Under the pressure of the injection process, the core half of the mold can be deflected. This will result in thickness variation of the part, and is a frequent problem with long, slender product such as vials, test tubes and pen barrels..
The Core shift simulation provides detailed information about the movement of the mold core and its interaction with the polymer flow process as the plastic is being injected.
The Core Shift tab provides an opportunity to decide whether or not to run an core shift analysis. If selected, you can set the frequency of core shift analysis, the matrix solver used and the accuracy of the calculation.
