Scope and common interpretation errors
For shaped static frame seals. Review radii against the actual design; no universal minimum is specified.
Frame length, corner radii and section shape control material distribution. Overall outline checks can miss mismatched inner and outer radii or concentrated installation stretch.

Turn the review into recorded checks
| Step | Action and evidence |
|---|---|
| 1 · Overlay the geometry | Compare free-frame and gland sections and plan views. |
| 2 · Review insertion order | Compare locating all four corners first with pulling the frame along each side. Record local rolling. |
| 3 · Validate limiting states | Inspect closure marks and corner leakage. Distinguish outline-length changes from cross-section changes. |
A comparison to avoid misinterpretation
If straight sections look even but corners bulge, photograph the open assembly and check whether stretching the sides has pushed surplus material into corners before changing hardness.

Frequently asked question
Can cutting and regluing the frame solve the problem?
It introduces a joint that requires a new structural and joint-reliability assessment.
