THE DEPENDENCE OF WALL THICKNESS ON CHANGES IN MATERIAL AND PROCESS CONDITIONS IN PLUG ASSIST THERMOFORMING

摘要

The European Commission, 6th Framework Program, Co-operative Research Project "Plug Materials Influence on Final Part Quality in the Thermoforming Process" with Project acronym "PlugIn" has as its goal to improve the understanding of plug assist thermoforming to increase productivity and competitiveness of the European thermoforming industry. This paper presents the PlugIn project work investigating the dependence of part wall thickness due to changes in plug-sheet material combination, plug geometry, plug velocity, plug depth and forming temperature.
