Ultrasonic Vibration-Assisted Hot Glass Embossing Process

Abstract

This chapter is intended to provide the reader with background information about the assistance of ultrasonic vibration in hot glass embossing process. For this purpose, the description of the conventional hot glass embossing process and the ultrasonic vibration-assisted hot glass embossing process will be defined first. Based on the comparison between these two processes, components of the ultrasonic vibration device which produces ultrasonic vibration will be discussed in principle. Among these components, ultrasonic horn will be especially analyzed. After that, each interesting effect of ultrasonic vibration on hot glass embossing process will be explained in detail. With the development and application of simulation tools on forming process, this chapter will finally describe some results of finite element analysis (FEA) of ultrasonic vibration-assisted hot glass embossing process.
