    • In a method of making an ornament, a metal ornament body (1) having an internal groove (7) opening at one end (7a) to an end edge of the metal ornament body (1) and at an opposite end (7b) to front and rear surfaces of the metal ornament body (1) is held between two relatively movable mold members (9, 10) while the one end (7a) of the internal groove (7) is connected to a gate (13) of the mold members (9, 10) and the oppo­site end (7b) of the internal groove (7b) communicates with mold cavities (11a, 11b) in the mold members (9, 10). Then, a melted synthetic resin material is in­jected into the mold cavities (11a, 11b) through the gate (13) and the internal groove (7). Since the gate mark is not formed on the outside surface of an orna­mental member (2) molded of synthetic resin but left on the end edge of the metal ornament body (1). The gate mark thus formed is normally hidden from view and does not deteriorate the aesthetical appearance of the ornament.
    • 在制造装饰品的方法中,金属装饰体(1)具有在一端(7a)的一端(7a)向金属装饰体(1)的端边缘开口的内槽(7)和相对端(7b)至 金属装饰体(1)的前表面和后表面被保持在两个可相对移动的模具构件(9,10)之间,而内凹槽(7)的一端(7a)连接到模具的浇口(13) 内槽(7b)的构件(9,10)和相对端(7b)与模具构件(9,10)中的模腔(11a,11b)连通。 然后,熔融的合成树脂材料通过浇口(13)和内槽(7)注入模腔(11a,11b)中。 由于栅极标记没有形成在由合成树脂模制而是留在金属装饰体(1)的端部边缘上的装饰件(2)的外表面上。 由此形成的门标通常隐藏起来,并且不会使装饰品的美学外观恶化。
