Quality Control at Dongguan Yangqi Hardware Co., Ltd.

At Dongguan Yangqi Hardware Co., Ltd., quality control is the foundation of everything we do. For 25 years, our commitment to excellence has been built into every step of production — ensuring every piece of custom metal hardware, from handbag hardware and dog name tags to outdoor buckles, meets the highest standards of quality and performance.

Here's how we maintain and elevate product quality:

1. International Standards Compliance

We strictly adhere to international quality standards, including ISO 9001 quality management and ISO 14001 environmental management certifications, with RoHS and REACH compliant products. Regular third-party testing by SGS and Intertek validates our compliance — ensuring consistent quality and giving global buyers confidence.

2. Three-Stage Inspection with 100% Pre-Shipment Check

Our quality control process covers every stage from raw material to finished product:

• First Article Inspection: The first piece of every batch undergoes full dimensional, cosmetic, and functional testing before mass production begins.
• In-Process Inspection: Regular checks during die casting, polishing, and plating catch and correct issues early.
• Pre-Shipment Inspection: 100% inspection before every shipment — dimensions, plating thickness, salt spray, functional testing — nothing skipped, with an inspection report included in every shipment. Defect rate: below 0.5%.

3. Durability and Functional  Testing

We know hardware takes daily wear, so we test every product category for real-world performance:

• Salt Spray Testing: 48-hour neutral salt spray testing verifies corrosion resistance — no rust in outdoor or humid environments.
• Plating Thickness Testing: Precise measurement of electroplating and PVD coating thickness ensures color holds for 3–5 years.
• Pull and Cycle Testing: Repeated opening/closing and load testing on buckles, magnetic snaps, and zipper pullers verifies long-term reliability.
• Functional Testing: Every clasp closes securely, every zipper slides smoothly, every magnetic snap holds steady.

4.  Attention to Every Detail Our QC team checks every detail with precision:

Our QC team checks every detail with precision:
Dimensional Accuracy: Critical dimensions held within ±0.1mm tolerance.
Cosmetic Inspection: Scratches, bubbles, color variation, and uneven plating — all checked and rejected.
Functional Integrity: Every piece is individually tested after assembly, ready to use out of the box.

5.  Continuous Improvement

We believe in continuous improvement. Every year we invest in new equipment and process upgrades — automated polishing, eco-friendly plating, PVD vacuum coating — staying current with industry trends and the latest technology to keep our quality and innovation at the forefront.

Dongguan Yangqi Hardware Co., Ltd. is committed to delivering the highest quality custom metal hardware components. Our rigorous quality control and commitment to international standards ensure every product we ship is reliable, durable, and finely crafted.
