Sustainability in Direct Compounding: Enhancing Recyclate Performance During Processing

Call for Application: Bachelor’s Thesis or Master’s Thesis

As part of this thesis, you will investigate the influence of various process parameters and machine configurations on the resulting properties of recyclates. This work contributes to the optimization of a new Direct Compounding and Injection Molding (DCIM) system and its market viability.

Topic of the Thesis:

Recycling is an indispensable part of a circular economy. In this context, technical molded parts, among other things, must be fed into a recycling process. However, (repeated) recycling leads to cumulative damage to the material, as a result of which the properties of the recyclates decrease significantly with an increasing number of recycling cycles. A promising approach to minimizing degradation is the DCIM process, which combines compounding and injection moulding in one process. A major advantage of this process is that, in contrast to conventional processing, the material is only melted once. The resulting reduction in thermal and mechanical stress generally leads to less damage to the material, which in turn has a positive effect on its properties.
