A manufacturing method for a sign board is provided to realize the repetitive manufacturing and the manufacturing of small amount into the different shape for one process. A manufacturing method for a sign board includes the step for drawing the design; the step for fabricating a metal mold; the step for tightly assembling; the step for molding the sign board; the step for sampling the sign board. In the metal mold fabricating step, an inside mold(30) and an outside mold(31) are manufactured by cutting the die material along the designed pattern. The size is controlled to form the space(32) between the bottom part and both side walls, when the inside mold piles up with the outside mold. |
