Case Study: The LEGO Group achieves faster, more accurate injection molding simulation with ANSA by Cadence

The LEGO Group cuts mesh generation from 1–4 hours to 5 minutes with Cadence

The LEGO Group faced a challenge in simulating its plastic injection molding process, specifically in automating the mesh generation for runner systems to accurately analyze phenomena like shear heating. This manual process was time-consuming. To address this, The LEGO Group worked with Cadence Design Systems, utilizing its ANSA software to automate the workflow for Moldex3D simulations.

Cadence's solution involved using ANSA's unstructured solid-mesh generation to automatically create high-quality meshes with thick prism layers, which are crucial for capturing shear heating effects. This fully automated process drastically reduced mesh preparation time from 1-4 hours down to just 5 minutes. The result was a stable, repeatable, and reliable workflow for Cadence's customer that improved simulation accuracy.
