The Temperature result shows the temperature of the polymer at nodes, at specified times during the analysis. This result is generated by a Fill analysis using 3D analysis technology, and may be refined by a subsequent Pack analysis.
The Temperature display shows the plastic temperature results through the part thickness at a specified time. The plastic temperature at the mold-melt interface is the mold surface side of the interface due to the heat transfer coefficient (HTC) being used in the temperature calculations.
Using this result
The
Temperature result can be used in many ways:
- Use a cutting plane to view the temperature gradient through the thickness.
- Animate the result to view the temperature variations over time.
- Use a single contour set at the transition temperature to determine when the gate has frozen.
- Use a single contour set at the ejection temperature to identify the areas that freeze last. These areas control the cycle time.
- Plot the temperature as a Probe XY plot to se a 2D graph of the temperature through the cross section.
Note: To increase the freeze time resolution, increase the number of intermediate files requested during the packing phase.
Thermoplastic 3D Overmolding
The mold and melt temperatures used in the overmolding component are initialized by the temperatures at the end of the first component stage. Therefore, the Temperature result shows the temperatures on the first component (first cavity), as well as the temperatures on the overmolding component (second cavity). This allows you to see the effect of the overmolding filling stage on the first cavity.
Things to look for
- Areas that freeze early, preventing the part from being adequately packed.
- Check when the gate has frozen, using a single contour, and noting where the contours seperate.
- Hot spots, indicating excess shear heating usually around the last place to fill and around the gate.
- Check mold cooling rates, and see whether there are hot or cold spots within the mold.
- Cold spots, indicating hesitation.
