Scope and common interpretation errors
For tooling-process reviews by qualified personnel; no universal vent dimensions are supplied.
Blocked venting and excessive local gaps may coexist. Dirt and clamp condition also matter; enlarging every vent can spread a local problem.
Turn the review into recorded checks
| Step | Action and evidence |
|---|---|
| 1 · Map defects | Mark bubbles, incomplete fill and flash by cavity and orientation. |
| 2 · Review maintenance first | Check blocked channels, parting-surface damage and tool installation. |
| 3 · Run one controlled change | After review, adjust individually and record stability and trimming effort against the original state. |
A comparison to avoid misinterpretation
Bubbles only at the flow end with flash elsewhere call for local airflow analysis, not a simultaneous all-round vent change.
Frequently asked question
Does more venting guarantee no bubbles?
Raw material, filling and cure conditions still need checks.
