IRON CASTING SERVICES
What are Iron Castings?
Iron castings are strong and durable components produced by pouring molten iron into molds through casting processes such as sand casting, shell mold casting, lost foam casting, and investment casting. Cast iron, the material used, is an alloy of iron with a relatively high carbon content (typically 2-4%), along with other elements like silicon, manganese, phosphorus, and sulfur. This specific composition is what gives cast iron its unique properties and versatility.
The material variety, including gray iron (great machinability and highly cost-effective), ductile iron (providing high strength and ductility), compacted graphite iron (great balanced strength, thermal conductivity, and machinability), and white iron (exceptional hardness and wear resistance), allows for a wide range of applications.
Our Iron Casting Processes
Taiyuan Simis is capable of investment casting, sand casting, and shell mold casting for manufacturing various types and grades of iron castings, including gray iron, ductile iron, white iron and compacted graphite iron (CGI). We tailor our processes to meet the specific requirements of diverse industries, such as automotive, railway, agriculture, mining and construction, engineering machinery, various pump and valves, providing quality iron castings for every project. We also offer both OEM and highly custom casting services to meet the unique needs of our clients.
Sand Casting
We provide sand casting service for various grades of cast iron, using a Disamatic line for high-volume and automated molding for diverse projects, handling parts from grams to over a ton. Our efficient core-making and temperature-controlled furnaces, coupled with expert staff, provide high-quality, timely sand cast iron components.
Shell Mold Casting
The shell mold casting process creates a thin, hardened sand-resin shell around a heated pattern, offering smoother surfaces and better dimensional control than traditional sand molds. We control our process for consistent shell thickness and density, producing superior iron castings. Our dedicated workshop uses advanced shell molding machines, automated mixing, and precise curing to optimize and guarantee consistent results.
Investment Casting
For complex, high-precision iron castings, the investment casting process surpasses sand and shell mold. While sand casting suits large, simple iron casting parts, and shell mold balances cost and precision, investment casting has a key advantage over sand casting in achieving intricate structures, and delivers tighter tolerances and superior surface finish compared to shell mold casting. Taiyuan Simis’ dedicated workshop specializes in high-quality ductile iron investment castings.

Our Iron Casting Expertise
At Taiyuan Simis, we offer expertise in casting a broad spectrum of iron types using investment casting, sand casting, and shell mold casting techniques, ensuring the optimal material selection for diverse applications.
Gray Iron: We are capable of casting gray iron, characterized by its flake graphite microstructure. This structure imparts excellent machinability, making it easy to shape and finish. Gray iron also exhibits good vibration damping properties, making it suitable for applications where noise and vibration reduction are important. Common grades we cast include ATSM A48 Class 20, 25, 30, 35, 40 and 50.
Ductile Iron: We routinely cast ductile iron, which offers a combination of high strength, ductility, and toughness due to its nodular graphite microstructure. Our casting processes are optimized to handle these grades, which offer higher tensile strength and impact resistance than gray iron while maintaining good machinability. We routinely cast ductile iron grades such as ASTM A536 60-40-18, 65-45-12, 70-50-05, 80-60-03, 100-70-03, and 120-90-02.
Compacted Graphite Iron (CGI): We also have the capability to cast compacted graphite iron (CGI), characterized by its vermicular (worm-like) graphite microstructure. This composition results in a balance of properties between gray and ductile iron, offering higher tensile strength, improved thermal conductivity, and better fatigue resistance than gray iron, while maintaining good machinability.
Other Iron Alloys: We also cast other iron alloys, including white iron and malleable iron, each with unique properties and applications. White iron is known for its extreme hardness and wear resistance, while malleable iron offers improved ductility and impact resistance compared to white iron.
The grades listed are examples of our standard cast iron offerings. Please inform us if you have particular grade requirements.
