Quality Control
Every fly screen, pleated screen, pleated blind, honeycomb blind, venetian blind and zip blind is audited by a six-person quality cell. Scratches, bent profiles, broken corners, paint defects, inner/outer coating, cord tension and assembled performance are reviewed in detail to guarantee flawless operation on site.
| Checkpoint | Methodology | Threshold | Decision Flow | Owner |
|---|---|---|---|---|
| Surface & paint | Spectral scan + visual inspection | ΔE ≤ 1 / ±5µm film | Deviation -> quarantine -> repaint | Paint lead |
| Profiles & frames | Laser gauge + bending fixture | Warp >0.3 mm rejected | Quarantine -> rework lane | Mechanical supervisor |
| Cord tension | Torque sensor + manual pull | ±7% tolerance | Adjust cord -> retest | Assembly chief |
| Installation simulation | Wall jig + wind tunnel | 5,000 cycle endurance | Failure -> rebuild | QA lead |
| Pre-pack | Visual + RFID log | Zero defect | Defect -> quarantine & scrap/rebuild | Quality team |
Quarantine Protocol
- Each unit receives an RFID event; deviations route it automatically to the quarantine area.
- The quality lead, production owner and shift manager decide whether to rework, remake or scrap.
- Units exit quarantine only after repeating the entire test stack.
- Critical failures (broken profiles, wrong fabric, faulty motors) trigger root-cause analysis.
- No logistics label is printed until the technician signs off the fix.
- The full chronology is visible to brands and dealers for traceability.
Field Performance Add-ons
- Installation videos are linked via QR inside the box for installers.
- 30-day post-install feedback updates the defect matrix.
- Components are serialized so service teams can trace them on site.
- Child-safety accessories, sharp edges and cord heights are double-checked.
- Random units undergo field A/B tests; learnings feed the production recipe.
- Supplier quality assurance reports are published weekly.
