The Mold-melt temperature difference result is generated at the end of a Cool analysis for a 3D part.
It shows the difference in temperature between the boundary of the part and the mold. This may be significant if there is an air gap between the part and the mold.
NoteThis result requires that you set each element to use in the part surface properties.
Things to look for
To compensate for low mold conductivity, it may be necessary to add or alter cooling circuits to draw the extra heat away.
Adjustments such as those above can only be made using a licensed Autodesk Simulation Moldflow Adviser or Autodesk Simulation Moldflow Insight
