Foundry-Source Is Your Source For Grey Iron Castings

Grey iron also called grey cast iron

Much of the annual production of grey iron is in the form of grey iron engine blocks, grey iron c asted valves and grey iron casted pump housings. Grey cast iron is made in a grey iron foundry.

Foundry-Source works with grey iron castings from automated molding machines and high pressure machines; grey iron casting capability includes the cost efficient manufacture of large grey iron castings. Foundry-Source has grey iron castings made in several specialized furnaces used to melt the grey iron.

Foundry-Source also works with small grey iron casting castings from molding machines. The machines produce castings of grey iron ranging from a few pounds to more than 200 pounds.

The finished product of grey iron castings can be more geometrically complex than the product of a rolling, forging, or machining process like milling or turning. Grey iron castings are the original way to produce near net shape parts.
