Injection Locations

Injection locations define where the plastic enters the part cavity. You must have at least one injection location.

This page discusses:

Plastic material at the specified melt temperature is introduced into the plastic part through injection locations. Each injection location is defined by a surface or a point.

Surface

For surface-based injection locations, the plastic enters the part from the entire surface you select.

If your model has a runner system, select the top of the sprue as your injection location.

Point

For point-based injection locations, the plastic enters the part at a location that you specify.

If your model does not have a surface that represents your injection location, specify any location on a surface as the center of a circular area through which the plastic is injected.

Note:

By not modeling the runner system, the effects on the plastic temperature and flow are ignored.

Typically, the diameter of the injection location should be 60-80% of the part thickness.

Automatic Creation of Injection Locations

If you created your part geometry in the Functional Plastic Parts app and created injection locations there, they will be used to create injection locations in the simulation automatically. You can delete these injection locations or add more injection locations, but these changes will not automatically propagate back to the Functional Plastic Parts app.
