Air eject should break the seal and assist release without reshaping the part. Excessive pressure, large local ports, early application, or poor vent distribution can balloon broad panels, dent thin walls, or create whitening around restricted features.
The part should be observed at the first moment of release. Distortion that begins before separation indicates pressure is acting while the polymer is still constrained or too soft. A sharp local mark points to concentrated airflow; global movement points to excessive pressure or unsupported geometry.
Eject pressure, rise rate, timing, and port distribution should be reduced to the minimum that gives repeatable separation. Mechanical stripping, draft, undercuts, cooling, and vacuum release must be corrected first. Air eject should not be used to force a locked part from the mold.
