Bachelor thesis or Master thesis
The aim of this work is the development of an energy-efficient inline drying system as well as the investigation of the effects of thermal stress on material properties.
© IKVTopic of the thesis:
Drying hygroscopic plastics such as polyamide or PET is a critical step in ensuring the processing quality and mechanical properties of components. Conventional air drying systems often dry the entire material, which can lead to unnecessary thermal stress and potential ageing of the material. In addition, this process is often energy-intensive. Inline drying systems with infrared halogen emitters offer the possibility of drying the material in a targeted manner before processing, treating only the required quantity and thus increasing energy efficiency and minimizing material stress.
Objective
- Development of an energy-efficient inline drying system with IR halogen radiators.
- Investigation of the mechanical and thermal material properties after different drying processes.
- Analysis of the energy efficiency of the system compared to conventional air drying.
- Evaluation of the effects of moisture absorption and thermal stress on workability and component quality
