Ningbo Huazhu Precision Machinery Co., Ltd. (formerly Tiezhu Hardware Factory) is a premier full-service manufacturing enterprise specializing in high-end bathroom hardware. With over 18 years of expertise, we offer an integrated industrial chain: from mold making and die-casting to precision machining, polishing, and advanced electroplating.
Our commitment to excellence is backed by ISO9001 and IATF 16949 certifications, enabling us to serve global leaders like Dornbracht, TOTO, INDA, and ROCA with uncompromising quality and innovative OEM/ODM technical solutions.
In the current global landscape, the resilience of the supply chain is paramount. Ningbo Huazhu operates a fully vertically integrated facility. Unlike competitors who outsource surface treatments or die-casting, our 20,000m² plant controls the entire lifecycle. This eliminates "quality fragmentation" and drastically reduces lead times.
Shower hardware requirements vary significantly by region. For the North American market, there is a dominant trend toward heavy-duty, frameless glass hinges and minimalist "industrial-chic" matte black finishes. Conversely, the European market demands high-compliance PVD finishes and anti-limescale coatings that meet strict environmental standards.
Huazhu supports localization by providing hardware that passes rigorous Neutral Salt Spray (NSS) testing ranging from 240 hours up to 480 hours, ensuring durability in coastal or high-humidity tropical environments.
We are moving beyond standard electroplating. Our technical roadmap includes:
Equipped with state-of-the-art hot and cold chamber die-casting units for Zinc, Aluminum, and Copper alloys.
Utilizing both robotic and manual polishing to ensure mirror-finish quality for luxury bathroom series.
Complete lines for electroplating, powder coating, PVD, and spraying technology for high-end aesthetics.
A: High-grade Zinc Alloy (Zamak 3 or 5) and Stainless Steel (SS304 or SS316) are industry standards. Zinc alloy allows for complex decorative designs and excellent plating adhesion, while stainless steel provides maximum structural integrity for heavy frameless glass doors.
A: We employ a multi-layer electroplating process and offer PVD coatings. Our products are tested in Neutral Salt Spray (NSS) chambers, typically exceeding 240 hours of resistance, which far outlasts standard consumer-grade hardware.
A: Yes. We have a dedicated mold workshop. We can take a client's 3D drawing or sample and provide a prototype within 28-35 days. We also offer laser engraving for custom brand logos.
A: Ningbo is a world-renowned hub for precision machinery and bathroom hardware. This location provides us with access to a highly skilled labor pool, specialized raw material suppliers, and one of the world's busiest ports (Ningbo-Zhoushan), ensuring efficient logistics and competitive pricing.
