The Effect of Ultrasonic Oscillation on the Quality of 3D Shapes During Deep-Drawing of Paperboard

Albrecht Löwe, Marek Hauptmann, Jens-Peter Majschak

Abstract


In this publication, the ultrasonic-assisted deep-drawing of fiber-based materials, whose implementation was presented in Löwe et al. (2016), was studied in detail. Methods were developed for measuring the properties of deep-drawn cups, including cup stability, shape deviation, and surface quality. The relationship between these properties and the process parameters were determined with a design of experiment, which allows the user to adjust the cup properties in order to optimize them.
