Established in 2007, Ningbo Huazhu Precision Machinery Co., Ltd. (formerly Tiezhu Hardware Factory) has evolved into a global titan in the field of precision bathroom fittings and custom hardware. With a sprawling 20,000 m² facility, we integrate the entire industrial chain—from mold making and die-casting to electroplating and PVD coating.
Our philosophy is built on three pillars: "To create value for customers, achieve win-win partnerships, and empower employees." This commitment has allowed us to serve world-renowned brands such as Germany's Dornbracht, Japan's TOTO, Italy's INDA, and Spain's ROCA.
The global bathroom fittings market is undergoing a seismic shift. Today’s procurement managers at top-tier architectural firms and hospitality groups aren't just looking for "suppliers"—they are seeking strategic manufacturing partners. In the post-pandemic era, supply chain resilience, material traceability, and sustainability have become non-negotiable requirements.
Leveraging Zamak 3, Zamak 5, and SUS 304/316 alloys to ensure zero-corrosion performance in 100% humidity environments.
Focusing on eco-friendly electroplating and high-durability finishes that extend product lifecycle and reduce environmental impact.
Smart bathroom components including IoT-ready faucets and sensors are the new frontier for high-end developments.
Our technical route is defined by extreme precision. Utilizing cold and hot chamber die-casting machines, we achieve tolerances within 0.02mm. Our surface treatment capabilities are unmatched in the industry:
For international exporters and distributors, navigating compliance can be a hurdle. Huazhu simplifies this through rigorous certification adherence. Holding ISO 9001 and IATF 16949, we ensure our products meet the technical requirements of the European (CE), North American (CUPC), and Japanese (JIS) markets. Our local support includes dedicated account managers who understand the regional nuances of bathroom hardware standards.
Experience, Expertise, Authoritativeness, and Trustworthiness in every component.

Technical Compliance
A: For new mold development, it typically takes 28-35 days. Once molds are finalized, production cycles range from 30 to 45 days depending on the complexity of the surface treatment (e.g., PVD requires specialized scheduling).
A: We utilize advanced spectrophotometers and maintain strict control over our electroplating bath chemistry. Each batch is compared against a "Golden Sample" to ensure ΔE (color difference) remains within strict client tolerances.
A: Yes, while we are a high-capacity factory, we offer flexible production lines to accommodate high-value boutique projects that require bespoke finishes or unique handle designs.
A: Absolutely. All our bathroom fittings can be tested in-house or through SGS/TÜV to verify 240H to 480H Neutral Salt Spray (NSS) performance.
