The data was collected during the research project 'ProBayes' conducted by SKZ (German Plastics Center) and Fraunhofer IPA from 2021 to 2023. This dataset was recorded in November 2022 and represents a Design of Experiment following a D-opimal pattern.
An injection moulding machine (KraussMaffei 160-750PX) was equipped with peripheral devices and quality control devices, as you can see in the following figure. The part manufactured with the injection molding machine is called 'warpage shell' (~ Verzugsschale). It is used because it allows to easily reproduce warpage and shows very well the effect of different temperatures on the geometry. It was produced with polypropylene (Borealis HE125MO). The data from all different data sources were combined into one PARQUET file, where each row holds the data of one part / cycle. Each part can be identified using the unique MachineCycleID.
Hard facts:
- 303 injection moulded parts (28 experimental points)
- 9 datasources
- 396 features per part / injection molding cycle
Check out the data_description.pdf for additional information.
A Design of Experiment (DoE) with a d-optimal pattern was conducted varying the following four parameters:
- Cylinder Temperature
- Mold Temperature
- Injection Speed
- Holding Pressure
All produced parts were manually inspected and classified into OK / NOK and some other labels, which you will find in the data_description.pdf
Project 21815N of the research association „Fördergemeinschaft für das Süddeutsche Kunststoff-Zentrum e. V.“ and the "Fraunhofer IPA" was funded by the Federal Ministry for Economic Affairs and Climate Action (BMWK) via the Federation of Industrial Research Associations (AiF) within the framework of the programme for the promotion of joint industrial research on the basis of a resolution of the German Bundestag. The authors would like to thank the funding body for providing the financial resources and all the members of the project-accompanying committee for their active cooperation in the research project.
