摘要： A method of manufacturing a pressed lens based upon the discovery that a high quality lens may be molded despite the fact that the lens is cooled without pressure being applied to the mold. A lens preform is inserted into the pressing mold and pressure is applied to the mold while the preform and mold are at a temperature corresponding to a viscosity of the preform of 10.sup.8.5 -10.sup.10.5 poise. The pressure is then removed while the resulting molding remains in contact with the mold and the preform and mold are then cooled. When the temperature of the preform has fallen to a value corresponding to a viscosity of the molding of not smaller than 10.sup.11.5, the molding may be removed from the pressing mold. The preform may be inserted into the mold and then the preform and the mold may be heated prior to pressing, or alternately, the preform and the mold may be heated separately and the preform may be transferred into the mold for pressing. In the latter case, the preform is held by a holder which remains in the mold during pressing. To increase the lens production rate, the lens and the mold may be cooled at a location different from the location at which pressing occurred.
摘要翻译：基于发现高品质透镜可以被模制的制造压制透镜的方法，尽管透镜被冷却而没有压力施加到模具。透镜预成型件插入压制模具中，并且压力施加到模具，同时预成型件和模具处于与预成型件的粘度为108.5-1010.5泊的温度相对应。然后在将所得模制品保持与模具接触的同时去除压力，然后冷却预成型件和模具。当预成型体的温度下降到与模制品的粘度相当的值不小于1011.5时，可以将模制品从压制模具中取出。预成型件可以插入模具中，然后预压件和模具可以在压制之前被加热，或者可选择地，预成型件和模具可以单独加热，并且预成型件可以被转移到模具中用于压制。在后一种情况下，预成型件由在压制期间保留在模具中的保持器保持。为了增加透镜的生产速度，透镜和模具可以在与发生压力的位置不同的位置被冷却。
