Creating a rapid heating and cooling inlet

Make sure you have modeled cooling channels, set the Analysis Sequence to include a Cool (FEM) analysis, and have selected a transient solver from the Mold temperature options in the Process Settings Wizard.

Note: For the first injection molding cycle, injection occurs at time t=0, while the mold is closed. At t=0, therefore, no rapid mold heating will have occurred. Following cooling, the mold opens for part ejection, and at the same time the secondary air purge occurs to remove residual coolant. Only at this time does the first rapid mold heating occur, followed by the start of the second injection molding cycle. The second injection cycle, therefore, is the first cycle in which the entire mold heating and cooling cycle will have occurred.
  1. Click Boundary conditions (Home tab > Molding Process Setup panel > Boundary Conditions) to open the Boundary Conditions tab.
  2. Click on the drop-down menu associated with Coolant inlets (Boundary Conditions tab > Cooling panel > Coolant inlets) to view the options.
  3. Click Rapid heating and cooling Rapid Heating and Cooling Inlets.
  4. Click Edit to open the default Rapid Heating and Cooling inlet dialog.
  5. Define whether you would like temperature or time control, and the duration of the air purges which remove the heating fluid or coolant prior to filling with the subsequent solution. The secondary air purge occurs first, at mold open time, to remove coolant prior to heating.
  6. Save the edits with a new name that reflect the changes, then click OK to close the dialog.
