Experimental and computational analysis of the heating step during thermoforming of thermoplastics KU Leuven
The present study addresses the difficulties in heating thermoplastic sheets for thermoforming applications. In industrial environments, the sheets are heated in a contact free method by means of convective hot air ovens and infrared radiation. In this study the temperature evolution at the outer surface as well as the core of thermoplastic sheets as a function of time is measured by means of thermocouples. These measurements reveal significant ...
