Hot tracks! Shaping the future of extrusion through thermal agility

Bachelor- or Master thesis

The aim of your work is to develop and validate a heat transfer model for thermally agile extrusion tools

In film extrusion, thermal set-up times, i.e. the time required for extrusion tools to heat up or cool down, represent a major bottleneck in reducing downtimes in production. The optimization of the tool mass, on which this parameter is directly dependent, is therefore of great importance.

Simulations can help optimize the heating time of large extrusion tools.

The work is related to this research project:

In a new research project, different lightweight construction strategies are to be used to reduce the tool mass and thus the thermal set-up time. By using simulations, not only the mechanical strength, but also the heat transfer in the mold should be considered. To reduce the computational complexity, a special modeling approach is pursued that considers the Mould and the flow channel of the melt in a single computational grid.

Objective:

The aim of your work is the implementation of a heat transfer model of a new simulation environment in the open source software OpenFOAM. The model will then be simulatively validated for different film tool geometries.

Your task:

Implementation of a heat transfer model Implementation of a heat transfer model
Carrying out simulations for different film tools Carrying out simulations for different film tools
Integration of the heat transfer model with a simulation model to calculate the tool deflection

Your profile:

  • Technical or scientific studies (mechanical engineering, CES, industrial engineering with specialization in mechanical engineering,…)
  • Basic knowledge of an object-oriented programming language (e.g. C++)
  • Interest in application-oriented simulations
  • Basic knowledge of construction desirable
