Use the Vents tool to create an exit for air to escape as the fluid advances.

Location: Molding tab, Tooling secondary ribbon

Venting allows air to escape so that the plastic can fill the molding cavity. If the air is not evacuated, the cavity will not properly fill, resulting in defects such as short shots, burning, voids, or dimensional variation.

Vents are typically machined on the parting lines, where the end of the fill reaches the edge of the mold.
