摘要：
An ultrasonic-assisted injection molding system and method for making precisely- shaped articles. A source of ultrasonic energy is positioned to apply vibrational energy to a mold cavity connected to at least one gate in flow communication with a source of molten (co)polymer. The mold is heated to a temperature of 104-116°C, and the molten (co)polymer is injected into the mold cavity. After cooling the mold until the molten (co)polymer within the gate has solidified, ultrasonic energy is applied to the mold without remelting the solidified (co)polymer within the gate until the temperature increases to 116-122°C, thereby substantially relieving flow induced stresses. The mold is then cooled until the temperature decreases to 101-107°C, and is thereafter heated until the temperature increases to 116-122°C, thereby substantially relieving any thermally induced stresses. The mold is cooled until the molten (co)polymer has solidified, thereby forming a precision molded plastic optical element.
摘要（中）：
一种超声波辅助注射成型系统及其制造方法。 定位超声波能源，以将振动能施加到与熔融（共）聚合物源流动连通的至少一个门的模腔中。 将模具加热到104-116℃的温度，并将熔融的（共）聚合物注入模腔中。 在模具冷却之后，门内的熔融（共）聚合物已经固化，超声波能量被施加到模具上，而不使固化的（共）聚合物在浇口内重熔，直到温度升至116-122℃，从而基本上减轻流动 诱发应力。 然后将模具冷却直到温度降至101-107℃，然后加热直到温度升至116-122℃，从而基本上减轻任何热诱导的应力。 将模具冷却直到熔融（共）聚合物固化，从而形成精密模塑塑料光学元件。
