Preparation of dial for clock

Abstract

Abstract PURPOSE:To secure stable quality inexpensively and simply, by forming a painting layer on a dial substrate and transferring the pattern of a mold to the painting layer by pressure and an ultrasonic wave. CONSTITUTION:Painting is applied to the upper surface of a dial substrate 1 to forme a painting layer 2. The dial substrate 1 having the painting layer 2 is set to the main body frame 9 of an ultrasonic processing machine and, when compressed air is introduced from an air port 8 to allow a cylinder 6 to fall, the carved surface 5A of a pattern mold 5 is closely brought into contact with the painting layer 2. By applying an ultrasonic wave to a horn 4 from an ultrasonic wave generator 4A in this state, the pattern of the carved surface 5A is transferred to the painting layer 2.
