The Quality-Control System Behind Every DiBiBi Order

Five documented control processes — incoming, production, packaging, shipment and complaint handling — run by an independent QC department under procedure DBB/QG PZ-0001.

Four Principles Behind the Checks

01

Prevention First

Controls built into work instructions and tooling, not bolted on at the end.
02

Full Traceability

Every batch tied to its material lot, line, operator and inspection record.
03

Independent QC

A dedicated QC department reports separately from production output targets.
04

Documented Proof

Inspection reports and feedback notices logged and filed for every order

Five Gates From Raw Material to Your Dock

Each stage is a documented flow (procedure DBB/QG PZ-0001) with defined responsible departments and record forms. Product only advances when it clears the gate before it.

Incoming Material Control

Warehouse notifies QC on arrival; IQC inspects against work instructions and drawings. Non-conforming lots are root-caused (material vs. design), resolved with the supplier or engineering, and a preventive action is filed.

Responsible: QC · Production

In-Process Production Control

Operators self-check per work instruction; IPQC runs first-article approval and roving inspection. Defects are tagged and isolated; non-conforming parts go to rework, downgrade or scrap, and line abnormalities escalate to the QC supervisor.

Packaging Control

Pre-pack material check, packing self-check, then first-article and roving inspection against the packing instruction. Finished packs pass a QA inspection by sampling standard before they enter the finished-goods warehouse.

Responsible: QC · Warehouse

Finished-Goods & Shipment Control

Finished goods move to the FG warehouse, where QA runs the pre-shipment (customer) inspection. Passing lots ship; non-conformances trigger correction and prevention with the responsible department before release.

Responsible: QC · Sales

Customer-Complaint Process

QA receives and logs every complaint; technical and quality teams make an initial judgement. Customer-factor issues route to sales; confirmed product issues are verified against WIP and finished stock, resolved, and closed with a documented preventive action.
