The Temperature result shows the plastic temperature at a specified time, over all laminates through the part thickness.
This is a profiled time-series result which can be specified at constant intervals or at certain times.
Note: For compression-type molding processes, this result is plotted displayed on the deformed mesh as the default setting. With this default setting, if you click through the time steps you can watch the polymer as it is compressed into the part shape. To turn it off, so that all you see is the result on the part, right-click the result, select Properties and uncheck Display on deformed mesh.
Using this result
The Temperature display shows the plastic temperature results through the part thickness at a specified time.
Note: The plastic temperature at the mold-melt interface may differ from the specified mold surface temperature due to the heat transfer coefficient (HTC) settings.
If the flow front temperature is too low in a thin area of the part, hesitation or short shot may occur. In areas where the flow front temperature is too high, material degradation and surface defects may occur.
Make sure the flow front temperature is always within the recommended temperature range for the polymer you are using.
Tip:
- Keep the cooling and packing pressure distribution as uniform as possible to minimize warpage.
- Injection profiles may be required to obtain satisfactory temperature distribution.
Things to look for
- Hot spots, indicating excess shear heating usually around the last place to fill and around the gate. Try to acheive more uniform cooling.
- Cold spots, indicating hesitation.
- Excessive shear heating or cooling.
