Einflüsse auf die Oberflächenqualität von Organoblechbauteilen im Thermoformprozess (English shop)

Organosheet technology is characterised by a high lightweight design potential and, above all, efficient processing methods. However, surface defects occurring on the components during forming limit the possible fields of application. In order to avoid these defects, complex temperature control is required during the thermoforming process, whereby an adjustment of the semi-finished part and mould temperature is not possible in most cases. Thermally insulating mould coatings can be used to reduce the cooling of the organosheet responsible for the surface defects. These are intended to prevent the loss of temperature during thermoforming and thus lead to an increase in surface quality. In this context, the present contribution investigates the influence of the process parameters as well as of selected mould coatings on the surface quality of organosheet components, using the example of a forming process.
