How should a buyer review a dimensional inspection report before approving a GEERPOWER export injection mold?
Review whether each critical dimension is tied to the correct drawing revision, sample identity, cavity number, measurement method, tolerance, actual value, deviation status and correction action. Keep tolerance pass, capability, sample approval, lab accreditation, price and delivery as NEEDS_EVIDENCE until documented for the exact mold project.
Decision checklist
- Confirm the report uses the same drawing revision approved for mold construction.
- Match every sample to date, cavity, resin, color, process sheet and trial stage.
- Check whether the measurement method is suitable for each critical feature.
- Separate corrected deviations from accepted deviations and still-open deviations.
Review the report as traceable evidence
An export mold sample can look acceptable while critical dimensions remain unverified, measured against the wrong drawing revision or left with unclear deviations. The report should be a traceable evidence package, not a single OK statement.
NIST metrology resources reinforce the importance of measurement science and traceability, while Protolabs design guidance shows why wall thickness, ribs, bosses and geometry affect molded-part outcomes. These sources support the inspection logic; they do not prove a GEERPOWER sample passed.
Dimensional report review table
Use the worksheet below before approving a mold shipment or sample stage. Project-specific tolerances, sampling and disposition rules must come from the buyer's drawing and agreement.
| Report item | Buyer should request | GEERPOWER should clarify | Hold point |
|---|---|---|---|
| Drawing control | Drawing revision, ballooned dimensions and critical marks | Which revision was used for mold cutting and inspection | Drawing and report revisions disagree |
| Sample identity | Date, cavity, material, color and process sheet | Whether samples represent T0, T1 or pre-shipment trial | Samples cannot be traced to the report |
| Measurement method | CMM, gauge, fixture, caliper or optical method | Which method is suitable for each tolerance | The method is missing or too broad |
| Results | Nominal value, tolerance, actual value and deviation | Which deviations are accepted, corrected or still open | Pass or fail is not tied to values |
| Mold response | Correction record, steel-safe change or concession | Whether action changes mold, process or buyer spec | The deviation has no closure owner |
Do not treat first samples as capability proof
A first dimensional report can support mold correction and sample approval, but it does not prove process capability by itself. Capability requires a defined run, sampling plan, stable process and agreed calculation method for the exact project.
The buyer should also distinguish functional dimensions from cosmetic or reference dimensions. A feature that is easy to measure is not automatically the most important feature for assembly, sealing, movement or long-term use.
- Released drawing revision and ballooned inspection plan
- Sample lot, cavity identity and retained samples
- Measurement method and equipment or fixture basis
- Deviation list, correction action and retest requirement
Route open evidence into project review
GEERPOWER should avoid wording that implies all dimensions passed, a CMM program is validated, a lab is accredited, process capability is proven, samples are approved, price is fixed or delivery is committed without exact project evidence.
Send part drawings, ballooned dimensions, T0 or T1 samples, inspection reports, CMM screenshots, deviation notes and correction records through the GEERPOWER project review path. The response should separate confirmed dimensional evidence from every item that remains NEEDS_EVIDENCE.
External measurement and design references do not verify a GEERPOWER project, inspection report, sample pass, lab status, price or delivery.
Common buyer questions
Is a sample photo enough to approve an export injection mold?
No. Photos help with visible defects, but dimensional approval needs a drawing-linked report, sample identity, measurement method, actual values, deviation status and correction closure.
Does one passed sample prove process capability?
No. A first report can support mold correction and sample review, but capability requires a defined run, sampling plan, stable process and agreed calculation method.
Can NIST or Protolabs sources prove a GEERPOWER sample passed?
No. The sources support measurement and injection molding design principles. They do not verify a GEERPOWER project, CMM report, sample pass, lab status, price or delivery.
