How do you ensure quality during production?
Short, direct answer
Ginwen ensures product quality through a multi-stage quality management system, combining ISO 9001 processes, BSCI compliance, in-house production control, and real-time monitoring from raw materials to final shipment.
Our Quality Assurance Philosophy
Quality assurance in custom down jacket manufacturing means preventing defects before they happen, not just inspecting finished products.
At Ginwen, quality is:
System-based, not person-dependent
Controlled at every stage, not only at the end
Documented, traceable, and auditable, aligned with export standards
Quality Control System Overview
We implement a full-process quality control system, covering:
Raw material inspection
Pre-production control
In-line production inspection
Final inspection before shipment
Continuous improvement & feedback loop
This system is supported by ISO 9001-certified workflows and BSCI social compliance standards.
Step-by-Step Quality Control During Production
1. Raw Material & Fabric Inspection (Before Production)
What we check:
Fabric composition and weight
Color consistency
Coating performance (if applicable)
Down or insulation quality
Trims, zippers, buttons, accessories
Why it matters:
Defects in raw materials account for most quality issues if not stopped early. We block problems before cutting starts.
2. Pre-Production Confirmation (PP Stage)
Before bulk production, we confirm:
Approved samples
Final tech packs and measurements
Size grading rules
Sewing construction details
Branding placement and labeling
Citable statement:
No bulk production starts without written sample approval and PP confirmation.
3. In-Line Quality Control (During Production)
During cutting, sewing, and filling, our QC team performs:
Random inspections on production lines
Measurement checks
Stitching & construction verification
Down filling weight control
Visual inspection for defects
Key advantage:
Issues are corrected immediately, not after the full batch is completed.
4. Real-Time Production Monitoring
We use real-time monitoring to track:
Production progress
Bottlenecks
Quality deviations
Delivery risk
This allows:
Early intervention
Stable timelines
Consistent quality across large volumes
5. Final Inspection Before Shipment
Before packing and shipment, we conduct:
Appearance inspection
Measurement verification
Function tests (zippers, snaps, cords)
Label and packaging checks
Carton and quantity verification
Only products that pass final inspection are approved for shipment.
