Abstract

PURPOSE: To enable a plastic sheet or the like to be molded into a desired shape without damaging a fine relief pattern previously arranged on its surface, by clamping the sheet by a pair of female and male molds that also serve as high-frequency electrodes, and carrying out dielectric heating at a specified step.
CONSTITUTION: A pair of mating molds comprise the male mold 1 and the female mold 2 that also serve as high-frequency electrodes, and a plastic sheet, or plate, thermoplastic synthetic leather element or the like is clamped between the mating molds. In the step wherein the projection of the male mold 1 enters the recess of the female mold 2, and the top surface of the male mold 1 and the bottom surface of the female mold start to clamp the sheet or the like, dielectric heating is carried out, then the dielectric heating is stopped, and the projection of the male mold is forced into the male mold so that the top surface of the male mold and the bottom surface of the female mold further clamp the plastic sheet or the like.
