Designed for elite architectural projects and high-humidity environments requiring extreme corrosion resistance.
Ningbo Huazhu Precision Machinery Co., Ltd. (formerly Tiezhu Hardware Factory) was established in 2007 and rebranded in 2015. Over years of dedicated development, we have grown into a full-service manufacturing enterprise, integrating R&D, production, and sales to deliver high-quality hardware solutions.
Specializing in bathroom hardware, shower room accessories (e.g., shower hinges), faucets, door/window hardware, and furniture hardware, we serve domestic and international clients with precision-engineered products, earning consistent customer acclaim. Committed to innovation and quality, we provide custom technical solutions for precision hardware across industries.
"To create value for customers, achieve win-win partnerships, and empower employees to realize their potential."
Understanding local geographic challenges and commercial opportunities in the Indian Ocean marine ecosystem.
Takamaka (located on the southern coast of Mahé, Seychelles) experiences high ambient humidity, elevated levels of airborne marine salts, and intense UV exposure. Standard hardware degrades within 6–12 months, making coastal-grade architectural fittings absolute necessities.
Luxury resorts and boutique eco-lodges demand lead-free, non-toxic, and long-lasting metals that comply with regional environmental guidelines. Sustainable building certifications require raw material audits and energy-efficient lifecycle assessments.
As an island destination, shipping and custom clearance delays put construction timelines at risk. Sourcing from a vertically integrated manufacturer with guaranteed lead times and comprehensive quality checks mitigates logistical vulnerabilities.
In structural project sites along coastal zones like Takamaka, architectural metals face severe atmospheric corrosion classified under the C5-M (Marine) ISO 12944 standard. Traditional zinc die-cast parts quickly develop white rust, and sub-standard stainless steels experience micro-pitting. To solve this, our technical department has optimized the alloy chemistry and electroplating parameters for all products destined for the Indian Ocean market.
Our sanitary and door hardware parts are tested under continuous saline fog according to the ASTM B117 standard. While standard industry fittings achieve a neutral salt spray (NSS) rating of 24 to 48 hours, our premium solutions easily exceed 240 hours, with options for extreme marine applications extending up to 480 hours without substrate oxidation.
Pioneering materials science and surface treatment technologies to deliver long-lasting durability.
We utilize premium-grade Zamak-3 and Zamak-5 zinc alloys alongside high-grade aluminum. Our temperature-controlled hot and cold chamber die-casting machines apply high clamping pressures to eliminate micro-porosities, creating structurally sound parts that withstand heavy daily use.
By implementing Physical Vapor Deposition (PVD), we deposit thin, durable ceramic films over nickel-chrome substrates. This process yields brilliant metallic finishes (brushed gold, matte black, oil-rubbed bronze) that resist scratches, saline air, and cleaning chemicals.
Aligned with global smart hospitality trends, our engineering department integrates IoT components, electronic RFID locking mechanisms, and automated water-saving sensors directly into traditional casting designs.
Equipped with high-performance CNC centers, we achieve processing tolerances down to 0.02 mm. This guarantees smooth pivot movement, consistent spring tension, and uniform water flow rates across all bathroom components.
Ningbo Huazhu Precision Machinery Co., Ltd. operates a fully integrated vertical production chain. Unlike brokers who outsource key manufacturing steps, we control every phase of production inside our 20,000 square meter facility.
Our company has successfully obtained the ISO 9001:2015 Quality Management System Certification and operates in alignment with IATF 16949 automotive-grade quality standards. This rigorous framework ensures complete traceability of raw material heats, strict operational control, and consistent quality parameters across every production batch.
We continually provide OEM/ODM manufacturing services to several premium hardware brands globally, adjusting testing profiles to meet European CE, German DVGW, and US ASME requirements. Sourcing from our facility ensures your project receives fully certified materials.
Request Quality ReportsTailored structural configurations designed to meet B2B commercial, hospitality, and residential project requirements.
For large-scale hotels and high-end residential builds in island regions, we configure complete, integrated packages of matching brass, zinc alloy, and stainless steel hardware—including frameless glass clamps, custom faucets, and bathroom accessories—finished in high-durability PVD.
We collaborate directly with architectural firms and brand product managers to convert custom CAD drafts into high-performing cast hardware. Our engineering team refines geometries to optimize metal flow, ensuring mechanical strength and cost-effective manufacturing.
Engineered for high-traffic environments, our heavy-duty sliding glass door knobs, hinges, and lock sets undergo testing beyond 200,000 opening cycles to ensure reliable functionality and long-term performance.
We operate a dedicated tooling workshop, which allows us to accelerate prototyping timelines and maintain tight manufacturing schedules. Our production facility is equipped with hot and cold chamber die-casting systems, multi-axis CNC machines, and high-capacity polishing stations, allowing us to handle high-volume production orders.
By integrating advanced casting, machining, and surface-finishing technologies, we deliver custom fittings that meet precise structural specifications.

Establishing clear, efficient project milestones from first design files to final ocean freight delivery.
Our engineering department evaluates your CAD drawings (STEP/IGS/DWG format) and optimizes wall thicknesses, gating channels, and shrinkage rates for die casting.
Tooling is manufactured using precision EDM machinery. Tooling is completed within 28-35 days, followed by sample production and submission for client review.
Upon sample approval, mass production begins using automated hot/cold die-casting, mechanical deburring, precision machining, and plating or PVD coating.
Every batch undergoes salt spray, thickness, and functional testing. Products are packaged in protective boxes and shipped through Ningbo Port to global destinations.
Partnering with leading international brands to deliver premium architectural solutions.
Answers to technical, logistical, and structural questions from project managers and procurement specialists.
We use high-purity Zamak alloys and marine-grade stainless steels. Parts undergo automated polishing to remove micro-crevices, followed by multi-layer electroplating or PVD. Our marine-finished items pass 240-to-480-hour neutral salt spray tests, offering long-term protection against airborne ocean salts.
Standard tooling development ranges from 28 to 35 days, depending on geometry complexity. This window includes mold flow analysis, tool machining, and casting initial samples. Once samples are approved, bulk production takes approximately 30 days.
Yes. Our factory operates under ISO 9001:2015 quality management systems. We regularly supply international brands with components that pass certification for CE, EN, and ASME standards. We provide chemical composition certificates and load testing data for every batch.
By managing mold making, casting, CNC machining, polishing, electroplating, and testing in-house, we eliminate outsourcing markups and reduce transit delays. This integrated production gives us full quality control, resulting in lower defect rates and predictable delivery times.
We offer a wide range of surface finishes, including bright chrome, satin nickel, matte black, powder coating in any RAL code, and advanced PVD finishes (brushed brass, copper, and gunmetal).
