The Co-injection molding analysis can incorporate hot runners. Because the hot runners are occupied by one material during molding, you need to specify which material (A or B) is injected from a particular injection location.
Note: This is used only when you want to include hot runners in a Co-injection molding analysis, and when there are two injection locations with each location injecting different materials.
Ensure that you have modeled your part, including the hot runners.
Ensure that you have set the injection locations.
Click (Boundary Conditions tab > Feed System panel > Set Controller). The Set Material to inject (A/B) dialog appears and the cursor changes to cross-hairs.
Click New, select A in the Material to inject (A/B) drop-down list, enter a name for the property and click OK.
Click the cross-hairs on the hot runner, hot sprue or hot gate element where material A is to be injected.
Repeat steps 4-5 to create a Material to inject property for material B, and assign that property to required location in the model.
Right-click the mouse and select Finish Set Co-Injection Material.
