Ningbo Huazhu Precision Machinery Co., Ltd. (formerly Tiezhu Hardware Factory) is more than a supplier; we are an integrated R&D powerhouse.
Established in 2007, Ningbo Huazhu Precision Machinery Co., Ltd. has evolved into a full-service manufacturing enterprise. We specialize in producing high-end shower enclosure accessories, bathroom fittings, and door/window hardware. By integrating the entire industrial chain—from mold making and die-casting to precision machining, electroplating, and final assembly—we offer a seamless OEM experience for global market leaders. Our philosophy is rooted in creating value for customers, achieving win-win partnerships, and empowering our workforce to reach their full potential.
Driving the future of bathroom hardware with advanced materials and smart manufacturing.
At the core of every premium faucet component is the integrity of the casting. We utilize advanced hot and cold chamber die-casting machines that allow for tolerances as tight as 0.02mm. This precision ensures that faucet bodies and handles not only look perfect but maintain structural integrity under high water pressure. Our expertise in zinc alloy (Zamak) provides a cost-effective yet durable alternative to traditional brass, without compromising on the luxurious "heavy" feel consumers expect.
In the modern bathroom, finish is everything. Our in-house surface treatment facility offers a spectrum of options including Chrome, Brushed Gold, Matte Black, and Physical Vapor Deposition (PVD). PVD coatings provide a molecular bond that is virtually impossible to scratch or tarnish. For OEM clients, we guarantee salt spray testing performance from neutral 240H up to 480H, meeting the most stringent international standards for corrosion resistance.
The roadmap for 2025 and beyond is focused on sustainability. Our R&D team is working on integrating low-flow aerators and ceramic disc valve components that exceed LEED and WaterSense requirements. We assist our partners in developing "Eco-Friendly" product lines that reduce water consumption by up to 30% without sacrificing user experience.
Our dedicated mold workshop reduces development lead times to just 28-35 days, allowing brands to launch products faster.
100% inspection protocol. Certified under ISO 9001 and IATF 16949 for automotive-grade precision in bathroom hardware.
Trusted by industry giants such as Dornbracht (Germany), TOTO (Japan), INDA (Italy), and ROCA (Spain).
How we leverage automation and localization to guarantee supply chain stability.
The global procurement landscape has shifted towards a need for "supply chain resilience." Ningbo Huazhu addresses this by localizing the entire production cycle within our 20,000 sqm facility. By controlling everything from the raw material alloy to the final PVD coating, we eliminate the risks associated with multi-vendor outsourcing.
We don't just sell parts; we provide solutions for diverse sectors:
Hot & Cold chamber machines for diverse alloy types.
Multi-axis precision for complex internal geometries.
Robotic arms ensure consistent mirror-finish quality.
Spectrum analyzers and 3D coordinate measuring machines.
Meeting global standards for every market.
Navigating the regulatory requirements of different countries can be a hurdle for many brands. Huazhu provides comprehensive support to ensure our OEM components meet localized standards such as WRAS (UK), NSF/ANSI 61 (USA), and CE (Europe). Our IATF 16949 certification is a testament to our ability to maintain rigorous quality control usually reserved for the automotive industry, ensuring that every faucet handle or valve body is built to last a lifetime.
Expert insights into faucet component manufacturing and procurement.
We primarily use high-grade Zinc Alloy (Zamak) and Brass. Zinc is excellent for complex designs and cost-efficiency, while brass offers traditional durability and weight.
For custom OEM faucet components, our mold development cycle is typically 28 to 35 days from technical drawing approval.
Yes, we offer Physical Vapor Deposition (PVD) in various colors including Gold, Rose Gold, Nickel, and Champagne, providing superior hardness and corrosion resistance.
While we specialize in high-volume OEM production, we have dedicated lines to support strategic brand launches and mid-sized orders.
We conduct in-house salt spray testing. Depending on customer requirements, we can achieve up to 480 hours of neutral salt spray resistance.
Absolutely. We strictly adhere to international lead-free regulations to ensure safety and compliance with drinking water standards.
