Explore our premium architectural fittings, custom die-cast alloys, and luxury hardware systems manufactured to meet zero-defect tolerances.
In the global market of high-end real estate, luxury hospitality developments, and premium interior design, the importance of architectural hardware has shifted. No longer considered minor functional details, fittings, handles, brackets, and hinges have become central to aesthetic cohesion and tactile user interaction. Today's global enterprises require components engineered with tight dimensional tolerances, exceptional surface finishing, and proven durability to match their high design requirements.
Ningbo Huazhu Precision Machinery Co., Ltd. (formerly Tiezhu Hardware Factory) has positioned itself as an industry leader in this sector. Established in 2007 and rebranded in 2015, the company has integrated advanced raw material formulation, structural die-casting, high-precision machining, and surface treatment technologies to build a complete vertical manufacturing process. Operating a 20,000 m² production facility with over 200 skilled specialists, Huazhu delivers custom OEM/ODM solutions to international brands, ensuring each part aligns with strict quality and functional requirements.
The manufacturing cluster in Ningbo, Zhejiang, provides a competitive mix of supply chain density, raw material access, and advanced engineering capabilities.
Our in-house mold facility shortens development lifecycles. Custom mold fabrication typically takes 28 to 35 days, accelerating the prototyping process and facilitating a faster transition from concept design to mass production.
Our facility manages the entire production cycle under one roof. We oversee raw materials through mold opening, die-casting, mechanical machining, polishing, custom plating, spray coating, powder coating, PVD, and automated inspection.
We perform rigorous salt spray corrosion tests based on customer requirements. Our components demonstrate between 240 and 480 hours of Neutral Salt Spray (NSS) resistance, ensuring longevity in high-moisture environments.

The luxury hardware sector is shifting toward materials and finishes that offer both performance and visual appeal. Current design trends emphasize clean lines, geometric profiles, and surfaces that resist oxidation and wear. Zamak (zinc alloy), aluminum alloy, and premium stainless steel remain the preferred materials for high-end applications due to their structural integrity and design flexibility.
A key market development is the adoption of Physical Vapor Deposition (PVD) coatings over traditional electroplating. PVD processes yield an ultra-hard surface layer that resists scratching, fading, and chemical wear, while presenting finishes like brushed gold, gunmetal, and matte bronze. Additionally, manufacturers are developing ergonomics that support smooth, silent mechanical movement—essential for premium door, window, and cabinet assemblies.
By pairing high-pressure die-casting with precise machining, we produce complex geometries that retain structural strength. This combination of material performance and finishing quality helps global brands meet both aesthetic requirements and demanding durability specifications.
Our facility runs hot and cold chamber die-casting machines coupled with CNC machining centers, allowing us to maintain a processing precision of 0.02 mm. Our machinery handles diverse metals, including zinc alloys, copper, aluminum alloys, and stainless steel castings.
Because surface preparation directly impacts finish quality, we employ automated polishing systems alongside a team of experienced polishing specialists. This combination yields consistent surface smoothness across complex parts, preparing them for electroplating, powder coating, or PVD treatments.
Our quality management is validated by ISO 9001 and IATF 16949 certifications, which govern our workflow from raw materials inspection through final packaging and shipping.
Providing specialized hardware systems that balance mechanical performance with design requirements across different industries.
We provide durable door handles, locks, and wall fixtures for luxury hotels and high-end residential projects, offering unified aesthetics across diverse finishes to meet architectural requirements.
Our 90-degree shower hinges, glass clamps, and support rods are engineered to carry significant glass loads while remaining stable and resistant to moisture and wear.
We manufacture custom window handles and locking gears designed to handle repeating mechanical cycles and weather exposure in residential and commercial settings.
Our production relies on precise machining and systematic inspection to keep dimensions and surfaces uniform. With dedicated mold-making, die-casting, and surface finishing departments, we maintain consistent control over project timelines and quality parameters.
We operate in accordance with ISO 9001 and IATF 16949 standards. This quality management framework covers our entire process, from analyzing raw material compositions to testing functional performance and packaging components for global shipment.
We work as an OEM/ODM partner for several global brands, helping them implement custom design programs.
