    • A method and device for making integrally formed one-piece molded parts is provided, where the molded parts are to contain a void within their volume. An exemplary such molded part is an arc tube for a discharge lamp. A wax core is first molded onto a core pin wire in the shape of the desired void, the discharge chamber in the case of an arc tube. Then the part is molded over the wax core to provide an integrally formed one-piece part having the appropriately dimensioned void volume therein defined by the wax core. After the part has been hardened around the wax core, the core is removed by conventional means. The holes through the finished molded part left after the core pin wire is removed can be filled in, or in the case of an arc tube they are useful as passageways to accommodate electrodes therethrough.
    • 提供一种用于制造一体成型的单件模制件的方法和装置,其中模制部件在其体积内容纳空隙。 示例性的这种模制部件是用于放电灯的电弧管。 蜡芯首先以所需的空隙的形状被模制到芯针线上,在电弧管的情况下被模制到放电室。 然后将该部件模制在蜡芯上,以提供整体形成的具有由蜡芯限定的适当尺寸的空隙体积的一体式部件。 在零件在蜡芯周围硬化之后,通过常规方法去除芯。 可以在穿过芯针线之后留下的成品模制件中的孔被填充,或者在电弧管的情况下,它们可用作通道以适应电极。
