Explore our high-performance engineering cast solutions. Strict CE and ISO9001 quality controlled.
In the demanding sector of heavy metallurgy and mineral processing, the components that form the backbone of your operations must embody structural safety, long cycle lifespans, and exceptional thermal fatigue resistance. Henan Hanhai Metallurgy Mining International Trade Co., LTD stands as a premier foundry manufacturer in China. We specialize in producing custom cast steel and cast iron parts, notably heavy industrial components, gear rings, valves, and high-durability steel ingot moulds.
Operating from a state-of-the-art facility, we seamlessly integrate product design, mold casting, heat treatment, and precision machining. Our total output has reached an impressive 80,000 tons annually. This capacity allows us to service critical sectors across Asia, the Middle East, Europe, and South America. Every casting that leaves our factory floor is certified with ISO9001 and CE compliance, guaranteeing that your raw-material inputs and machinery parts meet strict international safety and quality standards.
Our focus remains on delivering industry value by combining advanced material science with green foundry practices. This enables global heavy-machinery and metallurgical enterprises to achieve maximum reliability.
To empower global industrial infrastructure with high-precision cast components, customized metallurgical engineering, and sustainable manufacturing processes that minimize lifecycle waste and maximize energy efficiency.
To act as the foremost trusted global foundry partner, continuously pioneering digital casting systems, advanced micro-alloying technologies, and resilient supply chains that support critical construction, mining, and metalwork operations.
A steel ingot mould is subjected to extreme thermal cycles, ranging from ambient temperatures to molten steel temperatures exceeding 1,600°C. Inadequate material engineering leads to premature cracking, structural distortion, and surface scaling. These failure points cause casting defects in the steel ingot, such as piping, chemical segregation, and surface voids.
We supply both flake graphite (gray cast iron) and spheroidal graphite (nodular cast iron) moulds. Gray iron offers superior thermal conductivity and damping capacity, ideal for rapid heat transfer. Nodular cast iron exhibits high tensile strength and yield toughness, drastically reducing thermal mechanical fatigue cracking under high stress loads.
By incorporating precise micro-alloying elements like Chromium (Cr), Nickel (Ni), and Molybdenum (Mo), we significantly suppress pearlite decomposition at high temperatures. Our engineering design calculations optimize the wall thickness ratio to prevent thermal gradients from inducing residual internal stresses.
High-grade mold coatings and shot-blasting treatments prevent steel ingots from welding to the mould walls. This facilitates easier stripping, preserves ingot surface smoothness, reduces scrap rates, and directly improves downstream rolling and forging efficiency.
As global heavy metallurgy adopts Industry 4.0 paradigms, the engineering of steel ingot moulds is shifting towards digitalization and smart monitoring. Henan Hanhai Metallurgy Mining is leading this transition by integrating advanced modeling and sensor technologies.
Before casting any heavy ingot mould, our R&D team runs advanced FEA thermal stress simulations. This predicts heat-flux dissipation profiles, identifies thermal concentration zones, and optimizes geometry to double the cycles a mould can survive (typical operational lifespan of 100+ casting cycles).
We are researching smart moulds equipped with internal temperature tracking ports. These allow real-time thermocouple connection, helping steelmakers monitor solidification rates and avoid internal shrinkage cavities in high-alloy tool steels and forging ingots.
Our future roadmap emphasizes green metallurgy. By establishing a scrap-return partnership program, worn-out moulds can be returned to our induction furnaces, promoting a zero-waste loop. This significantly reduces carbon footprints per ton of casting produced.
Collaborating with leading chemical research institutes, we are developing next-generation nanotechnology coatings that inhibit oxidation and decarburization of the mould interior, resulting in a cleaner cast structure.
Steel ingot moulds are not standalone components; they represent a critical phase in the macro-metallurgy value chain. Our products serve diverse, demanding sectors globally:
We supply large-capacity ingot moulds capable of casting forging ingots up to 120 tons. These ingots are processed into power generation shafts, marine propulsion cranks, and high-pressure chemical reactor shells.
For high-speed steels, chromium-rich die steels, and structural alloys, our moulds provide highly controlled cooling gradients. This reduces segregation and prevents internal macrostructural defects.
Leveraging our extensive mold inventory and 3D sand-printing capabilities, we rapidly scale production for customized shapes (such as octagonal, round, slab, and square designs) tailored to specific plant layouts.

Our commitment to quality is reinforced by ISO9001 and CE compliance certifications, ensuring global quality standards.
Procuring heavy casting equipment internationally requires navigating complex compliance structures and regional engineering codes. Henan Hanhai Metallurgy Mining addresses these friction points directly by offering robust localization support and absolute compliance guarantees.
Our CE mark is not a marketing tool; it represents conformance with the Machinery Directive 2006/42/EC and standard EN 1561 for founding and gray cast irons. This simplifies import procedures and installation authorization in the EU.
We deploy senior metallurgical engineers to offer on-site consultation and startup support. By bridging linguistic and technical gaps, we clarify casting tolerance configurations, material grades, and heat treatment limits.
We supply digital packages containing material test certificates (MTR) according to EN 10204 3.1. These detail ladle analysis, chemical composition, tensile tests, hardness profiles, and non-destructive examination (NDE) logs.
Operating in Henan, the industrial heart of China's heavy casting sector, we leverage a highly localized supply chain, raw material reserves, and digitized operations.
Our digitized sand preparation and resin-bonded sand line maintain dimensional stability within ISO 8062-3 CT12 standards. Continuous temperature control in our dual induction furnaces minimizes slag generation and inclusion flaws.
We source iron ore, high-grade scrap steel, and nodulizers directly from neighboring mining and refining clusters. This direct access buffers production against price volatility and raw material shortages, stabilizing lead times for urgent project cycles.
Our factory features double-housing gantry milling machines, heavy-duty vertical lathes (max machining diameter up to 8 meters), and deep-hole drilling equipment. This allows us to deliver moulds and crusher components completely machined, ready for installation.
