Quality-Based Production Process — How Every Kingsons Bag Is Made

Every bag that leaves the Kingsons facility has passed through five defined production stages, each with its own quality checkpoint. This is the process — from raw material selection through to final inspection before packing.

Raw Material Selection
1

Raw Material Selection

Only high-grade fabrics from vetted suppliers enter production: nylon imperméable, polyester (900D/1800D), Tissu Oxford, cuir microfibre de première qualité, Santé mentale, and certified eco materials (RÉPÉTITION, PU biosourcé). Each material batch undergoes incoming inspection — off-spec materials rejected. Matériel (YKK/SBS zippers, buckles, D-rings) batch-checked on arrival. GRS-certified RPET available for eco product lines.

Design Development
2

Design Development

80 engineers transform client briefs into precise technical drawings, pattern specifications, and production-ready files. For OEM: technical drawings from your design with engineering optimization. For ODM: design from concept with R&D team leading from sketch to sample. CAD pattern development ensures dimensional accuracy and reduces material waste. Sortir: approved technical package + material spec sheet.

Automated Cutting
3

Automated Cutting

Intelligent digital cutting system: computer-controlled equipment executes pattern cuts with consistent dimensional accuracy across every production run. Digital cutting eliminates manual variation — every panel cut to same spec whether first or ten-thousandth unit. Automated nesting optimization reduces fabric waste. Scalability without quality compromise: rapid scale-up from sample to full production. Cut panels checked against approved pattern spec before sewing.

Sewing & Assembly
4

Sewing & Assembly

Skilled craftsmen and automated lines work in combination. Reinforced stitching at all stress points — handles, strap attachments, zipper seams, base panels. Hardware fitting (buckles, D-rings, zipper pulls, USB port housings) under workstation-level quality checks. In-line sewing QC: supervisors check stitch consistency, seam alignment, hardware placement at regular intervals — defects caught within batch. Résistance à la traction des coutures minimum 800N (QB/T 3826 standard).

Rigorous Product Inspection
5

Rigorous Product Inspection

Multi-point quality inspection against approved spec: dimensional accuracy, stitching quality, hardware function, fabric surface, logo application, aesthetic presentation. Physical performance tests per batch: handle stress 500 cycles @ 7KG, secondary handle 350 cycles @ 7KG, endurance de la fermeture éclair 5,000-12,000 cycles @ 350N, seam strength min 800N. Defect classification: Critical (rejected), Major (batch hold), Minor (rework). Final Inspection Report with every shipment.

Quality Control — Multi-Stage, In-Line, and Independently Certified

Quality control at Kingsons is not a final-stage gate — it is built into every step of the production process. By the time a finished bag reaches the final inspection station, it has already passed quality checks at raw material intake, pattern cutting, couture, and hardware assembly.

Layer 1 — ISO 9001 Système de gestion de la qualité certifié

  • OIN 9001 certification means Kingsons’ quality management approach is structured to an internationally recognized standard and externally audited on a regular cycle
  • QMS covers: documented process controls at every production stage, defined quality standards per product category, non-conformance reporting and corrective action procedures, supplier qualification management, customer complaint tracking and resolution
  • Third-party audit cycle: annual surveillance audits and full recertification every three years — quality system continuously verified

Layer 2 — In-Line Production Quality Checkpoints

  • Incoming material inspection: All fabric and hardware batches checked against specification on arrival. Off-spec materials rejected before entering production.
  • Pattern cutting checkpoint: Cut panels verified against approved technical drawing for dimensional accuracy before proceeding to sewing.
  • In-line sewing supervision: Supervisors monitor stitch consistency, seam alignment, hardware placement at regular intervals during the sewing run.
  • Hardware fitting check: All functional components (zippers, buckles, USB ports, magnetic clasps) tested for correct operation immediately after fitting.
  • Pre-packing final inspection: Every unit inspected against the full product specification checklist before packing.

Layer 3 — Physical Performance Testing Standards

  • Defined performance tests applied to production samples from each batch — results documented in shipment QC report
  • Handle/strap stress test: 500 cycles à 7KG de charge soutenue
  • Test de contrainte de la poignée secondaire: 350 cycles à 7KG de charge
  • Zipper cycle endurance: 5,000-12,000 cycles at 350N applied force
  • Résistance à la traction des coutures: minimum 800N at 100±10mm/min pull rate (QB/T 3826)

Layer 4 — Defect Classification & Reporting

  • Every defect classified by severity: Critical (unit rejected from shipment), Major (batch held for full re-inspection), Minor (unit reworked and re-inspected)
  • Defect data tracked per production run and per product category — enabling systematic identification of recurring issues and targeted process improvement
  • Final Inspection Report issued with every shipment, documenting inspection scope, defect findings, and pass/fail outcome
  • Clients requiring third-party pre-shipment inspection can arrange independent QC inspectors — Kingsons cooperates fully with client-nominated inspection agencies
