Application: Agricultural Machinery

Sand casting foundry is the metal foundry mainly using sand casting process to produce metal castings made of gray iron ductile iron, cast steel, stainless steel, brass and aluminum alloys. Sand casting process is mainly used to produce grey iron castings and ductile iron castings. It could be divided into green sand, furan resin sand and pre-coated resin sand (shell molding) based on different sand materials. China iron and steel foundry with sand casting process and CNC machining. If you have any technical question or commercial inquiry, just feel free to contact us at any time.

Gray Iron Sand Casting Foundry from China with OEM Custom and CNC Machining Services.

Cast iron is an iron-carbon cast alloy with other elements that is made by remelting pig iron, scrap, and other additions. For differentiation from steel and cast steel, cast iron is deﬁned as a cast alloy with a carbon content (min 2.03%) that ensures the solidiﬁcation of the ﬁnal phase with a eutectic transformation.

Depending on chemical speciﬁcations, cast irons can be non- alloyed or alloyed. The range of alloyed irons is much wider, and they contain either higher amounts of common components, such as silicon and manganese, or special additions, such as nickel, chromium, aluminum, molybdenum, tungsten, copper, vana- dium, titanium, plus others. Generally speaking, the cast iron could be divided into gray iron, ducitle iron (nodular iron), white cast iron, compacted graphite iron and malleable cast iron.
