The Gas time result shows the position of the gas flow front at regular intervals over the gas injection phase as the cavity is filling with polymer.
The Gas time result is measured from the start of the cycle, at which the gas reached a particular element in the part.
This result is generated from a Midplane or 3D Gas-assisted Fill+Pack analysis.
Using this result
Each color contour represents the parts of the mold which were being filled at the same time.
Use the Gas time result to check how the compressed gas has filled the part, and which sections that the gas has penetrated. This result is equivalent to the fill time result for the polymer.
Note: In the case of Gas-assisted Fill+Pack analysis using 3D analysis technology, the Gas time result display may not give a true representation of the size of the gas core. This is because only those elements where all four nodes are filled with gas are included in the gas time result display. For a true representation of the gas core, see the Gas core result.
Things to look for
- Check that the gas has not penetrated to unwanted areas of the part.
- Check "when" the gas is penetrating. If it is penetrating too fast, you may need to vary the gas injection pressure and/or time.
