A history built on material breakthroughs, capacity expansion, and strict compliance integration.
Hanhai Casting was established with a focus on heavy steel and iron castings, laying a solid technical and production foundation. Developed first-generation sand molds for metallurgy gearboxes.
Introduced advanced electric melting furnaces, automated chemical analysis spectrometers, and vertical lathe lines to serve the heavy-duty mining machinery and high-pressure cement sectors.
Achieved ISO 9001:2015 and CE certification. Upgraded destructive and non-destructive testing regimes (UT, MT, RT), exporting high-performance castings to Asia, Europe, and the Middle East.
Integrated intelligent foundry systems and digital management software (ERP & casting flow simulation), driving sustainable green manufacturing and strategic global custom partnerships.
Providing high-yield performance components across critical heavy industrial applications.
Widely used in mining, quarrying, and industrial recycling. We supply wear-resistant housings, flywheels, main frames, and eccentric shafts for jaw, cone, and impact crushers.
Large girth gears, riding rings, supporting rollers, and ball mill heads. High alloy steel and nodular cast iron optimized for high-torque rotary machinery operations.
Designed for forging, metallurgy, and automotive forming. Supports heavy-duty hydraulic press columns, crossbeams, cylinders, and highly stressed bolster plates.
High-strength, dense cast iron disc bodies, valve housings, and fluid control manifolds engineered to resist pressure drops, cavitation erosion, and chemical degradation.
Including high-performance slag ladles, ladle cars, smelting crucibles, and charging arms built to survive thermal shocks up to 1600°C without mechanical failure.
Full-service engineering matching of custom chemical composition requirements (ASTM, DIN, JIS, BS) with custom structural configurations to lower wear and weight.
Forging ahead with advanced structural simulation, green metallurgy, and micro-alloy optimization.
At Hanhai Casting, we have shifted from traditional empirical foundry layouts to scientific modeling. Using advanced computer modeling programs like MAGMAsoft and Finite Element Method (FEM) analysis, our metallurgists simulate molten metal velocity, pressure changes, temperature distributions, and solidification behavior prior to pouring.
This dynamic simulation reduces internal casting defects (e.g., shrinkage cavities, cold shuts, gas entrapments) by 98%. It allows our designers to refine riser sizes, chiller placements, and runner coordinates to guarantee consistent structural integrity across large components like 25-ton crystallizers and slag ladles.
To meet the extreme operational requirements of modern deep-pit mining, we modify steel and iron at the micro-structural level. Integrating small amounts of chromium, nickel, molybdenum, and vanadium yields superior toughness and wear resistance.
As carbon limits tighten globally, we have implemented green energy frameworks to support circular economies:

In-depth responses to common technical questions from global procurement and structural engineering professionals.
Cast steel is chosen when high tensile strength and impact resistance are required. For instance, jaw crusher swing jaws and cone crusher upper frames experience high impact stress and bending loads, making cast steel (like ASTM A148 or equivalent carbon/alloy grades) ideal to prevent sudden cracking.
Cast iron, specifically nodular (ductile) cast iron or gray cast iron with high damping capacity, is preferred for structures that experience constant vibration. Gray iron dampens mechanical vibration, protecting key bearing surfaces.
We apply a three-tiered quality assurance program:
Typical production lead times range from 45 to 75 days, depending on component mass, dimensional complexity, and machining specifications. This includes 3D modeling, mold design, pouring, stress relief annealing, final CNC machining, and inspection.
Shipping is coordinated through major ports (such as Qingdao or Tianjin). Large components receive specialized anti-rust coatings, custom timber blocking, and heavy metal bracing within flat racks or dry containers to prevent transit damage.
Yes. Our testing facility features high-accuracy optical emission spectrometers to verify chemical compositions in real time. We regularly manufacture castings to ASTM (US), DIN/EN (Europe), JIS (Japan), and BS (UK) standards, providing certified mill test reports (MTRs) with each delivery.
