Géométrie
Dimensions & l'ajustement
Agree critical dimensions, références, tolerances and the measurement method before sampling.
Qualité / Inspection & validation
Quality assurance for custom injection molds
The most useful inspection plan answers a specific question: does the mold and its trial output meet the requirements agreed for this part?
Inspection methods and deliverables depend on the drawing, critical features and customer acceptance criteria.
Measure what matters to the part, document what matters to the buyer.
Project checkpoints
Inspection follows the project decisions
Checks are planned around the tool and the molded part, with customer review at the points that affect acceptance.
Before build
Define critical requirements
Identify dimensions, surfaces, matériaux, fit and functional features that need special attention in the DFM review and quality plan.
During tooling
Review mold construction
Compare key mold features with the released design and resolve deviations before they become sample issues.
At mold trial
Évaluer les échantillons
Check agreed dimensions, visible surfaces and performance-related characteristics of the trial parts. Record changes requiring another trial.
Before release
Confirm acceptance evidence
Agree which reports, sample approvals or follow-up actions are needed before the mold is approved for shipment.
Inspection scope
Focus on the part characteristics that matter
Each project has a different risk profile. The inspection discussion can cover geometry, apparence, fit and mold function without assuming one generic checklist fits all work.
Appearance
Surface review
Define the viewing conditions and acceptability of visible surfaces where appearance is important.
Function
Assembly requirements
Provide mating-part or test information for features whose performance depends on fit or movement.
Outillage
Mold operation
Review opening, ejection and other project-specific tool functions during validation.

What to send with your RFQ
Clear input makes quality expectations easier to price, plan and review. If some information is still being developed, highlight open decisions so the team can discuss them.
- Latest 2D drawing and 3D model revision
- Resin and intended end-use conditions
- Critical-to-quality features and appearance zones
- Inspection standard, report format or sample plan
- Any mating parts or functional test method
Questions courantes
Quality assurance FAQ
Can you inspect optical or cosmetic features?
Share the drawing and the required optical or appearance criteria. The team can review which inspection methods and acceptance conditions are appropriate for the part.
Which dimensions should be reported?
Prioritize dimensions affecting function, assembly and customer acceptance. Agree report points and tolerances before the mold trial.
Does approval include mold trial samples?
The sample quantity, review method and approval record should be defined in the project plan. Mold validation is linked from this page for the related process.
