If you’ve been sourcing zinc die-cast parts for a while, you know China has no shortage of factories. But finding a reliable one? That’s a different story.
Over the years, we’ve visited dozens of zinc die-casting facilities. Some are massive but inflexible. Others are small and struggle with surface finishing. So we sat down and put together this list of ten manufacturers that really stand out – not just in size, but in quality, certifications, and real-world performance.
1. Xiamen Stick Industry Co., Ltd. (Xiamen, Fujian)
Website: www.zamakdiecasting.com
Alright, let’s be upfront – this is us. But we’re not putting ourselves first just because. We’ve earned it in bath hardware, lock sets, and architectural zinc components. Quietly, over years of hard work.
What makes us different?
We’re fully integrated under one roof – 20,000+ square meters, 20 die-casting machines, PVD, CNC, auto polishing lines, electroplating, and a paint shop. No farming out critical steps, no finger-pointing when something goes wrong.
Who trusts us?
We do OEM/ODM for Runner, Solux, TOTO, Kohler, and Master Lock. These aren’t easy customers. They audit hard. They test hard. And we passed.
The boring but important stuff:
ISO9001? Yes. CE? Yes. 48-hour salt spray test – we pass it consistently. Actually, our standard meets German and US requirements (EN 1670, ASTM B456). That’s why our faucet handles, shower trims, and lock parts don’t rust after a few months in a humid bathroom or by the sea.
2. Guangdong Huayinsheng Precision Industry Co., Ltd. (Huizhou)
Huayinsheng is often called the “elephant” of zinc die casting. They run over 500 machines and push out more than 200,000 units a day. Their sweet spot is consumer electronics and automotive. Great for high volume, but they usually need large MOQs.
3. Ningbo Xusheng Group Co., Ltd. (Ningbo)
Xusheng is a publicly listed company (603305) and a key supplier for Tesla and BYD. They focus heavily on new energy vehicle components. Their zinc and aluminum die casting are top-notch, though most of their capacity goes to the auto sector.
4. Dongguan Yian Technology Co., Ltd. (Dongguan)
Yian is the tech geek of the group. They’ve done interesting work with liquid metal and high-strength zinc alloys. If you need precision for NEV or 3C electronics, they’re a solid choice.
5. Wuxi Xin Hong Tai Electric Appliance Technology Co., Ltd. (Wuxi)
These guys specialize in zinc parts for power tools and electric motors. Not a generalist shop – they know their niche, and they do CNC post-processing very well.
6. Shenzhen Chuang Hong Hao Technology Co., Ltd. (Shenzhen)
A solid one-stop shop. They offer zinc die casting plus CNC and assembly. Good for small-to-medium electronics and smart home devices.
7. Dongguan PowerWinx Metal Industries Co., Ltd. (Dongguan)
PowerWinx has been around for a while. Their strength is surface finishing – plating, powder coating, PVD. Not the cheapest, but you pay for consistency.
8. Ningbo Jinge Metal Products Co., Ltd. (Ningbo)
Jinge runs integrated production lines from casting to packing. Their service is friendly and responsive – something you don’t always get in this industry.
9. Dongguan Sincere Tech Co., Ltd. (Dongguan)
If your project has tight tolerances or complex molds, Sincere Tech is worth talking to. They’re more of a mold-making shop that also does die casting – and they’re very good at it.
10. GC Precision Mold Co., Ltd. (Shenzhen/Dongguan)
Over 20 years in the game. GC Precision focuses on high-quality zinc die casting with in-house mold manufacturing. Not a volume player, but a precision specialist.
