Traceability

Connected records from customer requirement to lot release.

Records behind each lot

Traceability is not paperwork added after production. It is the record path that follows each lot from the first customer requirement to final release.

When a part leaves Sanjin, the related requirement, internal drawing version, production order, inspection result, and shipment record can be traced back clearly.

Record path

A lot record connects the key steps from order intake to shipment release.

01

Order record

Customer requirement, drawing version, quantity, delivery need, and special notes are recorded before work begins.

02

Job file

The order is linked with internal instructions, material requirements, and the planned production route.

03

Lot record

Key shop-floor steps and required checks are attached to the lot as work moves forward.

04

Inspection record

Dimensional, visual, surface, plating, or other required results are kept with the lot.

05

Release record

Final release, packing, shipment information, and inspection reports connect back to the same lot history.

What can be checked later

When a delivered lot needs to be reviewed, the record should answer the practical questions clearly.

  • Which customer requirement, order, and drawing version was used.
  • Which internal work order and production route the lot followed.
  • Which inspection steps were completed before release.
  • Which inspection report, packing record, and shipment record belong to the lot.
