🎓Development of a robust optimisation process for the structural optimisation of blow-moulded plastic hollow bodies, taking into account material quality losses due to an increased proportion of recycled material

Plastic products are widely used in many industries and can be manufactured particularly cost-effectively using extrusion blow moulding. However, this results in process-related variations in wall thickness, which are exacerbated by uncertainties in the manufacturing process and in the material properties - especially when using recycled materials. In order to develop efficient and resource-saving products, both the geometry and the wall thickness distribution must be optimised. The aim of the doctoral project is to develop a product that is as light and robust as possible and that functions reliably despite variations in wall thickness.
