Dimensional checks
Identify critical features and the inspection method required to compare trial parts with the drawing.

Trial and acceptance
Mold Validation
Use trial parts and agreed inspection criteria to decide what is accepted, what changes and what needs another review.
Make acceptance criteria visible before the trial
The inspection plan should reflect the drawing, resin, appearance requirements and the sample conditions agreed for the project.
Visual review
Agree which surfaces and defects matter to function, assembly or appearance.
Functional fit
Where needed, check assembly, mating features and use-related characteristics.
Review record
Capture results, deviations, requested changes and the next approval decision.
Evidence should match the decision
Choose reports and sample evidence around the critical-to-quality features. A machine photo or a measurement alone does not establish acceptance.
For each issue, record the drawing revision, measured or observed condition, proposed action and customer response.
Trial to release
Keep the status of samples and changes clear across each review cycle.
Plan the trial
Agree the intended sample quantity, material and review criteria.
Evaluate samples
Inspect the agreed features and share findings with the customer.
Close open issues
Document changes and retest items that affect acceptance.
Confirm handover
Record approvals and the deliverables agreed for shipment or production transfer.
Common questions
Is one mold trial always enough?
The required number of reviews depends on the result and the agreed acceptance criteria. Open issues may require another trial.
What should be approved before release?
Confirm the sample status, drawing revision, required inspection evidence, remaining issues and handover items.
