CAE simulation is now a common practice in product design/examination.
Some customers refuse to create a mold if the CAE results are not promising, which makes us realize how important this process is.
However, the results obtained from CAE may differ from the results desired by the designer.
For example, if a designer wants to evaluate the deformation of a product by warp analysis
The figure above is a contour plot of the results of the sled analysis as viewed from the overall coordinate system. The area with the largest warp deformation is shown in red. In this contour diagram, the area around B does not appear to be so deformed.
On the other hand, below is a contour diagram of the fastening hole at A, aligned with the reference plane.
Even though the shape of the product has not changed, there is a big difference in the contour map near B.
This means that the "apparent" deformation of the product changes depending on where the reference point for the deformed product is set.
Resin products are often used in assemblies, and depending on the amount of deformation, there is a possibility that even if the first part A can be fastened to the mating part, the second part cannot.
In other words, it is difficult to obtain the results we want to know unless we evaluate the results obtained by CAE with a reference plane that matches the design concept.
We have been evaluating CAE results by setting up a reference plane in every possible way.
As a result, we have accumulated a great deal of knowledge and know-how to a level that can be used in mold making.
