Process dependence of post-shrinkage

Bachelor’s Thesis or Master’s Thesis

The aim of this thesis is to investigate the process dependence of shrinkage in injection-molded components.

Process data from the injection molding machine will be combined in a model with shrinkage data obtained from tactile or optical measurements.

Topic of the Thesis:

In order to set up and control injection molding processes intelligently, the component properties of the molded parts produced must be determined promptly, ideally inline. However, the dimensional accuracy of the components can still change after removal from the injection molding process (known as post-shrinkage), meaning that the final component geometry cannot be directly deduced from the data measured inline. However, in order to be able to make statements about the expected post-shrinkage during demolding, the possibility of a data-driven replacement model is to be investigated.

The Thesis is written in this Working Group:

IKV focuses on the fusion of advanced algorithms, modeling and machine learning on the one hand and industry-oriented injection molding process engineering on the other. In the “Intelligent Production Systems” working group, we are investigating ways of predicting and controlling quality parameters in injection molding using data-driven models and algorithms. This is based on both simulative and experimental data.

Objective:

The aim of the work is to generate a database for assessing and modeling the influences of various machine and process variables on post-shrinkage.
