Appearance & Dimensional Inspection
Dimensional Integrity and Edge Condition Verification
The geometry of the magnet is examined to ensure compliance with specified tolerances. Edges and corners are checked for uniform chamfering or controlled rounding to eliminate burrs, micro-cracks, or stress concentration points resulting from cutting and grinding operations.
Surface Cleanliness Evaluation
Magnet surfaces are assessed for the presence of contaminants such as machining fluids, particulate matter, handling residues, or other foreign substances that could negatively impact coating adhesion, assembly accuracy, or subsequent processing steps.
3.3 Inspection Methodology and Acceptance Criteria
Visual quality assessment is performed in accordance with established inspection procedures, using defined sampling levels and acceptance limits based on internal control standards or customer-approved specifications to ensure consistent and repeatable quality outcomes.

FAQ
Q1. How does long-term aging differ from short-term high-temperature exposure?
Short-term exposure mainly causes immediate irreversible loss, while long-term aging can lead to gradual performance decay due to microstructural changes, oxidation, and repeated thermal stress.
Q2. Is irreversible loss fully predictable from datasheet curves?
No. Datasheet curves are generated under controlled conditions and do not fully account for complex magnetic circuits, mechanical stress, or thermal cycling present in real applications.
Q3. Why do magnets sometimes pass initial tests but fail after months of operation?
Delayed failures are often linked to marginal coercivity design, coating microcracks, or cumulative thermal and magnetic stress not covered in initial qualification tests.
