01
Approved configuration
Freeze released part files, resin, tool revision/cavity state, texture/finish and approved assembly or post-process requirements.
Evidence route
Release index and signed configuration baseline
Moulding production control
Injection-moulding production release: approve a repeatable process, not just a set of good parts.
Production release connects the approved part, exact resin, current tool, qualified machine route, process window, control plan, golden samples and change rules. PartVerity keeps product evidence and process evidence together at the handover to serial supply.
Decision premise
Release question: which controlled combination of product, tool, material and process may now produce accepted parts?
Engineering control
Six controls for moulding production release
The validation depth depends on product risk, contract and industry. Not every project requires a regulated qualification package, but every release needs a defined basis.
02
Process-window evidence
Define machine/tool setup and challenged or demonstrated parameters at the depth required by project risk.
Evidence route
Process study/parameter record and authorised operating range
03
Product verification
Close dimensional, visual, functional, material and compliance requirements using identified samples and actual results.
Evidence route
Approved inspection/validation package and NCR status
04
Control plan
Set incoming, in-process and final checks, frequency, method, reaction plan and record retention for CTQs and process signals.
Evidence route
Released control plan, work instructions and gauges
05
Reference state
Control golden/limit samples and setup masters by revision, cavity, date, storage and replacement authority.
Evidence route
Reference-sample register and accessible approved standards
06
Change and lot control
Define triggers for material, tool, machine, site, process, repair or supplier changes and retain production lot genealogy.
Evidence route
Change-notification rule, batch record and release owner
Decision matrix
Release input to ongoing control
A complete release basis prevents a one-time sample approval from becoming an unlimited production claim.
| Release input | Control decision | Ongoing record |
|---|---|---|
| Approved dimensions | Which CTQs continue in production checks? | Lot-linked actual results and reaction status |
| Established process window | Which parameters and setup factors are controlled? | Machine/run record and approved deviations |
| Golden visual sample | Which zones and viewing conditions apply? | Sample identity, condition and disposition history |
| Tool maintenance | Which events trigger inspection or revalidation? | Cycle/run context, work performed and post-maintenance result |
| Material or site change | What approval and evidence must repeat? | Change request and authorised validation scope |
Claim boundaries
What sample approval does not automatically authorise
A different resin grade, colour or regrind rule.
A different tool revision, cavity state, machine route or production site.
Unrecorded process drift outside the released basis.
Shipment while open non-conformances lack authorised disposition.
Technical context
Use guidance to frame the review—not to replace project evidence.
External context for qualification layers, process windows, repeatability and traceability. Validation depth remains product-, contract- and industry-specific.
