Program enters long-term supply phase.
While the development and production release process ensures design and process readiness, long-term supply stability depends on continuous quality control throughout daily manufacturing operations.
Production Quality System
Consistent product performance relies on continuous quality monitoring and controlled inspection processes throughout daily manufacturing operations, not only during development stages.
①: Incoming Material Verification
- Supplier qualification and material specification control
- Batch identification and traceability
- Sampling inspection based on defined acceptance criteria
②: In-Process Quality Monitoring
- Key process parameter checks at critical operations
- Operator self-check and mutual inspection mechanis
- Process deviation reporting and escalation workflow
③: Assembly and Functional Verification
- Assembly torque and sequence control
- Leakage and basic functional checks after assembly
- Early detection of abnormal noise or vibration
④: End-of-Line Performance Testing
- Flow, pressure, and efficiency testing
- Noise and stability testing when required
- Test records linked to production batches
⑤: Traceability & Corrective Actions
- Batch traceability from material to finished product
- Root cause analysis for detected issues
- Corrective and preventive action implementation
Quality Control in Practice
These examples illustrate how quality controls are implemented directly on the production floor, beyond written procedures and inspection plans.
