The Runner Balance Analysis is used to determine the optimum volume for the sections of the runner system. This analysis ensures that the part fills evenly and there is an acceptable pressure magnitude in the cavity, minimizing runner volume.
The Runner Balance analysis is supported for the following analysis technologies:
Runner systems should be balanced to reduce overpacking during the filling phase. During a Runner Balance analysis, the runner system dimensions are altered to ensure that parts fill simultaneously and the volume of the feed system is minimized.
A well-balanced runner system can make considerable savings in material usage. Before performing a Runner Balance analysis, you should check the Fill analysis and ensure that you are satisfied with each of the following:
The Runner Balance analysis is for a model with an attached runner system. A runner system that is added after a Fill+Pack analysis helps you balance the cavities. The aim is to achieve runner dimensions with the following characteristics:
The Runner Balance analysis is used to determine the optimum volume for the sections of the runner system.
Runner balance constraints are an optional analysis input that you can set for a Runner Balance analysis.
Runner balancing is performed as a conditional minimization of a criterion function, which is calculated by using the results of a simplified analysis.
