A visual look into our physical capacity, highlighting high-frequency induction furnaces, molding configurations, and heavy machining centers.
Addressing how heavy-duty machinery segments combat severe fatigue, rapid mechanical wearing, and complex chemical processes globally.
Heavy machinery operates under continuous pressure. We utilize custom alloy steel containing critical levels of Chromium, Molybdenum, Manganese, and Nickel. This specific design ensures superior surface hardness while preserving vital shock-absorbing elasticity in the component's core.
To eliminate internal stresses generated during casting, parts undergo micro-controlled annealing, normalizing, tempering, and liquid-quenching procedures. This carefully managed process refines grain matrices, maximizing load tolerance and fatigue performance.
European markets require compliance with the Machinery Directive (2006/42/EC). We design parts to meet exact safety criteria. Our castings undergo Finite Element Analysis (FEA) to confirm safety factors before manufacturing begins.

Delivering wear monitoring guides, recommended lubrication schedules, and component usage instructions.
Providing rapid shipping on replacement parts, tracking wear performance, and updating alloy designs based on service feedback.
Our components are engineered for challenging operational settings. In remote, high-altitude South American mining applications, our CE-certified jaw plates resist cracking under freezing conditions and dynamic shock loads. In hot, dusty Middle Eastern cement plants, our heavy casting support sleeves maintain structural stability without dynamic oil film breakdown.
To support international buyers, we provide localized compliance documentation. All exports include complete material melt tracing sheet records, chemical analysis certification, and NDT compliance reports. This ensures trouble-free import clearance and simple technical audits for local engineering teams.
We collaborate with global engineering contractors and industrial machinery manufacturers. Below are our partner references and official ISO and CE validation images.
A catalog of custom heavy-industry parts manufactured and shipped to client installations worldwide.
We integrate sustainability, automated metallurgy, and clean processes to align with global environmental benchmarks.
The manufacturing of heavy machinery parts requires balancing high strength with environmental responsibility. Hanhai Casting's technical roadmap prioritizes process optimization. By upgrading to electric arc furnaces and high-frequency induction units, we have reduced carbon emissions from primary melting stages while refining chemistry control for critical alloys.
We are also implementing 3D sand-printing for quick prototyping and to produce complex internal features. This approach reduces overall mold weight, minimizes material waste, and helps bypass traditional wood pattern tool cycles.
Our engineering team answers frequent technical questions from industrial operators and procurement managers.
We design and manufacture our parts to align with the Essential Health and Safety Requirements (EHSR) under the Machinery Directive 2006/42/EC. We verify tensile performance, material properties, impact resistance at low temperatures, and conduct full ultrasonic examinations. We issue a Declaration of Conformity and provide traceable heat stamp markings on every part.
For high-wear components like jaw crusher plates and impact crusher hammers, we typically utilize high-manganese steels (such as Mn13Cr2, Mn18Cr2, or Mn22Cr2) and high-chromium white irons. These materials harden under impact stress, extending service life in abrasive environments.
We use multiple non-destructive testing (NDT) methods. Ultrasonic testing identifies sub-surface voids or cracks, magnetic particle testing checks for surface discontinuities, and radiography is used on critical high-stress zones. All inspections are documented for compliance review.
Yes. Our engineering division works with CAD files, SolidWorks, and STEP configurations. We run solidification simulations to identify and address potential shrinkage zones prior to producing patterns.
We apply heavy-duty rust-preventative wax or polymer coatings to machined surfaces. Parts are wrapped in moisture-resistant barrier film, packed with desiccants, and secured in steel-reinforced wooden crates designed for sea transport.
