The Flow rate, beams result shows the amount and rate of polymer that is delivered through runners into the mold cavity, allowing you to optimize the runner system design.
The Flow rate, beams result is calculated from the product of the average velocity and the cross-sectional area of the runner. This information is very useful for designing the runner system, especially when using a cavity with more than one gate. The inlet flow from the nozzle is distributed among all runner branches during filling. The flow distribution is dynamically adjusted, depending on the resistance from each branch.
For example, if the melt front of one branch reaches a thin section, the flow resistance increases so that the flow rate in that branch is dynamically reduced. At the same time, the flow rate in other branches must be increased to maintain the total mass balance.
From the plots of flow rate versus time at each runner branch, the amount of polymer that is actually delivered from that branch can be calculated. Runners that deliver an insignificant amount of polymer should be either re-sized or eliminated.
