7-Stage Quality Control
Process Flow

A systematic, end-to-end quality assurance framework applied to every order -- regardless of size or complexity.

01

Raw Material Inspection

All incoming leather, hardware, thread, and lining materials are inspected for color consistency, texture, thickness, and defect-free surfaces before production begins.

Color Check Thickness
02

Sample Approval

Pre-production samples are crafted and submitted for customer approval. Dimensions, stitching patterns, hardware placement, and finishing are verified against approved specifications.

Prototype Approval
03

Cutting & Prep QC

Precision cutting templates ensure uniformity across all pieces. Each cut panel is checked for dimensional accuracy, clean edges, and grain alignment before assembly.

Precision Cut Uniformity
04

In-Process Inspection

QC supervisors conduct rolling inspections at each production station -- stitching tension, gluing, edge finishing, and hardware installation are monitored in real time.

Stitching Hardware
05

Durability & Function Testing

Products undergo zipper pull tests, seam stress tests, colorfastness testing, and closure mechanism cycling to verify long-term durability and functional reliability.

Stress Test Colorfastness Zipper Cycle
06

Final 100% Visual Inspection

Every finished product is individually inspected under standardized lighting for surface defects, stitching consistency, branding accuracy, and overall appearance before packaging.

Visual QC 100% Check
07

Pre-Shipment Verification

A final pre-shipment audit confirms quantity accuracy, packaging integrity, labeling compliance, and documentation completeness before goods are released for export.
