The Flow analysis module predicts how
molten plastic
material fills a cavity. It accounts for heat transfer between the
material and mold during filling, and predicts the changes to viscosity as the material
begins to solidify.
Results from a Flow analysis include:
- Distributions of pressure and temperature within the cavity
- Detection of potential short shots, weld lines, and air
traps
- Evaluation of melt front temperature to gauge the severity of
weld lines
- Comparison between the shear load and the critical value of the
material
- Fiber orientation analysis of filled materials
By default, the software specifies the Flow process parameters automatically.
You can also control how the machine injects material into the cavity by specifying
either a filling time, an injection flow rate, or a
flow
rate profile in the Fill
Settings PropertyManager.
