Quality Management
Quality management at YO JYI covers incoming material inspection, in-process checks during stamping and assembly, and final inspection before shipment, with records retained for traceability. This page sets out the inspection stages applied to production and how non-conformance is handled.
Quality Policy
Production is planned around inspection checkpoints at each stage — incoming material, in-process production and final part — rather than relying on inspection at the end of the line alone.
Inspection Stages
Incoming Inspection
Incoming raw material is checked against specification before it is released to production.
In-process Inspection
Parts are checked at defined intervals during stamping, forming and assembly.
Final Inspection
Finished parts are checked against the drawing before packaging and shipment.
Measurement & Checks
- Dimensional checks against drawing tolerances
- Visual inspection for surface and finish defects
- Functional checks for assembled components
Specific measurement equipment models will be listed here once confirmed with YO JYI.
Traceability
Production and inspection records are retained per order, so a finished part can be traced back to its production run and inspection results.
Packaging
Packaging is coordinated with production scheduling to suit export shipment, with specific packaging methods confirmed per order and product.
Corrective Action
- Non-conforming parts are identified and segregated
- Root cause is reviewed before production resumes
- Corrective actions are recorded against the affected order
Certifications
Certifications will be listed here with issuing body and validity once verified with YO JYI. Only certifications currently held are published, per company content policy.
