Grey iron castings from HULK Metal combine excellent vibration damping, wear resistance, and machinability, making them ideal for high-stress industrial components. We specialize in custom gray iron casting services tailored to client drawings, supporting complex geometries and tight tolerances. Backed by ISO 9001-certified production, advanced inspection protocols, and a responsive technical team, we deliver consistent quality for bulk orders across automotive, machinery, construction, and more—ensuring performance, reliability, and cost efficiency from prototype to mass production.
Grey iron castings (also spelled gray iron castings) are metal components produced by pouring molten iron—typically from the HT100 to HT350 grade range—into molds, where it solidifies into parts with a characteristic graphite microstructure. This graphite forms flakes that give grey iron its name, excellent damping capacity, good machinability, and thermal conductivity. Widely used in automotive brake discs, engine blocks, pump housings, machine bases, and valve bodies, grey iron castings offer a cost-effective solution for parts requiring dimensional stability and wear resistance under compressive loads. Their relatively low melting point and fluidity also make them highly suitable for complex sand or lost foam casting processes, which HULK Metal optimizes for bulk production with consistent quality and dimensional accuracy.
We analyze your part’s design complexity, required tolerance, surface finish, order volume, and application environment to select the most suitable method—typically sand casting for cost-effective bulk production or lost foam casting for intricate shapes—ensuring optimal quality, efficiency, and total cost control for your custom gray iron casting needs.
Our engineering team creates molds based strictly on your 2D or 3D drawings. We fabricate patterns, assemble mold boxes, and conduct trial runs to identify and resolve any issues, ensuring the final mold produces accurate, repeatable, and defect-free gray iron castings before mass production begins.
We procure certified gray iron scrap and ingots meeting HT100–HT350 specifications from long-term suppliers. Every batch undergoes spectral analysis and chemical testing in our lab to verify carbon, silicon, manganese, and other elements, guaranteeing consistent metallurgical properties before melting and pouring.
Using our ISO 9001-certified foundry lines, we melt raw materials in induction furnaces, pour molten iron into prepared molds, and control cooling rates precisely. This standardized process ensures structural integrity, dimensional stability, and high yield across large-volume gray iron casting production runs.
Each batch is tested for chemical composition, tensile strength, hardness, microstructure, dimensional accuracy, and surface defects. We use coordinate measuring machines, spectrometers, and metallographic equipment to validate compliance with your specifications and international standards before approving parts for shipment.
Castings are cleaned, treated, and packed according to your requirements—wooden crates for heavy parts, cartons for small components, or bulk pallets for high-volume orders. Our logistics team arranges sea, air, or land freight with real-time tracking to ensure safe, on-time global delivery.
After delivery, we provide full after-sales support. If quality issues are confirmed through inspection reports, we offer returns, exchanges, or restocking at no cost to you—ensuring your bulk purchase of gray iron castings remains secure, reliable, and backed by long-term accountability.

Treatment Type | Specific Methods & Description |
Mechanical Treatment | Includes shot blasting, sandblasting, grinding, and polishing. These methods clean casting surfaces, remove residual sand, scale, and flash, and improve surface roughness for painting or coating adhesion. Shot blasting also induces compressive stress, enhancing fatigue resistance—critical for automotive and machinery parts. HULK Metal uses automated shot blasting lines to ensure uniform finish on grey iron castings. These treatments are essential pre-steps before powder coating or inspection, and they do not alter the base material chemistry, making them ideal for dimensional-critical components requiring post-machining. |
Chemical Treatment | Involves phosphating, acid pickling, and rust-inhibiting washes. Phosphating creates a micro-crystalline phosphate layer that improves paint adhesion and corrosion resistance—commonly used for pump housings and automotive brackets. Acid pickling removes oxides and scale after heat treatment. These treatments are cost-effective and compatible with grey iron’s graphite structure. HULK Metal applies chemical treatments as pre-finishing steps to extend service life in humid or mildly corrosive environments. All processes comply with environmental standards, and wastewater is treated before discharge. |
Electrochemical Treatment | Primarily includes electrophoretic deposition (e-coating) and anodizing (less common for iron). E-coating provides uniform, pinhole-free paint layers even on complex geometries, offering excellent corrosion and chip resistance. While grey iron isn’t anodized, e-coating is widely used for appliance and automotive castings. HULK Metal partners with certified e-coating facilities to apply this finish as a primer or final coat. The process ensures full coverage, including internal cavities, and meets automotive OEM specifications for durability and environmental safety. |
Electrostatic Adsorption Treatment | Refers mainly to powder coating, where electrostatically charged powder adheres to grounded castings and is cured under heat. This yields a durable, decorative, and corrosion-resistant finish in various colors and textures. Powder coating is ideal for grey iron castings used in outdoor machinery, enclosures, or visible components. HULK Metal coordinates with trusted partners to apply polyester, epoxy, or hybrid powders. The finish withstands UV exposure, chemicals, and abrasion—enhancing both aesthetics and longevity without VOC emissions. |
Physical Treatment | Includes heat treatment (stress relieving, annealing) and thermal spray coatings (e.g., zinc or aluminum). Stress relieving reduces internal stresses from casting, minimizing distortion during machining—critical for precision machine bases. Thermal spraying adds wear or corrosion barriers for harsh environments. While not a surface “finish” in the cosmetic sense, these physical treatments significantly improve performance. HULK Metal integrates heat treatment into production workflows and sources thermal spray services for specialized industrial applications like mining or marine equipment castings. |
