摘要： A plastic molding, such as a key top with signals or letters appearing on its face, has a first part molding having projections formed at its top defined an enclosed area. A second part molding of a color other than that of the first part molding is adhered to the surface of the first part molding in a manner permitting the ends of the projections to be exposed. The first part molding has a plurality of through holes formed in mesh configuration. At least one of the projections corresponds to at least one of the through holes. The second part molding is adhered to the first part molding to be buried in the plastic material of the second part molding. Part of the plastic material of the first part molding is filled into the enclosed area via the through holes. In a method of making such plastic molding, an inner member of the mold die may be used commonly regardless of the sign or letter provided in the plastic molding.

摘要翻译： 诸如具有出现在其表面上的符号或字母的键顶的塑料模制件具有形成在其顶部上的突起的第一部分模制件，其限定封闭区域。 以第一部分模制品以外的颜色的第二部分模制件以允许突出部分的端部露出的方式粘附到第一部分模制件的表面。 第一部分模制件具有形成为网状构造的多个通孔。 突起中的至少一个对应于至少一个通孔。 第二部分模制件粘附到第一部分模制件上以埋在第二部分模制品的塑料材料中。 第一部分模制件的塑料材料的一部分通过通孔填充到封闭区域中。 在制造这种塑料模制的方法中，可以通常使用模具的内部构件，而不管塑料模制件中提供的符号或字母如何。
