Flow analysis predicts the flow of molten plastics material during the filling cycle and facilitates the understanding of filling characteristics of the part and thereby helps to validate the part design for producing good quality molded parts. Part design can be reviewed based on the results and suitably modified for improving the part quality.
Polymer selection
Flow analysis determines the behavior of polymer and its filling characteristics during the molding cycle and therefore helps to evaluate different polymers and select the most suitable one.
Optimization of feed system design
Feed system of the mold controls the distribution of material flow into the mold cavities. Flow analysis facilitates evaluation of alternate feed systems to achieve balanced filling.
Process Optimization
Flow analysis simulates the filling and packing phases of the molding cycle. Different process conditions can be evaluated and most appropriate process parameters can be chosen to produce the part.
For a set of process inputs (injection time, melt and mold temperature, pack profile etc) the following results can be seen:
* Injection pressure
* Clamp force
* Temperature reduction at flow front
* Weld line locations
* Air trap locations
* Volumetric shrinkage, etc.
Based on these results the most optimum process condition can be chosen
