Explore our core high-precision components manufactured to 0.02mm tolerances under strict ISO 9001 and IATF 16949 conditions.
Ningbo Huazhu Precision Machinery Co., Ltd. (formerly Tiezhu Hardware Factory) was established in 2007. Over the years, we have transitioned from a localized tooling specialist to a global powerhouse in custom luxury furniture hardware manufacturing.
We boast a vertically integrated production line located in Ningbo, Zhejiang. Our capabilities encompass mold development, high-pressure zinc and aluminum die-casting, CNC precision machining, automated polishing, multi-layer electroplating, and state-of-the-art PVD physical vapor deposition. This complete industrial control allows us to provide reliable OEM/ODM services for many premium global hardware brands.
The global landscape of luxury hardware procurement requires more than basic production capability; it demands absolute supply chain reliability, manufacturing transparency, and technical expertise. At Ningbo Huazhu Precision Machinery, we operate as a fully integrated factory. By managing every stage of production internally, we eliminate third-party delays, guarantee consistent material grade integrity, and ensure complete traceability of all raw materials.
Our core operational workflow starts in our dedicated mold-making workshop. With an in-house engineering team utilizing advanced CAD/CAM software and high-speed CNC centers, we develop production tooling within 28 to 35 days. This enables rapid prototyping and shortens the time-to-market for complex architectural and furniture hardware.
How our custom engineering solves complex physical performance demands across diverse architectural and design verticals.
Designed for 5-star hotels and luxury resorts. Our zinc alloy and stainless steel pull handles, glass clamps, and shower enclosure hinges are built to endure high daily cycle counts. We provide chemical and corrosion resistance to withstand commercial cleaning agents while maintaining aesthetic appeal.
Bespoke interior and exterior hardware that complements luxury residential environments. We work directly with interior designers and architectural joineries to produce cabinet knobs, linear floor drains, and luxury faucets matching specific design languages, finished in PVD brass, matte black, or brushed nickel.
For seaside properties and marine vessels, standard hardware degrades rapidly due to high salinity. We produce hardware from marine-grade SUS316 stainless steel and use high-performance PVD coatings. These undergo strict ASTM B117 salt spray testing for up to 480 hours without pitting or tarnishing.
Enterprise buyers require verifiable quality data. Our quality management system is certified to ISO 9001 and IATF 16949. This automotive-grade certification reflects our strict control over manufacturing consistency, change management, and continuous process optimization.
Every product batch is subjected to comprehensive testing in our quality laboratory. Our quality control team measures dimensional tolerances, checks coating thickness, inspects surface quality, and performs mechanical lifecycle testing to confirm our hardware meets required functional lifetimes.
Innovating the next generation of architectural hardware with eco-friendly methods and smart functionalities.
We are reducing the environmental footprint of our manufacturing. By minimizing heavy metal content, managing zinc and aluminum scrap recycling internally, and optimizing energy usage during melting and casting, we help customers meet green building standards like LEED and BREEAM.
Physical Vapor Deposition (PVD) represents a major advancement in luxury hardware finishing. Applied in high-vacuum chambers, PVD finishes offer excellent hardness and scratch resistance. This process does not produce hazardous chemical waste, making it a sustainable alternative to traditional electroplating.
The rise of home automation requires mechanical systems to interface with smart controls. We are developing cabinetry and entry handles that house biometric sensors, status LEDs, and locking systems, combining luxury aesthetics with modern security technology.
A transparent view into our precision casting, finishing departments, and completed architectural projects.
Managing design complexity and project timelines is a critical challenge in international B2B hardware procurement. We structure our partnerships to minimize risk and simplify custom manufacturing projects.
From initial technical review and CAD optimization to rapid functional prototyping and batch casting, we keep our customers informed with weekly status updates, quality control charts, and shipping tracking. We accommodate custom requirements for packaging, barcoding, and private labeling.
By combining high-precision manufacturing, material expertise, and a vertically integrated production line, we help our partners reduce total cost of ownership and simplify their hardware supply chain.
We provide custom hardware and manufacturing support for brands including Dornbracht (Germany), TOTO (Japan), INDA (Italy), and ROCA (Spain).
Our in-house mold development workshop allows us to offer rapid tooling turnarounds and quickly adapt designs during the R&D phase. This helps minimize project startup delays and reduces total tooling development costs.
With a production line featuring automatic cold and hot die-casting machinery, multi-spindle polishing, and high-capacity plating lines, we maintain production capacity to fulfill both medium and high-volume order requirements.
Huazhu Precision Machinery maintains internationally recognized certifications including ISO 9001 and IATF 16949. These compliance certifications cover our entire engineering pathway from raw material verification to tool design, die-casting, and final inspection.
Engineered options for high-traffic environments and damp commercial locations, including showers, wellness areas, and hotel projects.
