The 6-Stage Inspection Protocol

From incoming leather material receipt to container sealing, each production batch undergoes mandatory verification milestones. Hover over any stage to examine specific testing parameters and acceptance criteria.

texture STAGE 01

Material Inspection

Comprehensive verification of raw materials prior to release into cutting. We check appearance, consistency, color matching under standard D65 illumination, substance thickness, and finishing of leather, fabrics, and hardware components.

check_circle Incoming leather grading & grain uniformity audit
check_circle Calibrated digital micrometer thickness grading
check_circle Hardware plating & anti-corrosion verification
Pass Criteria: 100% Raw Spec Compliance verified
precision_manufacturing STAGE 02

Production Monitoring

Inline process checks executed at critical workstations to identify and correct issues early during cutting, skiving, stitching, and sub-assembly. Defective components are segregated immediately before assembly proceeds.

check_circle Die-cutting accuracy & grain direction alignment
check_circle Skiving bevel angle & edge thickness calibration
check_circle First-piece hourly line inspection audits
Intervention: Real-Time Machine Correction verified
handyman STAGE 03

Workmanship Control

Detailed scrutiny of artisan assembly techniques, seam alignment, edge finishing, hardware fitting, printing, and embroidery. Ensures needle tension, stitch per inch (SPI) counts, and bonding compounds meet premium export standards.

check_circle Consistent SPI (Stitches Per Inch) & back-tacking
check_circle Smooth edge burnishing, creasing & paint seal
check_circle Embossing clarity, foil adhesion & embroidery density
Standard: European Luxury Finishing Norms verified
straighten STAGE 04

Size & Specification Checks

Measuring critical dimensions, verifying fitting, and checking component placement against approved size charts and technical sheets. Every batch is benchmarked against signed buyer tech-packs to ensure exact anatomical fit.

check_circle Multi-point dimensional verification against tech-pack
check_circle Ergonomic fitting validation on calibrated master lasts
check_circle Pocket, strap, D-ring & buckle coordinate audit
Tolerance: Strict ±1.5mm Dimensional Limit verified
search_check STAGE 05

Final Product Inspection

Full visual examination, cleanliness check, functional hardware testing, and branding conformity prior to final packing. Finished products must pass a comprehensive 360-degree cosmetic and mechanical inspection checklist.

check_circle 100% cosmetic examination & loose-thread cleaning
check_circle Mechanical cycle tests: zippers, snaps & buckles
check_circle Golden Master comparison sign-off before packaging
Standard: ANSI/ASQ Z1.4 Level II Normal verified
package_2 STAGE 06

Export Packaging Inspection

Verification of branded retail packaging, polybags, barcodes, hangtags, carton markings, master cartons, and export container stuffing. Guarantees zero retail chargebacks and total freight protection against maritime moisture.

check_circle 100% barcode readability & SKU matching scan test
check_circle Heavy-duty 7-ply corrugated master carton drop testing
check_circle Desiccant silica gel inclusion & pallet banding integrity
