Sigma Engineering aligns its booth concept with the motto “Sigmainteract — Autonomous Optimisation connects departments” and presents its new Sigmainteract.

In a cooperation project Sigma shows how to use virtual DoE during the entire development process of the project. With Sigmainteract results are displayed interactively and in 3D. Thus, its usage makes knowledge tangible and easy to share between departments.

Making informed decisions throughout a project requires involvement from partners in various departments. This means project data must be provided to each participant and they will need free and easy access to it. Therefore, Sigma presents its new Sigmainteract: Now, users can share Sigmasoft results interactively and in 3D with colleagues, project partners and customers. Sigmasoft hereby encourages the interdisciplinary exchange and provides a direct link between the simulation in development and production.

Visitors can experience and use Sigmainteract live at the booth. There, Sigma will demonstrate how virtual DoE is used most efficiently and how the Sigmainteract tool contributes to a good interdisciplinary exchange. As a demonstration Sigma uses the project ‘Pot Cloth’, which was realised as a collaborative project with Momentive Performance Materials GmbH, Germany, EMDE MouldTec GmbH, Germany, Wittmann Battenfeld GmbH, Austria, and Nexus Elastomer Systems GmbH, Austria.

In this project part design and tool construction were done in parallel. Therefore, it was necessary for all partners to work closely together. Simultaneously, Sigma conducted a virtual DoE for the validation of the part design and the evaluation of the heating concept.

The Sigmasoft results showed that the honeycomb structure of the part placed high requirements on the material and the tool. There was also a high possibility for air entrapments at the weldlines of the comb walls and premature curing during filling which would need to be prevented. With help from Sigmasoft the ideal length and power of the heating cartridges was determined to achieve an even temperature distribution.

Combining the results of these two DoEs, a common ground for all project partners was created and fast decision could be made.

Sigmasoft can be found in Hall 13, Booth B31.
