Quality Control
This page outlines operational QC checkpoints used in chainsaw-chain B2B supply programs, from raw material intake to pre-shipment release and post-delivery issue handling.
1) Process Control Plan
| Stage | Control Focus | Record Type |
|---|---|---|
| Incoming Material | Steel lot verification, chemistry confirmation, and traceability coding. | Material certs and incoming inspection logs. |
| In-Process Control | Pitch/gauge dimensional checks, hardness sampling, and assembly integrity checks. | Process QC sheets and non-conformance records. |
| Final Inspection | AQL-based visual and dimensional review before packing release. | Final release checklist and lot acceptance report. |
| Pre-Shipment | PO-level verification of label accuracy and packaging configuration. | Pre-shipment inspection summary. |
2) Verification Items Used by Buyers
Dimensional Accuracy
Pitch/gauge/drive-link conformance against approved specification windows.
Hardness Consistency
Batch-level hardness validation for cutter and drive-link consistency control.
Assembly Integrity
Rivet condition, chain articulation, and loop integrity before release.
Packaging Accuracy
Correct SKU labels, carton marks, and document matching before dispatch.
3) Issue Escalation and Corrective Loop
- Buyer submits SKU, lot, and evidence package (images and field conditions).
- Quality team traces lot records and checks inspection history.
- Root-cause and containment actions are issued for confirmed deviations.
- Corrective action summary is shared and linked to replacement/credit handling when applicable.
