Quality Control System
At Luxzipper, quality is controlled throughout every stage of production, from raw material inspection to final shipment. Our quality control system combines material verification, in-process inspections, 100% final inspection and batch performance testing to ensure consistent product quality.
Raw Material Control
All raw materials are inspected before entering production and are traceable by batch.
Incoming materials are verified against internal quality standards to ensure consistency, safety and compliance requirements.
Regular inspections help maintain:
In-Process Inspection
Quality inspections are conducted throughout production to ensure manufacturing consistency.
Key processes including dyeing, chain production, die-casting and assembly are monitored according to standardized inspection procedures.
100% Final Inspection & Batch Testing
Every finished zipper undergoes 100% visual and functional inspection before packing.
In addition, each production batch is sampled for performance testing to verify durability and consistency.
Only products that pass both inspection and testing requirements are approved for shipment.
