    • There are provided (1) a method of manufacturing a three-dimensional decoration piece having a flat rear surface, and (2) a method of manufacturing the decoration piece having a bonding or sticking feature on the rear surface.
      A method of manufacturing a three-dimensional decoration piece made of synthetic resin, wherein
      laying an intermediate layer material (212) of a thermoplastic synthetic resin and an upper layer material (211) of a thermoplastic synthetic resin on a protruding mold (233) of cathode;
      pressing the layers material from above by an indented mold (232) of anode, to melt and mold the materials by high frequency dielectric heating, so as to form a three-dimensional molded body (216), said molded body (216) being formed with a recessed section (244) on a lower surface thereof, said molded body (216) being temporarily anchored to the indented mold (232);
      pulling up the indented mold (232) with the molded body (216);
      laying a lower layer material (213) having a bonding or sticking feature on a cathode (234) having a flat surface;
      lowering the indented mold (232) onto the cathode (234) to press the layer materials; and
      melting the lower layer material (213) by high frequency dielectric heating, so that the lower layer material (213) flows into the recessed section (244), so as to weld the molded body (216) and the lower layer material (213).
    • 提供(1)制造具有平坦后表面的三维装饰件的方法,以及(2)制造在后表面上具有粘合或粘附特征的装饰件的方法。 一种制造由合成树脂制成的三维装饰件的方法,其中将热塑性合成树脂的中间层材料(212)和热塑性合成树脂的上层材料(211)铺设在突出模具(233)上的 阴极; 通过阳极的凹陷模具(232)从上方压制层材料,以通过高频电介质加热熔化并模制材料,从而形成三维模制体(216),所述模制体(216)形成 在其下表面上具有凹陷部分(244),所述模制主体(216)暂时锚定到凹进模具(232); 用模制主体(216)拉起凹进的模具(232); 在具有平坦表面的阴极(234)上铺设具有粘结或粘附特征的下层材料(213) 将凹陷模具(232)下降到阴极(234)上以压制层材料; 通过高频电介质加热使下层材料(213)熔融,使下层材料(213)流入凹陷部分(244),从而焊接成型体(216)和下层材料(213) )。
