One of the essential core elements of IANUS Simulation is the 3D CFD flow simulation for extrusion dies and screws.
Compared to costly experimental investigations, a 3D CFD flow simulation can be implemented quickly and allows a detailed insight into the process. In such a manner, a process can already be examined and optimized in the early stage of development.
Furthermore, the causes of the following errors can be identified quickly:
- Dead zones
- High dwell times
- Inefficient design
The advantage for the customer is an efficient product optimization. Black specks or tear-offs on the profile can be prevented from the start, additional costs for an unnecessary high waste of material can be avoided, and the energy efficiency can be improved in the best possible way.
The modern industry already uses flow simulations for several years. The 3D CFD simulations offered by IANUS Simulation do not only allow to optimize dies but also enable to design and configure screws optimally. Whether it is about a single- or a twin-screw, IANUS Simulation makes it possible to have a deep insight into the extruder, and it is well-known that an optimally designed screw allows for the optimal throughput as well as the optimal energy efficiency.
Furthermore, simulations make it possible to identify key figures, like the temperature peaks, the energy input or the shear distribution of the most diverse screws. Thereby, it is possible to determine easily both the optimal transition into the die, a comparison of the material stress and an optimal screw design respectively a configuration for the maximum throughput.
The specifically generated code Extrud3DPro is based on the 3D FEM (FeatFlow) code. That is why the CFD flow simulation can not only be depicted in 3D, but also at high resolution.
- No trial and error
- Quick calculations
- Easy handling without any initial training
- No additional personnel and material costs
- Low investment risk due to a high ROI and quick amortization
- Higher product and process quality
The aim of IANUS Simulation is to depict the customer’s process in the highest quality with simultaneous low costs.
“We often had difficulties with the die changes and had to try a lot to eventually avoid specks and tear-offs on the profile due to a poor die design. Together with IANUS Simulation we are able now to produce optimally in advance and without having to rework the dies.”
