There are some technical defects induced by the process of glass molding press (GMP) of micro optical glass components, which generate worse shape precsion, worse surface quality and worse optical properties. The new ultra-precision thermal molding press of micro optical glass components with assistance of ultrasonic vibration is proposed. By adding ultrasonic vibration to mold during GPM process,the flow chacacteristics of molten glass will be improved, the shape and surface morphology of mold will be precisely copied to micro optical glass components.The key scientific issues such as the effect of ultrasonic vibration on flow characteristic of molten glass, size and shape effect of transferability,the forming precision of shape of mold, as well as the process numerical simulation will be studied in this project in order to reveal the forming mechanism of mirco optical glass components during GMP process with assistance of ultrasonic vibration, and develop new method and technology for mass production of mirco optical glass components.
