How do I check for Gate Freeze on a 3D meshed part in Moldflow?

Checking for Gate Freeze on a 3D mesh using Temperature and Part Weight plots

How can I tell when gate freeze occurs in my Fill-Pack analysis?

Modifying the default Temperature plot is an excellent way to check for gate freeze.

Validating this result with the Total part weight: XY Plot will help confirm the gate freeze time.

Both methods are described below.

This video will walk you through the following steps

Using the Temperature Plot:

Right-click on your material in the Study Task Pane
Choose Details
Click on the Rheological Properties tabNote the Transition Temperature (The temperature where the molten polymer solidifies)
Click on the Temperature plot to display it
Right-click on the plot and choose Properties
On the methods tab, choose Contour (Shaded is the default)
Place a checkmark in the Single Contour box
Set the Contour value to the transition temperature of your material
Click Apply
Go to the results tab, and step through the animation

As you step through the animation, the material will disappear and disconnect from the gate

Note the time stamp that this disconnect occurs

This is the time of gate freeze (no more material will enter into the cavity)

Using Total Part Weight: XY Plot

On the Results tab
Click on New Plot, then Plots
Scroll through the available results to find the Total part weight: XY Plot
Click OK
Click in the graphics window and choose Examine
Click on the small black diamonds to find when the part weight normalizes, and note the time
This should match closely with the gate freeze time

Compare the time that part weight stabilizes and gate freeze occurs to help establish your packing time.
