Why Ductile Iron?
- It’s strong
- It’s versatile
- It’s lightweight
- It’s cost-effective
Green Sand Foundry
We are proud to produce our ductile iron through green sand casting, which is a molding process that utilizes recycled sand as the main component. This casting method is referred to as “Green” since the main component is recycled sand and there are no other additives in the sand: just clay and water. The moisture content within the mold provides the binding structure for the sand.
