Examination of Overflow position

Repeat "Design --> Simulation -> Design Change" process in order to find the optimum desgining by taking advantage of one of ADSTEFAN features, "High speed analysis." In this case, Fluid flow analysis is conducted on the initial designing due to find optimum overflow positions. From the simulation results, parts filled in last with reminding air are confirmed.

Evaluation of the simulation result : Situation of the reminding air when injection is completed. (Blue shows the reminding air) * At least 4 overflows (shown in red arrow) are required. Filling is not adequate at the left side.	Evaluation of the simulation result : Situation of the reminding air when injection is completed. (Blue shows the reminding air) * Overflows are still required at the same positions but filling at the left side is improved.
