What is Sand Casting Process?

Sand casting process is an industrial metal casting process that involves creating a mold from sand and pouring molten metal into it, generally used to cast the shaped parts of nearly any design, including large parts and those with internal passages. Baoding Guokun can produce various sand cast parts in cast iron, ductile iron, gray iron, low-carbon steel, mild steel, alloy steel for pump, valve, agriculture, railway, road, forklift, tillage, mining, automotive, medical, food, and aircraft, etc.

The process of Baoding Guokun sand casting involves several steps after producing a professional tool or mold, including:

No.	Steps	Details
1	Pattern Creation	A two-piece metal pattern is created in the shape of the desired part, typically from iron, aluminum or wooden material.For a single casting or small batches of castings, we prefer to produce to use the wooden material to manufacture the mold to save money for customers.For other sand casting parts in large quantity, we prefer to use aluminum or iron to improve the mold’s service life.
2	Mold creation	The two shell halves are joined together and securely clamped to form the complete shell mold. If any cores are required, they are inserted prior to closing the mold. The shell mold is then placed into a flask and supported by a backing material.
3	Pouring	The mold is securely clamped together while the molten metal is poured from a ladle into the gating system and fills the mold cavity.
4	Cooling	After the mold has been filled, the molten metal is allowed to cool and solidify into the shape of the final castings.
5	Raw Castings	After the molten metal has cooled, the mold can be broken and the casting removed. Trimming and cleaning processes are required to remove any excess metal from the feed system and any sand from the mold
6	Machining	Machining as per drawings

What is cast iron?

Cast Iron is an iron-carbon alloys with a carbon content 2-4% and silicon content around 1-3%. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are used in construction, transportation, oil and gas, pump, valve, marine, power, gearbox, agriculture and railway. In general, cast iron is notoriously difficult to weld.

The main types of cast iron are: gray cast iron, white cast iron, ductile cast iron and malleable cast iron. Baoding Guokun can select the suitable cast iron as per customer’s requirements and specifications. And the chemical composition of cast iron will be carefully inspected by Baoding Guokun’s spectrometer.

Gray cast iron	Gray cast iron is the most frequently type of cast iron. It is named for its gray fracture color due to graphite flakes in its composition. The grey cast iron has excellent compressive strength, and good machinability and limited brittleness.
Ductile cast iron	Ductile cast iron or nodular cast iron, is with graphite nodules that provide flexibility and toughness compared to gray cast iron, making the material less brittle overall. It has high tensile strength and impact resistance, making it a good choice for load-bearing components, such as automotive parts, gears, crankshafts, pump parts, gearbox, etc.
White cast iron	Named for its off-white color, which comes from iron compounds called cementite. White cast iron’s hard and wear-resistant surface makes it suitable for many wear-resistant applications, such as milling liners, motor frame, marine parts.
Malleable cast iron	Also known as malleable steel, it comes from annealed white cast iron. It’s resistant to wear and tear, has good plasticity and toughness, and is relatively easy to machine.
