Simulating Warpage in Thin-Walled Plastic Parts

Hey everyone,
I’ve been working on some custom plastic fabrication projects that involve thin-walled parts molded through injection. One recurring issue we run into is post-molding warpage, especially in flat or complex geometries.

Has anyone used SimScale to simulate and predict warping or dimensional instability in plastic components?

  • What simulation setups or boundary conditions gave you the most accurate results?
  • Any tips for improving mesh quality or material settings when working with polypropylene or ABS?

Would love to hear how others are using SimScale for fabrication-related simulations like this. Thanks in advance!

Hey @charlenesays ,

Did you explore our public projects page yet? You should be able to search for relevant projects there by using keywords as search terms. You can then also make a copy of these projects and play around with the models.

From a simulation perspective, you should be able to achieve different kind of results for different input / setups depending on what exactly you want to study in the entire process. Feel free to explore some simulation types in our tutorials section to decide which analyses you would like to use and for what exact use case.

Here are some general mesh quality tips: Mesh Quality | Mesh Visualization Tips | SimScale

Feel free to get back to us with a project link or a more specific question on your setup once you know your simulation requirements in more detail.

Best,
Satvik :slight_smile:
