Quality is our core commitment to customers. Certified to ISO 9001:2015, we maintain a standardized, traceable closed‑loop quality system with measurable quality objectives. We implement four‑level inspection: IQC‑IPQC‑FQC‑OQC, combining manual QC monitoring and auto‑inspection equipment to guarantee consistent batch‑to‑batch quality.

• Incoming Inspection Pass Rate: 100%
• First‑Article Inspection Pass Rate: 100%
• Final Inspection Pass Rate: ≥99.7%
• On‑time Delivery Rate: ≥100%
• Customer Satisfaction Rate: ≥99%

All production procedures follow ISO 9001:2015 requirements. Full‑process traceability and standardized site management are implemented. We continuously improve management rules and product performance to stabilize manufacturing and minimize batch variation.

IQC Incoming Inspection Raw materials are inspected before warehousing. Non‑conforming materials are rejected to avoid upstream quality risks.

IPQC In‑Process Inspection Dedicated QC monitors key parameters: color difference, register accuracy, ink adhesion. Automatic inspection system detects misalignment, ink spots, print blurriness for dual quality protection.

FQC Finished‑Goods Inspection Finished labels are checked on appearance, dimension and finishing effects. Performance tests including adhesion, abrasion‑resistance and temperature‑resistance are carried out. Defective products are isolated.

OQC Pre‑Shipment Inspection Final verification before dispatch. Goods can only be packed and shipped after passing all inspection items.

Test records of every batch are well‑documented. We conduct regular quality reviews to optimize processes, inspection tools and management standards, delivering reliable printing labels for global partners.
