Temperature, part result

The Temperature, part result shows the average temperature at the part boundary, which is at the part side of the part/mold interface, over the duration of the cycle.

This temperature is determined using the Mold-melt Heat Transfer Coefficients (HTC) values .

Tip: This is set in the advanced options of the Process Settings.

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

Using this result

Use this result to find localized hot or cold spots, and determine whether they will affect cycle time and part warpage. If there are hot or cool spots, you may need to adjust the cooling channels.

The difference between the temperature across the top or bottom face of the part and the target mold temperature should not be greater than ±10°C.

The temperature variation over each mold face should be within 10°C. The Temperature, part (top) result should not be more than 10–20°C above the inlet temperature.

The wall temperature can be investigated by selecting (Results tab > Properties panel > Plot Properties) when the result is displayed, selecting the Scaling tab, and scaling the Max box to a smaller value.

For 3D models, use a cutting plane to investigate hot or cold spots inside the part.

Note: If you animate the result, it will show you how the temperature changed over the duration of the analysis inside the solid model.

Things to look for

When viewing the Temperature, part result, watch for the following.

• Regions that freeze off early. The gate should not freeze before the part.
• Hot and cold regions.
• The cooling pattern. Is it evenly distributed?
