Located on each production floor, this area serves as the core quality control checkpoint and follows the workflow below: 1. Abnormality Trigger When an abnormality is detected by IPQC or the SPC system triggers an alert, the system automatically generates a Process Abnormal Notification Form. 2. Initial Containment • Immediate lot control: Quarantine affected product batches from the abnormal production period. • Physical isolation: Use red isolation tags to mark suspected non-conforming products. • Escalation: Notify Production Supervisors and Quality Engineers immediately. 3. Abnormality Resolution Emergency response: • Production technicians execute E-Stop and complete the Equipment Downtime Log. • Equipment/Process Engineers conduct Root Cause Analysis (RCA). Post-recovery actions: • Machine capability verification (Cmk ≥ 1.67). • 5 consecutive self-inspected parts meeting specifications. • Submit first-off samples to IPQC for MSA verification. 4. Closed-Loop Management Corrective action: • Production team submits an 8D Report via the QMS within 4 hours. Validation: • IPQC engineers track process capability (CPK ≥ 1.33) across 3 consecutive production batches. • Quality Manager approves and closes the abnormal case.
