Mastering Quality Control in Chinese Manufacturing
Professional Guide to Implementing Effective Quality Control Systems
Effective quality control is crucial when manufacturing in China. This comprehensive guide outlines professional QC strategies and best practices to ensure your products meet quality standards consistently.
The Three Stages of Quality Control
1. Pre-Production Inspection
- Raw material verification
- Component quality check
- Production preparation
- Specification review
Timing: Before production starts
2. During Production Inspection
- Process monitoring
- Quality checkpoints
- Production standards
- Defect identification
Timing: At 15-80% completion
3. Pre-Shipment Inspection
- Final quality check
- Quantity verification
- Packaging inspection
- Shipping preparation
Timing: Before shipment
