Iron Sand Casting Iron sand casting can produce good surface finish, high dimensional standard steel castings which widely used in sand casting foundries. Learn More >

ADI Castings Aus tempered Ductile Iron (ADI) is a high-strength, tough, and wear-resistant material produced through a specialized heat treatment process applied to ductile iron castings. ADI combines the inherent benefits of ductile iron, such as excellent castability and machinability, with superior mechanical properties achieved through austempering. Learn More >

Copper Sand Casting Copper Sand Casting is a versatile and widely used process for creating copper and copper alloy components in industries where properties like high conductivity, excellent corrosion resistance, and mechanical strength are required. Copper casting is highly beneficial for producing parts that are exposed to extreme environments, electrical systems, or decorative finishes. Copper’s inherent characteristics make it a sought-after material in industries such as electrical, plumbing, automotive, marine, and art. Learn More >

Ductile Iron Sand Castings Ductile Iron Sand Casting (also known as Nodular Cast Iron or Spheroidal Graphite Iron) is a type of cast iron that incorporates small amounts of alloying elements, such as magnesium, to promote the formation of graphite in spherical or nodular form. Learn More >

White Iron Sand Castings White iron is a type of cast iron that is characterized by its white, crystalline fracture surface. Unlike other forms of cast iron such as gray iron or ductile iron, white iron has a high carbon content in the form of cementite (iron carbide), which makes it extremely hard but also brittle.

Resin Sand Casting Alkline Phnolic Resin sand can produce good surface finish, high dimensional standard steel castings which widely used in the sand casting foundries, suitable for manufacturing from 100kg casting to 20-ton casting, 30ton casting, max weight 80ton casting per pc. Learn More >

Steel Sand Casting Steel sand casting is a versatile and widely used manufacturing process in the production of steel components. It involves pouring molten steel into a mold made of sand to create the desired shape. This process is especially useful for producing complex, large, or heavy steel parts. Below is a detailed explanation of the process, applications, and advantages of steel sand casting. Learn More >

Vacuum Lost Foam Casting Lost foam casting (LFC) is an innovative and efficient metal casting technique that uses a foam pattern, typically made of expanded polystyrene (EPS), as the model for the desired part. Learn More >

Furan Sand Casting Furan Sand Casting is a specialized type of sand casting process that uses furan resin as the binder material instead of traditional clay or other bonding agents. Furan resin is a synthetic organic compound that, when combined with sand, forms a mold that is stronger, more durable, and can handle more complex shapes compared to conventional sand casting. Learn More >

Water Glass Sand Casting Water Glass Sand Casting, also known as Sodium Silicate Sand Casting, is a casting process that uses sodium silicate (water glass) as the binder to create molds for casting metal parts. This process is particularly suitable for high-precision parts and produces castings with a high-quality surface finish and dimensional accuracy. The primary difference between water glass sand casting and traditional sand casting (which typically uses clay or furan resin as binders) lies in the type of binder and curing method used. Learn More >

Vacuum Sand Casting Vacuum Sand Casting is a precision casting process that combines traditional sand casting techniques with the application of a vacuum to enhance the quality of the mold and the casting process. This method is particularly used to create high-precision and high-integrity castings in industries that require parts with minimal defects, excellent surface finishes, and tight dimensional tolerances. Learn More >

Gravity Sand Casting Gravity Sand Casting is a widely used, cost-effective casting process where molten metal is poured into a sand mold under the influence of gravity. It is one of the simplest and most traditional casting methods and is commonly used for producing a wide range of metal components, from small parts to larger, more complex components. Gravity sand casting is ideal for parts that require good strength, precision, and cost-effectiveness but do not necessarily need to meet the high-performance requirements of more advanced casting methods like investment or die casting. Learn More >

Aluminum Sand Casting Aluminum Sand Casting is one of the most widely used casting processes for producing aluminum parts with complex shapes and high precision. It combines the flexibility and cost-effectiveness of sand casting with the excellent material properties of aluminum alloys. This process is suitable for various industries that require lightweight, durable, and corrosion-resistant components. Learn More >

Brass Sand Casting Brass Sand Casting is a casting process used to produce high-quality brass components, which are widely used in various industries due to the material’s excellent corrosion resistance, machinability, and aesthetic appeal. Brass, an alloy of copper and zinc, offers good strength, ductility, and resistance to corrosion, especially in marine environments and harsh industrial conditions. Learn More >

WALKSON Steel Casting Advantage

WALKSON steel casting foundry had been working on steel casting for decades, we manufacture low alloy steel casting, stainless steel casting, etc..

Firstly, WALKSON have advantaged equipment for sand mould casting process. We have 2 sets EAF(Electric Arc Furnace) and one set AOD(Argon Oxygen Decarburization Furnace) for our metal refining, which can produce higher purity of molten steel, secondary the EAF(electric arc furnace uses scrap steel as the main raw material, so the electric arc furnace steelmaking can reuse the alloy elements in the scrap steel, this 2 area will absolutely ensure WALKSON steel casting have high-level quality castings and reduce the sand casting cost to buy high-quality scrap metal which benefits our customers on the cost but the quality is on the top level of our casting. With the electric arc furnace and argon oxygen decarburization furnace, we are on the top level in china's sand casting foundry.

Secondary our steel casting Heat treatment furnace and quench tank (with the stirring system) which can ensure our steel casting manufacturing process can reach high stand mechanical property, include Charpy test, tensile test, and hardness test, with this equipment, our sand casting factory can produce high-level steel castings and improve the casting life a lot.
