Mold-melt temperature difference (top), part result

The Mold-melt temperature difference (top), part result is generated at the end of a Cool analysis.

It shows the difference in temperature between the part side and mold side of the part/mold interface on the top side of the part. The top side is defined by the orientation of the mesh elements.

The difference in temperature is determined by the Mold-melt Heat Transfer Coefficients (HTC) values.

Tip: The HTC values are set in the Mesh tab of the advanced options of the Process Settings.

A lower HTC value represents a greater resistance to heat transfer between the polymer and the mold.

Things to look for

Uneven part temperatures may result in warpage as the part cools after ejection. This may be because the mold surface is not conducting sufficient heat during molding.

To compensate for low mold conductivity, it may be necessary to add or alter cooling circuits to draw the extra heat away.
