SYNTHETIC RESIN STEREOSCOPIC DECORATIVE PIECE AND METHOD OF MANUFACTURING THE SAME

摘要

There are provided (1) a method of manufacturing a three-dimensional decoration piece having a flat rear surface, (2) a method of manufacturing the decoration piece by easily cutting the same by means of a fusion cutter, (3) a method of manufacturing the decoration piece having a bonding or sticking feature on the rear surface and (4) a method of manufacturing a three-dimensional decoration piece without limiting the characteristics of the base member thereof. The three-dimensional decoration piece is manufactured by using an indented mold (32) and high frequency dielectric heating. An indented mold (132) having a second fusion cutter (152) and arranged along an outer periphery of the fusion cutter (151) is used. Firstly, a three-dimensional molded body (216) of upper and intermediate layers having a recessed section (244) on a lower surface thereof is molded by means of an indented mold (232) and a protruding mold (216), and subsequently a lower layer material (213) is molten by high frequency dielectric heating and made to flow into the recessed section. Firstly, a three-dimensional molded body (316, 416) of upper and intermediate layers is molded, and subsequently the three-dimensional molded body is welded to a base member (414) by means of high frequency dielectric heating.
