Explore our foundational structural closures, certified to meet international tensile and environmental requirements.
Elevating functional trim details to pillars of hardware engineering and structural integrity.
In modern performance apparel, tactical gear, and luxury outerwear, cord locks are not merely secondary fastening choices. They are critical interfaces engineered to retain structural tightness, ensure user safety, and match overall brand values. As a leading ODM Metal Cord Locks Company and Exporter, Wenzhou Fangyuan Metal Button Co., Ltd. (established in 1995) addresses these structural needs through material innovation, structural design, and absolute compliance certifications.
Choosing to use metal cord locks instead of plastic alternatives is a strategic decision. Metal options deliver high pull strength, excellent corrosion resistance under harsh conditions, and premium tactile feedback. From securing adjustments on high-altitude alpine jackets to maintaining closure tension on tactical packs, metal cord locks serve as reliable hardware points that protect brand reputation and satisfy end-users.
"Value creation in global component procurement requires more than just meeting a low unit price. Real value is established by working with certified manufacturing facilities that provide complete chemical compliance, trace their raw material supply chains, and guarantee mechanical consistency across millions of units."
— Wenzhou Fangyuan Quality Assurance BoardDeveloping custom hardware that outperforms plastic alternatives in durability, tensile strength, and cycle lifespan.
Our zinc alloys offer excellent fluid mobility, allowing us to mold complex, thin-walled shapes. This results in precise brand engraving, crisp structural edges, and uniform wall thickness across all production batches.
Perfect for marine and outdoor applications. Our brass components are naturally rust-resistant and non-magnetic. They provide reliable protection against saltwater corrosion and harsh outdoor exposure.
The performance of a cord lock depends directly on its internal spring. We use SUS 302 and SUS 304 stainless steel springs, calibrated to sustain continuous compression cycles without fatigue.
Our technical team subjects all cord lock assemblies to strict laboratory testing. Below are the key engineering metrics used during our quality assurance processes:
| Test Parameter | Standard Testing Protocol | Target Performance Level | Target Application Segment |
|---|---|---|---|
| Static Cord Gripping Retention | ISO 13935 / ASTM D5034 modification | ≥ 45 N (Newton force under load) | Military Tactical Outfitting & Harnesses |
| Salt Spray Corrosion Test | ASTM B117 / ISO 9227 (Neutral Salt Spray) | Up to 96 hours without red/white rust | Marine Apparel & Commercial Fishing Gear |
| Spring Compression Fatigue | In-house cycle fixture compression testing | ≥ 10,000 cycles with < 5% loss in force | Heavy-use Outerwear & Backpack Drawstrings |
| Nickel and Lead Release | EN 1811 (European Standard) / CPSIA Section 101 | Below detection limits / Lead < 90 ppm | Certified Children's Apparel & Next-to-skin Wear |
Addressing international regulatory requirements through local compliance strategies.
Operating a global apparel brand requires navigating a complex environment of international trade rules and product safety regulations. Wenzhou Fangyuan provides customized support to make international sourcing straightforward and compliant. Whether you need to meet European REACH regulations, US CPSIA guidelines, or California Proposition 65 requirements, we back every shipment with testing documents and raw material certifications.
Our facility holds ISO9001:2008 and ISO14001:2004 environmental certifications. We are also authorized to supply components compliant with the European Union's environmental safety label, Oeko-Tex Standard 100. This ensures that every metal button, eyelet, snap, and custom metal cord lock we produce is safe for consumer contact and free from harmful chemicals.
High capacity and material control from China's primary hardware production base.
Located in Qiaotou, Wenzhou—often recognized as a key center for button and garment accessory manufacturing in China—our company operates within an efficient industrial ecosystem. This concentration of raw material suppliers, plating specialists, and logistics partners allows us to respond quickly to changing requirements.
With an annual output value exceeding 100 million RMB and self-managed import/export capabilities, we handle everything from tooling design and die-casting to electroplating and testing in-house. This centralized control reduces production lead times and ensures consistent quality control for high-volume orders.
Combining functional drawstrings with a range of specialized metal closures and hardware elements.
A functional drawstring system works best when paired with matching metal components. At Wenzhou Fangyuan, we design and produce coordinating metal buttons, rivets, snap systems, and eyelets. This single-source approach ensures consistent color finishes and matching material performance across all design elements.
Our brass eyelets provide clean reinforcement for fabric exit points. They protect material edges from fraying under cord lock tension, making them ideal for hoodies, jackets, and marine gear.
We supply snap buttons in sizes from 7.5mm up to 21mm in copper, brass, and stainless steel. These fasteners provide complementary quick-closure options alongside drawstring systems.
Constructed from high-grade zinc alloys and brass, our jeans buttons and rivets withstand commercial laundering and heavy wear. They provide reliable, long-lasting performance for denim collections.
Understanding how functional hardware meets the specific design requirements of different apparel segments.
Windbreakers and heavy coats require secure hood and hem adjustments. Our metal cord locks hold drawstrings firmly under cold, windy, and wet conditions, ensuring proper garment performance.
Luggage and backpacks require reliable closures for load stabilization. Our heavy-duty metal cord locks secure pocket openings and cinch straps against continuous wear and tension.
Sweaters and joggers need lightweight, low-profile fasteners. We supply smaller, streamlined cord locks that provide reliable tension control without adding bulk to dynamic activewear.
