Constant profiles specify operating parameters, such as pressure or flow rate, which have a constant value through a step.
Profiling operating parameters can provide greater control over the final product. Factors such as warpage can be reduced by profiling the packing pressure over time. Profiles within the Autodesk Simulation Moldflow product are used to simulate these adjustments.
Constant profiles can have a stepped value incorporated. Profiles are defined in the Process Setting Wizard by a table outlining how the parameter is to change through the cycle. If a Packing pressure vs time profile is specified with the values in the following table, a profile that looks like the following diagram will result.
| Time | Packing pressure |
|---|---|
| 0 | 150 |
| 5 | 150 |
| 5 | 125 |
| 10 | 125 |
| 10 | 100 |
In this example, the time value is duplicated to achieve the vertical step, and the packing pressure value is duplicated to achieve the horizontal step.
