Established in 2007 (formerly known as Tiezhu Hardware Factory) and rebranded in 2015, Ningbo Huazhu Precision Machinery Co., Ltd. has evolved into a premier full-service manufacturing enterprise. We integrate advanced R&D, precision production, and global sales to deliver high-quality hardware solutions.
We specialize in producing high-end shower enclosure accessories, bathroom fittings, door and window fittings, and custom furniture hardware. Our vertical integration spans the entire industrial chain: mold making, die-casting, machining, polishing, electroplating, inspection, assembly, and packing.
"To create value for customers, achieve win-win partnerships, and empower employees to realize their potential."
Why global industry leaders choose Ningbo, China as their primary manufacturing hub for high-precision furniture hinges and architectural fittings.
Unlike factories that outsource critical steps, we manage the entire production cycle in-house. From raw zinc/aluminum alloy die-casting to advanced PVD plating and final assembly, this ensures absolute quality control and shorter lead times.
With an in-house mold development workshop and engineering team, we reduce mold opening times to just 28-35 days. This allows global furniture brands to accelerate their time-to-market for custom hardware lines.
Operating under ISO 9001 and IATF 16949 quality systems, we offer 100% quality assurance. Our products undergo rigorous testing, achieving up to 480 hours in neutral salt spray tests to withstand high-humidity environments.
Modern interior design demands silent, seamless movement. The industry is rapidly shifting toward integrated hydraulic dampers and soft-close mechanisms. These technologies prevent slamming, reduce wear and tear on wooden cabinetry, and provide a premium tactile experience for end-users.
Physical Vapor Deposition (PVD) has become the gold standard for surface finishing. It offers superior resistance to scratches, fading, and chemical corrosion compared to traditional lacquering. Our factory provides custom PVD finishes in brushed gold, matte black, and gunmetal gray to meet contemporary design aesthetics.
Selecting the right material is crucial for load-bearing capacity and longevity. Zinc alloy (Zamak) is highly favored for complex, decorative hinge designs due to its excellent fluid castability. For heavy-duty or wet environments, stainless steel (SUS304/316) offers unmatched tensile strength and rust resistance.
Environmental compliance is no longer optional. Global buyers require hardware manufactured under strict eco-friendly regulations. Ningbo Huazhu utilizes energy-efficient die-casting machinery and closed-loop water treatment systems in our electroplating lines to minimize environmental impact.
Our custom OEM hinges and hardware components are engineered to perform flawlessly across diverse residential and commercial environments.
High-cycle concealed hinges designed for heavy cabinet doors. Featuring integrated soft-close dampers that resist grease and temperature fluctuations in busy residential kitchens.
Corrosion-resistant glass clamps, shower hinges, and robe hooks engineered from premium zinc alloy and SUS304. Tested to withstand continuous moisture and steam without tarnishing.
Heavy-duty pivot hinges and door handles designed for high-traffic office doors and glass partitions. Engineered for durability, safety, and modern minimalist aesthetics.
Our factory is equipped with state-of-the-art hot and cold chamber die-casting machines, high-precision CNC machining centers, and automated polishing systems. Our processing accuracy reaches an impressive 0.02mm, ensuring perfect alignment and smooth operation for every hinge we manufacture.
To guarantee surface quality, we employ a large team of professional polishing technicians alongside automatic polishing lines. This allows us to achieve flawless mirror finishes, brushed textures, and uniform electroplating layers.
Over the past 18 years, we have proudly provided OEM/ODM services to some of the world's most prestigious sanitaryware and hardware brands, including Germany Dornbracht, Japan TOTO, Italy INDA, and Spain ROCA.
