Gate Vestiges on Silicone Sealing Faces: Location and Trimming

Molding, Tooling and Finishing
Key point: Review gate locations against sealing, touch and appearance zones. A remnant acceptable on a nonworking face is not automatically acceptable on a contact surface.

Scope and common interpretation errors

For injection- or transfer-molded parts, without one gate geometry for every product.

Gate position affects filling and removal. Cutting can leave protrusions or recessed damage; 'no flash' alone does not define gate-zone function.

Turn the review into recorded checks

StepAction and evidence
1 · Mark restricted zonesIdentify seal bands, grip surfaces, thin moving regions and critical appearance faces.
2 · Review manufacturing optionsCompare gate location with filling, demolding and finishing.
3 · Agree limit samplesValidate contact and appearance with different vestige shapes, not only protrusion height.

A comparison to avoid misinterpretation

Moving a gate away from a seal may create incomplete fill elsewhere. Balance the filling design rather than treating position in isolation.

Frequently asked question

Does cutting flush remove every risk?

Recessed cuts and local damage still need inspection.
