 Introduction to the Adviser

Cavity models

The Adviser allows you to create a model of your part in a CAD package, and then read the model in to the Adviser.

Preparations

For a Plastic Filling analysis, you need to select the polymer and the injection location. Other settings, such as material temperature and pressure, are automatically selected according to the material's properties, but you can alter them if you wish.

Additional analyses can also be performed in order to investigate other aspects of part design.

Results

After the Plastic Filling analysis has finished, you can look at the Confidence of Fill result, which is derived from the Fill Time, Injection Pressure, Pressure Drop and Flow Front Temperature results.

A green area has a high confidence rating, yellow indicates a medium confidence rating, while red shows a low confidence rating.

Read the Confidence of Fill advice for suggestions on improving a medium or low result. If the Confidence of Fill result indicates problems, look at the other results to find the reason for the low or medium confidence of fill.

If the Confidence of Fill result shows any molding problems, look at the pressure and temperature results to identify where the problem is coming from. After looking at the Confidence of Fill, you should study the air trap and weld line results to find other possible molding problems.

You can then review the inputs and try to resolve any problems. Areas on the part that show low or medium confidence of fill may need to be redesigned or a new material selected for the part to fill.

Once you are confident that the part will fill, you can check the Quality Prediction result, which estimates the expected quality of the part's appearance. To find out more information and possible solutions to any implied problems, use the same methods you used for investigating the Confidence of Fill result. You can also use other analyses available to investigate and solve design problems.

Further Analysis

If your model needs more detailed analysis, you can save it in .sdy format, which can be analyzed by products in Moldflow Plastics Insight, such as MPI/Flow or MPI/Cool. These analyses provide more detailed information about how the part fills.
