Sink marks: packing evidence review

Separate the planned change from the measured response. Use the applicable process and inspection instructions; attach the individual results.

Job / trial identity

Date / part + revision / press / mold / active cavities / material + lot / trial and process-record references

Local feature and inspection

Sink location / sample + cavity IDs / inspection reference + method / time after molding / photo or measurement attachment

What changed?

Pressure, time, profile step, or multiple controls? Exact labels, before/after values + units in attached record / change time / other events

Requested setting / available actual results

Keep machine-side and cavity measurements labeled separately / trace reference + sensor location if available / missing signals

Weight and feeding-path evidence

Individual part weights by cavity / runner separately if applicable / trimming + weighing method / tested hold-time steps if relevant / locations still unconfirmed

What does the comparison support?

Defect response / other required checks / timing or measurement gaps / limits of any reported plateau

Next action / ownership

Specific evidence request / owner + review time / sample locations / product status / current authorized process state
