Founded in 2007, Ningbo Huazhu Precision Machinery Co., Ltd. (formerly Tiezhu Hardware Factory) has evolved into a titan of precision manufacturing. Our 20,000 m² facility is the heart of an integrated supply chain—encompassing mold making, die-casting, machining, polishing, electroplating, and assembly.
We provide deep-tier OEM/ODM services for global leaders including Japan's TOTO, Germany's Dornbracht, and Italy's INDA. Our ISO9001 and IATF 16949 certifications are not just badges; they represent our commitment to zero-defect manufacturing in the accessories sector.
The Japanese hardware and accessories market is defined by "Monozukuri"—the art, science, and craft of making things with an unwavering focus on quality. Unlike high-volume markets, Japanese industrial and architectural sectors demand parts that offer extreme durability, precise tolerances (often within 0.02mm), and aesthetic harmony. For bathroom and kitchen fittings, the prevalence of "Unit Baths" (prefabricated bath modules) requires accessories with standardized mounting but premium finishes like PVD and specialized chrome plating.
Globally, the accessories industry is shifting toward "Smart Integrated Hardware." In Japan, this translates to touchless faucet handles and antimicrobial-coated door hardware, accelerated by an aging population that requires "Universal Design" (accessible hardware). As an exporter, we bridge the gap between China's manufacturing scale and Japan's rigorous quality expectations.
Our R&D focuses on three pillars:
Luxury hardware for Japan's booming hotel sector (Tokyo/Osaka). High-durability hinges and decorative plates that withstand high-frequency use while maintaining a 5-star aesthetic.
Modular accessories for the Japanese "Mansion" (apartment) renovation market, focusing on space-saving towel bars and ergonomic cabinet handles.
Precision die-cast components for window systems and door mechanisms, engineered to withstand the seismic and climatic challenges of the Japanese archipelago.
The company covers an area of 20,000 square meters with a group of professional engineers and technicians specializing in mold development, die-casting technology, and high-end surface treatment. Our processing accuracy reaches 0.02mm, ensuring we meet the most stringent specifications from Japanese architectural firms.
Quality Assurance: 100% inspection protocol. We provide salt spray testing from neutral 240H up to 480H depending on client requirements.
Yes. We are experienced in manufacturing zinc and aluminum alloy die-cast parts that comply with JIS H 5301 and JIS H 8641 for surface finishes. Our engineering team can review your technical drawings to ensure full compliance.
Our in-house mold workshop allows us to open new molds within 28-35 days, significantly faster than the industry average, enabling quicker market entry for your new product lines.
Absolutely. We offer PVD coating and trivalent chromium plating, which are more environmentally friendly and comply with RoHS and REACH regulations often required by Japanese importers.
We utilize advanced CNC machining and automated inspection equipment. Every batch undergoes rigorous testing for dimensional accuracy, finish quality, and corrosion resistance.
