Know More About Grey Iron Casting Before Approaching A Manufacturer

Though various iron castings are manufactured nowadays, the demand for grey iron casting is always quite high. The primary difference between grey iron cast and other types of casting is that the former is cast with graphitic microstructure. As the name denotes, it is grey. It is a common cast alloy used for graphite lubricating due to its good machinability and low cost. Graphite flakes lubricate on their own and have a good wear resistance feature.

Difference Between Grey Iron And Other Cast Irons

The demand for grey iron is always quite high as it has less solidification shrinkage due to its graphite microstructure. Grey iron has silicon elements which increase fluidity and encourage good corrosion resistance during casting. Grey iron is also easier to weld as compared to other cast irons. It has low elasticity and cipf-es.org tensile strength. You don’t have to worry about its shock resistance capacity during casting. Sand casting is the commonly used process for grey iron castings. Sand is used as a mold media, which impacts the rate of solidification of the casting. The permanent mold process has a higher impact on the properties and structure.

Two Common Types Of Grey Iron Castings

• Lost Foam Casting

Lost foam casting is widely used during the casting process of cast iron components. This casting method offers numerous benefits and is widely used to make small grey iron investment castings. Few more benefits of using low foam casting are the production cycle becoming short, reducing mould cost, and improving the production process’s efficiency. Some Grey Iron Casting Manufacturers in West Bengal prefer the lost foam casting method as it helps in manufacturing products with higher accuracy. It also requires fewer machining operations and a good surface finish.

• Resin Sand Casting

The resin sand casting process is generally used for medium and small castings. Resin sand casting is more popular than other sand casting processes as the former is a more precise casting method. It is very similar to investment casting. Sand mould has high strength, while resin sand has good rigidity. It reduces the chances of shrinkage cavity and shrinkage defects.
