Seneca Foundry Pours a Large Selection of Gray & Ductile Iron

Offering green sand molding, nobake molding, and lost foam processes, we are able to produce castings weighing from ounces up to 250 pounds. 

Although capable of doing high volume jobs, our niche is in low volume orders from 1 to 1,000 pieces.

Castings produced at Seneca Foundry are made according to ASTM A48 for Gray Iron and ASTM A395 for Ductile Iron.
Tolerances are based on ISO 8062-3:2007.  Please contact us to discuss special needs.
