Osaka, historically known as the "Manchester of the Orient," remains Japan's critical industrial hub for precision metalwork and bathroom fittings manufacturing. The city’s unique position as a port hub has fostered a centuries-old tradition of copper and alloy craftsmanship. Today, Osaka's industrial zones are synonymous with Monozukuri—the Japanese philosophy of making things with sincerity and continuous improvement.
For global procurement officers, Osaka represents the pinnacle of reliability. The local ecosystem comprises specialized die-casting plants, advanced electroplating facilities, and R&D centers that focus on water-saving technologies and anti-corrosive material science. Our operations, though centered in Ningbo, integrate these rigorous Japanese industrial standards (JIS) to provide export-grade hardware that meets the high expectations of the Kansai commercial market.
Ningbo Huazhu Precision Machinery Co., Ltd. (Formerly Tiezhu Hardware) has evolved since 2007 into a global leader in bathroom hardware. By integrating R&D, mold development, and high-end surface treatment, we deliver solutions that are not just products, but components of architectural art. Our philosophy is simple: "To create value for customers and realize win-win partnerships through precision."
Supplying bulk, durable fittings for hotel chains in Osaka and beyond. Our products withstand high-frequency use while maintaining aesthetic brilliance.
Customizable OEM/ODM designs for luxury condominiums, focusing on "Universal Design" to support Japan’s aging population.
Precision-engineered shower hinges, glass clamps, and connectors for frameless glass door systems.
Our facility is equipped with several hot and cold die-casting machines capable of processing Zinc Alloy and Aluminum. With machining accuracy reaching 0.02mm, we guarantee the mechanical integrity of every hinge and faucet body we export.
The whole industrial chain is under one roof: Mold making -> Die-casting -> Machining -> Polishing -> Electroplating/PVD -> Assembly. This vertically integrated model allows us to shorten development cycles to just 28-35 days.
Transitioning to zero-discharge electroplating lines and expanding PVD color palettes (Brushed Gold, Rose Copper, Matte Black) to meet contemporary design trends.
Developing IoT-enabled bathroom accessories and touchless sensor-integrated faucet handles for the hygiene-conscious post-pandemic market.
Researching lead-free brass and recycled aluminum alloys to support global sustainability and ESG (Environmental, Social, and Governance) targets for our international clients.
Exporting to Japan, Europe, and the USA requires more than just a product; it requires a commitment to safety and regulatory standards.

Automotive-grade Precision Standards
Up to 480H for extreme durability
For standard orders, it takes 15-25 days. For custom mold development and OEM solutions, the process takes 28-35 days from blueprint approval to the first sample.
We use high-grade Zinc Alloy and Stainless Steel with advanced multi-layer electroplating or PVD treatment, ensuring a neutral salt spray test performance of up to 480 hours without corrosion.
Yes, we specialize in supplying lead-free materials to meet stringent California (USA) and European drinking water standards, as well as Japanese JIS requirements.
While we are a production-oriented factory, we have a dedicated "fast-track" line for mold development that allows us to support medium-to-large boutique projects with custom finishes.
