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 CastingĪlso called sand molded casting. In our Iron cast foundry, there are 2 main methods for iron casting: sand casting or lost foam casting method. Like other investment castings, there are also different producing methods of iron castings. The iron cast is the main raw material for Iron casting.
Here graphite is present in the form of spheres or nodules. Like brake supports, hubs of wagon wheels, etc. They are used to make parts where forging is expensive They are made malleable with the help of annealing. TypesĬarbon is present here in the form of Iron carbide (Fe3C).Ĭarbon here is mainly in the form of graphite. Here we make a brief introduction in the below table. The Iron Cast main types are Grey Iron, Ductile Iron, Compacted graphite, White, Malleable, Abrasion-resistant, Nodular or spheroidal, Austenitic. Constant Mechanical properties between 20 to 350 degree Celsius.Excellent anti-vibration (or damping) properties hence it is used to make machine frames.Strong compression strength compared to steel.Good machinability (graphite cast irons).Good casting properties(low Tm, good fluidity).It can be given any complex shape and size without using costly machining operations.
