Introduction: Setting the Standard for Global Quality
At Winko International, quality is not an afterthought — it’s the foundation of everything we create.
For over six decades, we’ve refined our manufacturing processes to ensure that every product, from home décor to fine metal giftware, exceeds international expectations.
Our Six-Layer Quality Assurance Framework is designed to guarantee durability, safety, and consistency — from raw material sourcing to final shipment.
Here’s how we make sure every product that leaves our factory represents the Winko promise: Precision, Reliability, and Trust.
Layer 1: Raw Material Integrity
Every product begins with the right foundation.
We meticulously verify the grade, strength, and safety of each metal — iron sheet, stainless steel, zinc alloy, aluminum alloy — ensuring compliance with RoHS, REACH, and other international standards.
Our QA specialists also perform corrosion and tensile strength tests to confirm performance under varied conditions.
Because quality starts long before production begins.
Layer 2: In-Process Precision
Quality isn’t inspected at the end — it’s built step by step.
Throughout production, our teams check weld strength, dimensional accuracy, plating adhesion, and environmental control.
By monitoring temperature, humidity, and curing conditions, we guarantee every component meets its design intent before moving forward.
Every process, every shift, every batch — verified and recorded.
Layer 3: Final Product Verification
Before any product earns the Winko mark, it faces a series of rigorous performance tests.
These include drop and stress resistance, ASTM scratch testing, UV and humidity durability, and salt spray corrosion tests lasting up to 48 hours.
Only products that achieve a 99.8% pass rate proceed to packaging — a reflection of our dedication to perfection.
Layer 4: Responsible Packaging & Logistics
We believe packaging is part of the product experience.
Our cartons undergo ISTA-standard drop tests, while eco-friendly materials certified by FSC ensure sustainability.
Each shipment is fully documented, labeled, and cleared for international transport — so our partners can trust not only what’s inside the box, but also how it gets there.
Layer 5: Supplier Accountability
Excellence depends on collaboration.
That’s why we conduct annual supplier audits, review third-party lab reports, and verify compliance certifications.
Every supplier is held to the same high standards as our internal teams — because consistency across the supply chain means confidence for our clients.
Layer 6: Continuous Improvement
Quality isn’t static — it evolves.
Our QA team maintains detailed non-conformance logs, performance KPIs, and training programs to ensure continuous improvement.
With digital QA documentation and real-time reporting, we stay audit-ready and transparent with every client.
Excellence by Design
Each product that carries the Winko name represents more than six decades of craftsmanship and innovation.
By integrating science, skill, and accountability, we transform manufacturing into a promise — a promise of quality that our global partners can measure, trust, and rely on.
