Poster 9-10 - Improving Thermoform Quality using a novel Heating Technology in combination with simulation based Optimization

摘要

Sascha Bach: watttron GmbH, Freital, Germany Novel matrix heating technology allows defined inhomogeneous heating of sheets for thermoforming Specific blister could not be produced with conventional female forming process due to wrinkles and poor wall thickness distribution With the aid of simulation based optimization an appropriate temperature profile for improved forming quality could be predicted The temperature profile (applied by the novel matrix heating system) leads to significantly improved wall thickness and prevents from wrinkles Thermoforming with novel matrix heating equipment enables material saving of approx. 25% for the exemplary blister design
