Established in 2007, we deliver end-to-end industrial manufacturing excellence with verified compliance and robust production capabilities.
It was established in 2007, specializes in producing shower enclosure accessories, bathroom fittings, door and window fittings. We have the whole industrial chain of mold making, die-casting, machining, polishing, electroplating, inspecting, assembling and packing. We have successfully obtained the certification of ISO9001, and continually provided OEM service to several famous companies around the world.
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.
Deep technical insights into modern die-casting, material science, and macro-industrial sourcing strategies.
The manufacturing sector of Customize Grip Handlebars and precision hardware is shifting towards micro-tolerance engineering. Leveraging advanced CAD/CAM integration and AI-driven simulation for die-casting molds, we reduce defect rates to near-zero while optimizing wall thickness and structural tensile strength.
Our smart factory ecosystem in Ningbo merges automated robotic polishing with real-time IoT quality checkpoints. This ensures seamless scalability for global enterprises, combining cost efficiency with unmatched delivery punctuality and stringent environmental compliance.
Top international brands across Europe, North America, and Asia demand localized durability standards (such as 480-hour neutral salt spray tests). We provide comprehensive OEM/ODM solutions tailored to architectural hardware and industrial machinery requirements.
