The Air traps, including air vents result shows the locations where air traps are likely to occur, including specified venting analysis (air vent) locations.
This result is generated by a Fill or Fill+Pack analysis sequence for Thermoplastics Injection Molding, Thermoplastics Overmolding, Reactive Molding or Microchip Encapsulation molding processes using 3D analysis technology, when the option to Perform venting analysis is enabled.
You can control how this result is displayed by editing the plot properties.
Using this result
Use the Air traps, including air vents result to aid in selecting appropriate locations for air vents. If the specified venting analysis (air vent) locations coincide with predicted air trap locations, the specified locations are suitable to place air vents in the mold.
Tip: Use the Air traps result to identify preliminary areas for setting venting analysis locations. Then enable the option to perform venting analysis and run the analysis again.
Things to look for
To optimize the placement of air vents, try one of these options.
- Move the injection location(s) so that the air traps form in easy-to-vent areas.
- If no air trap is predicted near a specified venting analysis location, an air vent may not be needed at that location to remove trapped air from the mold.
- If an air trap is predicted near but does not coincide with a specified venting analysis location, move the venting analysis location to more closely match the location of the trapped air to be vented.
