Scope and common interpretation errors
For multistage dimensional control, without implying every silicone part needs post-curing.
Treatment, support and cooling can change shape, especially in soft long parts. An upstream pass does not establish finished-part conformity.
Turn the review into recorded checks
| Step | Action and evidence |
|---|---|
| 1 · Define acceptance state | State completion of post-treatment, washing and specified conditioning. |
| 2 · Track matched specimens | Record before-and-after dimensions and positions on identified specimens without mixing cavities. |
| 3 · Classify the change | Separate overall scale, local warpage and measurement effects before changing tooling or support. |
A comparison to avoid misinterpretation
A bent long edge with stable hole spacing calls for support and restraint checks before enlarging the mold by an overall shrinkage ratio.
Frequently asked question
Must an oversized upstream part always be scrapped?
Judge against the final state and approved process controls; do not relax limits informally.
