The global heavy machinery, metallurgical equipment, and crushing industries demand component structures that can withstand extreme mechanical loads, thermal fatigue, and corrosive environments. As a leading force among modern foundry manufacturers in China, Henan Hanhai Metallurgy Mining International Trade Co., LTD (widely known as Hanhai Casting) has established a deep integration of scientific design, advanced materials technology, and large-scale manufacturing workflows. Specializing in high-performance cast steel and cast iron components, our annual output of 80,000 tons reflects our engineering capacity and commitment to absolute precision.
Modern foundry manufacturing has evolved past traditional sand molding into a data-driven, highly digitalized discipline. From finite element analysis (FEA) optimization of large valve bodies to the strict crystallization controls of heavy machinery components, our infrastructure is designed to deliver reliability. Certified with both ISO9001:2015 and CE marking, Hanhai Casting products serve key projects across Asia, the Middle East, Europe, and South America, supporting operations in mining processing, power generation, maritime engineering, and industrial infrastructure.
Hanhai Casting was established with a focus on heavy steel and iron castings, laying a solid technical and production foundation by investing in initial arc furnaces and large sand casting pits.
Introduced advanced melting, chemical composition validation (Optical Emission Spectrometry), and computerized molding technology. We expanded production capacity to serve large mining and metallurgical sectors domestically.
Achieved ISO9001 certification and upgraded our non-destructive testing (NDT) systems. Hanhai expanded international exports, shipping custom industrial machinery end caps and turbine housings to Asia and the Middle East.
Integrated intelligent foundry systems and digital management software (MES/ERP), driving sustainable manufacturing protocols, automated temperature control, and global customer partnerships.
The transition of heavy casting from a labor-intensive industry to a high-precision, low-carbon engineering discipline is driven by technological advancements. Our roadmap focuses on integrating digital tooling, advanced simulation software, and automation to eliminate dimensional discrepancies and sub-surface defects before pouring begins.
By using MAGMAsoft solidification simulation, our engineering team maps velocity fields, temperature distribution, and cooling behaviors. This eliminates shrinkage, gas porosity, and hot tearing before the molds are constructed.
By introducing 3D sand printing (binder jetting) for complex core geometries, we bypass traditional wooden tooling patterns for complex turbine cylinders and industrial valves, shortening prototype cycles by up to 60%.
Our long-term environmental target aligns with national carbon reduction goals. We deploy thermal sand reclamation systems to reuse up to 95% of silica sand and capture waste heat from coreless induction furnaces.
Hanhai Casting delivers engineered products across five industrial pillars, ensuring high durability under dynamic loads.
Heavy wear demands high toughness. We cast high-manganese steel and chromium alloys for jaw plates, support sleeves, and PY cone crushers. This maximizes wear resistance and operational lifespan in tough mining conditions.
Large rotary kilns and ball mills rely on custom girth gears, support rollers, and hollow shafts. Hanhai Castings supplies sound steel components designed to handle high mechanical stress and resist surface spalling.
Our casting line produces large high-pressure valve bodies and turbine cylinders. Using computer-controlled gas pouring systems, we secure uniform wall thicknesses that withstand intense pressure testing.
Operating from China's industrial heartland, Hanhai Casting leverages a mature supply chain. Our strategic location near raw alloy suppliers, specialized tooling workshops, and heavy transport networks allows us to control costs and maintain stable lead times. This structural efficiency is critical for maintaining an annual capacity of 80,000 tons.
By integrating ERP systems with real-time furnace monitoring, we track chemical and physical properties throughout production. This ensures tracing from initial raw charge loading to final stress-relieving heat treatment. Through this system, global buyers receive clear milestone visibility and reliable delivery schedules.
Direct partnerships with domestic alloy suppliers guarantee a steady supply of chromium, manganese, nickel, and molybdenum. This insulates our manufacturing timeline from raw material price volatility.
We provide both rough cast castings and high-precision CNC machining. Our vertical boring mills, double-housing planers, and heavy lathe equipment ensure parts are delivered to exact print specifications.
Close proximity to inland logistics nodes and international shipping ports like Qingdao and Tianjin guarantees reliable containerized cargo shipping and break-bulk logistics for oversized castings.
We focus on maximizing operational wear life to reduce long-term maintenance costs. Our design optimizations reduce weight without sacrificing strength, which minimizes shipping costs and material usage.
Every casting batch is shipped with mill test certificates (EN 10204 3.1 or 3.2), chemical composition analyses, mechanical testing reports (tensile, yield, charpy-V notch impact), and NDT reports.
We function as an extension of your engineering department. Our specialists assist in redesigning cast configurations, optimizing draft angles, and proposing metallurgical modifications for specific field environments.
Gather design specifications, operating environments, loading profiles, and regulatory compliance standards.
Simulate filling behavior and cooling kinetics to design riser placements, gating networks, and chill sizes.
Finalize drawing tolerances, heat treatment requirements, and non-destructive testing plans.
Execute pattern creation, sand molding, furnace melting, pouring, and controlled cooling stages.
Perform UT/MT inspections, chemical analyses, and dimensional verification on coordinate measuring machines.
Package components in ocean-safe packaging and coordinate delivery through ocean or overland freight corridors.
Every casting run from Hanhai undergoes rigorous verification. Our ISO 9001 and CE credentials show our adherence to international quality protocols. Our internal laboratory is equipped with mechanical testers, impact energy machines, carbon-sulfur determiners, and ultrasonic detectors. This allows us to verify that all physical properties match standard ASTM, DIN, BS, or JIS requirements before shipment.
