pattern. Next, with the Cu mold 8 as a matrix, electrotyping of rigid metal is carried out to manufacture a finished die 9. The die 9 is secured into the upper die 11 of an embossing type by mechanical or chemical method and a dial plate or panel cover 10 is inserted between the famale die 13 containing urethane rubber 12 and the male die 11, and is then embossed, whereby two kinds of patterns A, B are applied on the surface of the plate 10.
