Engineering conditions

Use 5 key conditions to see how the assessment order changes.

First align parting/sealing-surface flash and resin keep-out contamination with mold contact and actual clamping/cavity pressure. Then separate sealing geometry from resin flow. Underfill fillets or panel-handling issues cannot substitute for sealing-window evidence. Unknowns remain unconfirmed. “Ready for assessment” means only that the method inputs are complete; it does not mean a diagnosis or qualification has been established.

Confirmed: 0 / 5 conditions0 paths ready for initial assessment

Sealing and observations

Is flash located on mold parting/sealing surfaces and clearly defined resin keep-out zones, with a traceable demolding stage?Retain die-edge underfill fillets, macroscopic short shots and unstable chucking/handling as separate adjacent topics. Resin keep-out zones need product-specific definitions.

Are flash maps at the same location, mold-contact/inspection records and known-good molding-cycle comparisons available?Endpoint thickness or photos after cleaning cannot reconstruct sealing contact. Retain cycle records, both mating surfaces, contamination/wear inspections and evidence-collection limitations.

Are actual clamping, cavity pressure/temperature and molding cycles synchronized, with measurement locations clearly identified?Nominal clamp tonnage or hydraulic settings are not the sealing-surface contact distribution. Actual history and uncertainty are needed; increased pressure is not a general solution.

Geometry and flow

Can sealing surfaces/support, wear-state versions, inserts and the presence/configuration of release film be traced?Material or film names are insufficient. Actual contact geometry and inspection methods are required. Public equipment capabilities do not provide acceptance criteria for this sealing gap.
