Since our inception as Tiezhu Hardware Factory in 2007, Ningbo Huazhu Precision Machinery Co., Ltd. has redefined the standards of Zinc Alloy Die Casting Bulk Manufacturing. Rebranded in 2015 to align with our technological pivot toward Industry 4.0, we have grown from a local workshop into a 20,000 m² global manufacturing powerhouse. Zinc alloy die casting is no longer just about volume; it is about "Precision Engineering" where tolerances are measured in microns and surface finishes compete with high-end jewellery.
Our philosophy is simple: "To create value for customers, achieve win-win partnerships, and empower employees." This core belief drives our integrated R&D, ensuring that every bracket, handle, and hinge leaving our facility is a testament to Chinese manufacturing excellence.
Leveraging "Smart Manufacturing" to de-risk global hardware procurement.
We manage the entire industrial chain: Mold making (28-35 days), die-casting, precision machining, polishing, and PVD coating. This eliminates 3rd-party delays and ensures 100% quality traceablity.
Our engineers utilize hot and cold chamber die-casting machines with 0.02mm processing accuracy. We provide complex solutions for Zinc, Aluminum, and Stainless Steel components.
Serving world-renowned brands like Dornbracht (Germany), TOTO (Japan), and ROCA (Spain), we understand the stringent requirements of international E-E-A-T standards.
Transitioning beyond standard Zamak 3 to Zamak 5 and Zamak 8 for high-tensile strength applications in automotive and smart lock industries.
Reducing material weight by 20% while maintaining structural integrity, ideal for modern minimalist architectural hardware.
Replacing traditional chrome with Eco-friendly PVD (Physical Vapor Deposition) and powder coating solutions that meet REACH and RoHS compliance.
Using AI-simulated mold flow analysis to predict defects before the first drop of molten alloy enters the cavity, reducing waste and lead times.
Navigating the complex landscape of global standards (IATF 16949 & ISO 9001).
