Macro-Industry Engineering Solutions

Bridging the gap between metallurgy engineering and field reliability under extreme physical stresses.

Advanced Mineral Processing

We supply crushing components designed to withstand severe high-abrasion environments. By selecting high-chromium and manganese steel alloys, our castings improve the life expectancy of critical equipment components, preventing premature failures.

Thermal & Power Generation

Supplying massive turbine cylinders and housing blocks that remain structurally stable under cycling thermal expansion and internal steam pressures. Every casting is subjected to rigorous ultrasonic testing (UT) to verify defect-free structural density.

Heavy Forging & Hydraulic Systems

Large-tonnage casting for heavy machinery including rolling mills and forging presses. Our high-toughness casting options prevent dynamic stress fatigue in major structural frames, supporting continuous manufacturing lines.

Global Commercial & Industrial Status

As raw materials scale globally, high-capacity machinery demands reliable component supply chains.

The mining sector is demanding larger, more efficient machines to handle lower ore grades. As equipment scales up, components like jaw crushers, bearing housings, and slag pots face extreme mechanical fatigue. A single failure can stop production, costing operations thousands of dollars per hour.

At Hanhai Casting, we address this issue by providing reliable supply chains, consistent metal chemistry, and advanced CNC machining. By keeping entire processes in-house, we eliminate quality variance, giving global purchasers confidence that each component meets standard specifications.

Our Global Network Covers: Asia, the Middle East, Europe, and South America.

80,000-Ton Casting Capacity

Ensuring we can scale up production to meet the needs of large-scale infrastructure projects.

Technical Roadmap & Future Outlook

Improving manufacturing reliability through simulation technology, green casting practices, and digital quality monitoring.

Intelligent Foundry Simulation

We use MAGMA simulation software to model liquid metal flow and cooling rates. This helps us predict potential defects like shrinkage cavities or gas porosity before creating physical molds, reducing waste and ensuring component reliability.

Green & Clean Casting

We are upgrading our electric arc furnace systems with dust collectors and sand recycling systems. By recycling up to 90% of our molding sand, we reduce raw material consumption and lower the environmental footprint of our heavy casting operations.

Advanced Metallurgy Alloys

We are developing wear-resistant alloy compositions for mineral processing, including customized manganese and low-alloy steels. These materials are engineered to increase wear life by 20% to 35% in high-impact crushing applications.

Frequently Asked Questions

Technical answers about our casting processes, material standards, and order workflows.

Q: What international standards do Hanhai Castings comply with?
Our materials are cast to meet ASTM, EN, DIN, JIS, and BS standards. Common alloys we process include ASTM A27, A148 (carbon and low alloy steels), ASTM A128 (manganese steels), and ASTM A532 (abrasion-resistant cast iron). All chemical compositions and physical properties are verified in our laboratories before shipment.
Q: What is the maximum single-piece casting weight you can produce?
Our facility is equipped to handle single-piece castings from 1 ton up to 80 metric tons. Our cranes, melting furnaces, and sand molds are designed to handle heavy industrial components like rolling mill frames, crusher components, and slag pots.
Q: How do you prevent internal defects like shrinkage or air pockets in large castings?
We run simulation tests before pouring. Solidification software allows our engineers to locate riser positions and configure chilling patterns to avoid internal shrinkage. We verify the density of finished products using Ultrasonic Testing (UT) and Magnetic Particle Testing (MT).
Q: What heat treatment methods do you provide in-house?
Our heat-treating facilities provide annealing, normalizing, tempering, quenching, and solution treatments. Proper heat treatment is essential to achieve the hardness, tensile strength, and impact resistance required for heavy industrial applications.
Q: What is your typical lead time for custom OEM castings?
Lead times vary based on component weight and design complexity. Generally, pattern design and simulation take 2 to 3 weeks, molding and pouring take 3 to 4 weeks, and heat treatment, machining, and inspection take another 2 to 3 weeks. Typical lead times range between 8 to 12 weeks from technical sign-off.
Q: Can Hanhai perform finish machining on-site, or only rough castings?
We provide both. Our machine shop is equipped with vertical boring mills, portal milling machines, and CNC boring mills, allowing us to supply components fully machined to your specifications.
