Categorize your mold components to allow the solver to identify them. You will then
define their materials.
You will categorize the mold components into two mold
groups, one for the mold cavity and one for the mold core. This allows you to view the
results of each mold group separately.
-
In the display window, select the mold cavity.
-
In the Mold Group 1 card, click add
to assign the cavity as a part of the mold group 1.
Click expand

to view the list of added components for
verification. If necessary, you can click remove

to remove a categorized component from the mold
group.
-
In the Mold Group 1 card, click hide
to hide the categorized component to verify that
your components are correctly categorized.
-
Repeat steps 2 and 3 to select the sprue bushing and add it as a part of
Mold Group 1.
-
In the display window, select the mold core.
-
In the Mold Group 2 card, click add
to assign the core as a part of the mold group 2.
-
In the Mold Group 2 card, click hide
to hide the categorized component.
-
Repeat steps 6 and 7 to select the ejector pins and add them as a part of the
Mold Group 2.
You must categorize all components in contact with the plastic part into one
of the mold groups to ensure accurate temperature results. Excluding them
from the analysis creates additional sources of cooling that distorts the
temperature results and the cooling time estimation.
-
In each Mold Group card, make sure P20 Mold
Steel is selected from the Select
Material list as the mold material.
