“Hardware craftsmen travel everywhere; no county is without Kang.” The old saying about Yongkang’s itinerant smiths is centuries old, but the modern version is more striking: this county-level city in central Zhejiang—China’s Hardware Capital (中国五金之都)—makes the flask on your desk, the door on your apartment, and possibly the drill in your garage, even though you’ve never heard its name.
The Numbers Behind the Titles
Yongkang holds a stack of official titles—Hardware Capital, Cup & Flask Capital (中国口杯之都, awarded 2010), Door Capital, Power Tool Capital. The data justifies each one:
- Vacuum flasks: The cluster accounts for roughly 60% of China’s flask output value and over 80% of its exports, producing ~600 million flasks a year—widely reported as one in three vacuum flasks in the world. Listed company Hals (哈尔斯) anchors the brand tier, while hundreds of OEM factories serve global brands.
- Security doors: About 70% of China’s production, plus a full door hardware chain.
- Power tools: Roughly half of China’s output—local framing claims “five of every ten sets of power tools globally.”
- Overall scale: The hardware industry surpassed ¥100 billion in annual output value in 2024, with exports above ¥38 billion, and the city’s above-designated-size industrial output reached ¥108.9 billion in 2025.
The 1-Hour Industry Circle
Yongkang’s edge is hyper-local density. Local industry coverage describes an “hour industry circle”: within a one-hour drive you can source every input a hardware product needs—stainless steel strip, molds, plastic injection, surface treatment, packaging. Local suppliers claim an 80%+ local parts rate, which is why a custom flask with new printing can sample in 72 hours and a door hardware set in days.
Logistics complete the picture: since 2021, sea-rail intermodal trains run directly from Yongkang East station to the ports of Ningbo-Zhoushan and Wenzhou, putting this landlocked county on container schedules competitive with coastal cities.
What Global Buyers Source Here
- Vacuum flasks and bottles: The flagship category—from commodity steel flasks to pure-titanium premium lines that have become a fast-growing segment.
- Cookware: The cluster’s cookware sector (part of its “kitchenware capital” framing) supplies stainless steel pots, pans, and utensils at OEM scale.
- Doors and building hardware: Export-strong into Southeast Asia, the Middle East, and Africa’s construction booms.
- Power tools and garden equipment: The value tier, with digital workshops increasingly the norm.
Sourcing Playbook
- Flask buyers: specify the steel and the vacuum standard. 304 vs 316L inner walls, copper-plated or not, and vacuum retention test duration (6h/12h/24h at stated temperatures). Yongkang factories test routinely—demand the data.
- Mind the tier gap. With 2,000+ flask-related businesses alone, quality spread is enormous. Filter by export track record and testing equipment on site (vacuum testers, salt-spray chambers).
- Doors and tools: audit welding and motor lines. These are the two processes where mid-tier factories cut corners visibly.
