Iron castings between 2kgs-60kgs are availble in this method. Clay sand casting is the second precision casting process with general casting tolerance CT9. It is able to produce iron castings less than 2kgs. Among them, precoated sand casting is the most precision sand casting process with general casting tolerance CT8. They are precoated sand casting, resin sand casting and clay sand casting. In China, there are three types of sand casting techniques to make iron castings. Sand casting is used to produce a wide variety of cast iron components with complex geometries. Is the process that utilizes non-reusable sand molds to form metal castings. Sand Casting: Also called sand molded casting.
Simply speaking, iron castings could be customized in sand casting or lost foam casting technics. Like steel casting, there are also different kind of methods of producing iron castings. They may also have more casting defects than grey iron casting.Ĭommon Used Material Standards in Iron Casting: Cast Iron The production of ductile iron casting is more complex and expensive than grey cast iron. They are used in a wide range of industries: engineering, agriculture, automotive, road and construction, etc. They have high strength, high heat-resistance and toughness. It is often used to manufacture parts like cylinder blocks, pistons, gear boxes, knives, table wheels, pipes, valves, etc.ĭuctile Iron Casting: In Ductile iron, the graphite is like a pillow and acts as “crack-arresters” to give ductility and toughness superior to all other cast irons. It, however, has low tensile strength and elongation properties. It can withstand greater load and has a good degree of resistance against corrosion. It has good casting properties, high machinability, good wear resistance as well as good vibration damping. Grey Iron Casting: Grey iron is called that because when it is fractured, its surface appears a dull grey color. The difference in these types of iron is the characteristics of the graphite used in the material. We can divide cast iron into grey cast iron, ductile cast iron and malleable cast iron.
Compared with steel casting, iron casting has a wide range of advantages of few less lucrative properties. Iron castings can be used in a variety of industries and employed for an array of uses.Ĭast iron is an alloy of iron, carbon and silicon with carbon levels of about 3.2% and silicon at about 2.2%. They are allowed to cool down and solidfy before being removed from the molds and used. Iron casting, one of the oldest and most recognized casting methods, is melted and poured into molds or casts to creat a part of products of desired dimensions and shape.
