How to speed up the Gating Iteration by 95%

摘要

WELD line issue is a common surface defect of plastic products. It is not just an aesthetic issue but can also affect the structural properties. Other than part design, gate location design is another major factor of weld lines. Take automotive products as an example; they are large thin-shell parts with large L/t ratio, and the gate design mainly dictates the resulting product quality. To simulate the molding process of this automotive part, users traditionally have to set the gate locations based on their experience at the pre-processing stage, and then run filling analysis. The calculation time can be more than 3 hours because the mesh element amount is considerably large for big parts. When the analysis is done, users have to check if the weld line positions are acceptable.
