QUALITY ASSURANCE

Quality assurance

Match drawings and technical requirements with inspection methods, acceptance criteria and audit documents.

04 / QUALITY ASSURANCE

Each requirement
needs a corresponding check.

Align drawings, samples, test methods and acceptance criteria to support sample validation and supplier audits.

Discuss validation & audit documents ↗

Inspection scope and sampling arrangements follow the component's technical requirements.

01Dimensions & appearance+

Vision measurement, thickness sorting, height measurement and automated inspection support checks on critical dimensions, mating surfaces and appearance. Inspection scope follows component requirements.

02Material & finished magnetic properties+

Permanent-magnet characterization checks material demagnetization curves. Fluxmeters and teslameters measure component flux and surface fields respectively. Use consistent conditions and acceptance criteria when comparing samples and batches.

03Coatings & environmental durability+

X-ray fluorescence supports coating measurement. Salt spray, temperature/humidity and high-temperature aging equipment support related validation. Sample condition, methods, duration and criteria are agreed by project.

04Management systems & supplier audits+

Discuss quality and environmental management documents, material declarations and test documentation. Certificate entity, scope and validity follow current documents; product records must match the supplied material and treatment.

CCD / VISION INSPECTION

Clear criteria
for visual inspection.

Discuss imaging conditions, acceptance criteria and sorting for CCD vision inspection against appearance and dimensional requirements. Detectable features and inspection scope must be confirmed with samples.

From samples to inspection conditions

  1. 01 · Imaging conditions

    Confirm lighting and imaging methods for the component surface, shape and inspection position.

  2. 02 · Acceptance criteria

    Define the features to identify using drawings, limit samples and agreed standards.

  3. 03 · Sorting & review

    Discuss sorting, review and exception feedback for project requirements.

TESTING / METHODS FOR EACH REQUIREMENT

Verify material data and component performance separately.

Material magnetic properties

Company materials list an AMT-4 permanent-magnet characterization instrument for demagnetization curves. Confirm properties using agreed temperatures, samples and methods.

View material reference data →

Finished component magnetism

Fluxmeters measure magnetic flux; teslameters measure surface fields. Standardize fixtures, positions, distances and magnetization state before comparing batches.

Discuss component acceptance methods →

Coatings & environment

Company materials list X-ray fluorescence, salt-spray and temperature/humidity equipment. Match coating thickness and environmental tests to the actual sample.
