Magnet-related questions should be tied to the exact SKU, sample and destination market. A picture can show a housing; it cannot by itself prove retention, test scope or production consistency.
Ask for the model-specific construction record
Request the current component description, enclosure method, revision and any available magnet-related specification for the selected model. Keep flat magnetic tiles and magnetic blocks as separate product forms in the record.
- Where is the magnet enclosed in this SKU and production version?
- What visual or dimensional checks are performed on the enclosure?
- Which evidence covers the exact model, material, age grade and destination?
- What change-control step applies if the magnet, housing, adhesive or shell changes?
- How are sample findings recorded and carried into the production inspection plan?
Use observation and evidence for different jobs
During sample review, record cracks, openings, sharp edges, loose parts, inconsistent joins or visible changes. Label these as observations. A visual check does not replace an applicable laboratory report or other technical evidence, and a generic report should not be treated as coverage for every SKU.
Set a release gate
- Freeze the SKU and sample reference.
- List unresolved magnet and enclosure questions.
- Request model-matched answers or documents.
- Record who approves any change.
- Recheck the first production evidence against the approved reference.
FAQ
Can a visual inspection prove retention performance?
No. It records visible condition; request model-matched technical or test evidence for performance questions.
Should buyers specify a magnet grade from a catalog?
Only when the supplier confirms it for the exact SKU and production version.
What if the sample changes after approval?
Pause release, document the change and re-evaluate affected evidence.
