Thesis: Multi-Class Classification for Quality Control in Low Pressure Coating Processes

The Position

We are a spin-off of RWTH Aachen University, which develops a special coating technology to enable recyclable plastic packaging for various applications. We are offering a thesis in the field of quality control to help build a knowledge base that will significantly advance the circular economy for plastics in Germany and the world.

Plastic packaging plays an essential role in our daily lives by storing and protecting products and extending their shelf life. It is crucial to demonstrate that our coating meets the quality standards required for packaging that comes into contact with food, cosmetics, or highly reactive substances. Currently, this is assessed using binary classification. To better monitor the process and identify the causes of insufficiently coated packaging, we aim to research the application of multi-class classification strategies. Your thesis will have a real impact on our work. The scope can be adapted for a bachelor's or master's thesis.
