Kaédi, situated strategically along the Senegal River valley, serves as a vital economic transit point between Mauritania and West African markets. With regional developments in mining exploration, hydraulic infrastructure, and aggregate production expanding across the Gorgol region, local industries demand high-integrity equipment components capable of resisting severe thermal fluctuations, high sand abrasion, and remote operational stress.
Procuring industrial-grade steel castings and replacement parts for heavy jaw crushers, mining sumps, or turbine cylinders represents a major operational hurdle for local enterprises. Hanhai Metallurgy Mining bridges this gap by offering direct export avenues, optimizing sea freight to Nouakchott, followed by synchronized overland logistics to Kaédi, backed by comprehensive compliance certifications.
As a premier, specialized foundry manufacturer operating from China’s heavy-industry heartland, Henan Hanhai integrates advanced structural design, precision steel/iron casting, and heavy-duty machining. We maintain an annual casting capacity exceeding 80,000 tons of certified metal components.
Our engineering workflows meet international standards including ISO 9001 and CE compliance certifications. By focusing on high-stress mining structures, crushing machinery components, and metallurgy process equipment, we guarantee operational run-times that directly reduce downtime for remote operations globally.
Established Hanhai Casting with a focus on heavy steel and iron castings, laying a solid technical and production foundation.
Introduced advanced melting and molding technologies, expanding production capacity to serve key metallurgy and mining sectors.
Achieved comprehensive ISO9001 certifications, upgraded non-destructive testing systems, and initiated international export routes.
Integrated digital management, simulation-assisted casting modeling, and robust export supply lines serving global growth markets.
To provide structural components that survive extreme mechanical loads, Hanhai implements metallurgical simulation software alongside strict testing procedures. This ensures our castings meet standard specifications for impact toughness, fatigue resistance, and dimensional accuracy.
| Component Type | Standard Material Grades | NDT Quality Guarantee | Application Scenario |

| Hollow Shafts & End Caps | ZG270-500, ZG310-570, GS20Mn5 | 100% Volumetric Ultrasonic Exam | Heavy ball mill and rotary kiln transmissions |
| Valve Bodies & Cylinders | WCB, WCC, LCB, WC6, WC9 | Pressure & Leak Integrity Verified | High-pressure hydraulic & fluid piping plants |
| Slag Ladles & Smelting Pots | ZG230-450, ASTM A27 Grade 65-35 | Thermal Cycling Stability Analysis | Metallurgical slag handling up to 1600°C |
Customers submit CAD drawings, operating conditions, mechanical load patterns, and metallurgy specifications. Our engineering team reviews critical tolerances and load zones.
Hanhai runs numerical simulations (MAGMA/ProCAST) to predict cooling phases, eliminate shrinkage porosity, and optimize mold gates and risers before pouring.
Using electric arc furnaces and ladle refining, we clean molten steel chemistry. Sand molds are prepared via automated production loops for high dimensional consistency.
Normalizing, tempering, or quenching steps are calibrated via automated ovens. This step relieves residual casting stress and establishes optimal yield/tensile strength ratios.
Equipped with heavy CNC vertical lathes, boring tools, and portal milling machines, Hanhai finishes key assembly tolerances to exact engineering layouts.
Parts are coated with rust-preventatives, secured in heavy steel-reinforced crates, and shipped via ocean cargo to Mauritanian ports with full custom clearance documentation.
Delivered to mine operators, smelting factories, and plant systems worldwide.
